Table of contents: Buying guide Top 30 KNX push buttons
A KNX push-button controls the room temperature and switches the light and shading in the room. Some have an integrated heating controller or humidity sensor: We compare the top 30 of the world's best KNX switches in terms of material quality, features and functions.
Curtain up for our “Longlist of the best KNX push-buttons”: Which KNX switches will be able to control the individual rooms in the house in 2024? Or should we rather say KNX push-buttons? Both terms mean the same thing – it’s about control in a networked house using a smart light switch.
We compare the top 30 best KNX push-buttons on the global market: Basalte Chopin, Basalte Fibonacci and Basalte Sentido V4, the aged Berker B.IQ push-button sensor, Berker S1930 R.classic, Enertex MeTa KNX Premium and the brand new Enertex MeTa 2 Premium, the Italian Ekinex Signum and Ekinex FF and 71 series, Gira Tastsensor 4 Komfort, Jung F40 and Jung F50 Tastsensor and Jung LS Touch, the price bangers and German perennial favorites MDT Glastaster II smart and MDT Glastaster light, the invisible Enertex ProxyTouch KNX, the high-quality Enertex MeTa Premium, the brand new Theben iON KNX and many other new products.
What all KNX push-buttons have in common is the significantly higher current requirement compared to the past, which can only be covered by a current KNX power supply unit – see KNX power supply units 1280 mA in comparison (Top 5 comparison test).
When it comes to high quality and workmanship, good design and aesthetics and as many functions then the KNX push-buttons presented by us are a good basis for selection. The variety of KNX push-button designs is often one of the arguments for building owners to opt for a KNX smart home in new builds or renovations. And this goes as far as the Smart Home Villa – see our article ” Top 10 criteria and features of a smart home luxury villa“.
And first of all: the choice of the most suitable KNX push-button or KNX light switch is a decision for many years, often for several decades. Most of the KNX switches presented here are designed for long-term use in apartments, houses and villas and can be brought up to date with updates. This is definitely sustainable.
The situation is similar when it comes to choosing the right heating actuator, see our Comparison test of the top 5 KNX heating actuators.
Note: Like our other comparison tests, this article is updated regularly. This top 30 of the best KNX push buttons is therefore a snapshot that may change in the coming weeks and months. This also applies to the prices.
Purchasing advice: What can a KNX push-button basically do?
There are currently 85 different manufacturers on the market – as of November 2024, offering a total of approx. 1200 different KNX push-buttons or KNX switches, we have counted them roughly. No other smart home system in the world offers more choice, more variants in terms of quality, equipment and individual adaptation to the living situation, ambience and interior design! Nowhere else are there so many different smart light switches.
A time-honored villa on Lake Starnberg is served just as well as the minimalist wooden detached house in the Tyrolean countryside or the terraced house with a lot of the client’s own work in the outskirts of a large city. KNX light switches are used everywhere! And these must suit the living ambience, the respective budget and their functional equipment!
We present the world’s best KNX push-buttons, which have undergone an extensive test run. What makes up this compilation? It is our practical experience with newly built houses, high-end smart homes, luxury villas and the very good knowledge of the market and the feedback from many builders that have created and constantly expanded this top checklist of KNX switches/buttons.
Basic (multi-) functions of KNX push-buttons
- Control room temperature (only models with integrated room thermostat)
- Room temperature measurement (all)
- Room humidity measurement (optional)
- Room brightness measurement (optional)
- Switch light, shading, ventilation, heating, sockets at the touch of a button
- Dim light, dim-to-warm, set colored light/color values
- Call up scenes (light, blinds, music, switching functions, etc.)
- Save KNX scenes (optional)
- Room temperature display (only KNX push-button with display)
- Status display (light, shading, day/night, etc.)
- Display of fault messages (KNX push-button with display)
- Day/night display switchover (optional)
- Night light and orientation lighting (optional)
For anyone familiar with a conventional light switch from the analog (and even modern) era, a KNX push-button with its comparatively infinite capabilities is a small marvel. It can record values such as the room temperature and room humidity, display the status of the individual buttons if required or function as a night light or orientation light.
A KNX push-button is basically the control center in a room, where all things such as lighting, shading, heating/cooling, ventilation and switchable sockets are operated.
The advantage: where previously endless switch batteries had to be placed, there is now a single KNX push-button. And it can do much more than the switch batteries still found in larger residential buildings by some property developers and clueless electricians. The list above shows the basic possibilities/functions that can be implemented with a KNX push-button in 2024.
By now it should be clear that a KNX push-button cannot be compared with a conventional switch and, thanks to its wide range of functions, always pays off in terms of budget. For this reason alone, we offer this manufacturer-neutral purchasing advice for all builders and prospective buyers of new buildings.
KNX push-button operation: by click or touch?
In principle, there are two different ways of operating KNX push-buttons: one reacts to a button click (as a rocker or push-button) and the other to a simple touch (capacitive KNX push-button). And then there is the exception with gesture control, which is limited to the Enertex ProxyTouch. As the push-buttons are visible to everyone on the wall for many years – probably decades – and are also the figurehead of the respective room, great care should be taken when selecting the right KNX push-buttons.
On the one hand, a KNX push-button can be replaced by another model at any time, but on the other hand, there is the old adage: buy cheap or buy wrong and you buy twice.
Whether a room is operated by touching a button or by a haptic click (sound) with feedback is still a matter of personal taste. We find that there are good representatives for both the one and the other concept. Curtain up for our big comparison of the best KNX push-buttons (or KNX switches) in the world, which is constantly updated.
Differences in the equipment of KNX push-buttons 2024
- KNX push-button with bus coupling unit (all have, as of 2024)
- KNX push-button with temperature sensor (all have, as of 2024)
- KNX push-button with integrated room temperature controller (only some, as of 2024)
- KNX push-button with humidity sensor (now some)
- KNX push-button with display (no longer so trendy, as of 2024)
- KNX push-button with binary input (very few)
- KNX push-buttons with electronic button labeling (very few)
- KNX push-button with dimmable night light (some have, absolutely on trend 2024)
- KNX push-button with proximity sensor (a few have, fully in line with the 2024 trend)
- KNX push-button with force feedback and acoustic feedback (one single button)
Wall installation and connection: KNX push-button or KNX switch
Just like a conventional switch in the room, each KNX push-button requires a 60 mm or 68 mm (diameter) box for wall installation and an electrical connection cable. The box must be milled into brick or sand-lime brick using the appropriate tools. The KNX push-button uses the same cable for power supply and data transmission for switching etc.: via the green KNX bus cable with 30 V DC voltage!
KNX push-button with temperature sensor + room temperature controller
Let’s take a look at an important feature that all KNX push-buttons have in common: The integrated temperature sensor for measuring the room temperature. The latter is used to control the (floor) heating in the respective room in conjunction with a KNX heating actuator including heating controller, which is located in the control cabinet/electrical distributor.
As all of the KNX push-buttons we tested here are equipped with a temperature sensor, the temperature can be measured in every room. In addition to the temperature sensor, some KNX push-buttons are also equipped with a room temperature controller – also referred to by the abbreviation“KNX push-button with RTC“.
From our point of view KNX push-buttons with room temperature controllers are no longer so trendyas the heating controller is integrated in the KNX heating actuator (in the KNX control cabinet) anyway. As a result, equipping the KNX push-button with a temperature sensor is sufficient today. More details on the subject of heating control provides our Top 5 comparison of KNX heating actuators (comparison test).
KNX push-button with display: no longer so trendy!
Let’s move on to an equipment feature that is no longer so trendy today: A KNX push-button with display. While 15 years ago it was absolutely hip to integrate an expensive push-button (such as the Berker B.IQ with its cool stainless steel rockers) with a built-in mini display in a classy ambience, KNX touch panels do the job today – see also our blog post Comparison of the top 5 KNX touch panels.
Conclusion on this topic: A KNX push-button today is visually reduced to the essentials and more and more manufacturers are dispensing with the display. There are also exceptions here in our comparison test of the top 30 KNX push-buttons, of course.

Our comment: At first glance, the market for KNX push-buttons is unmanageable. Every manufacturer advertises its products as the ultimate in the respective segment – whether entry-level, mid-range or high-end. However, there are basic features which, in our experience, are generally valid.
The table above provides an overview of the differences in the features of KNX push-buttons in the individual segments. The transitions between the individual market segments are fluid.
KNX push-buttons up to 150 euros: entry-level class
1st place: MDT Glastaster II smart
And here comes a bombshell that packs a punch: The German company MDT is mainly responsible for the sharp price drop of up to 30 percent in KNX actuators and KNX sensors across the entire market over the past 10 years. No joke! The company has attacked the established competition from Berker, Busch-Jaeger, Gira, Jung, Merten and Siemens at full throttle.
Many builders, especially private house builders, rely almost exclusively on KNX actuators from MDT in the control cabinet for cost reasons. Thismakes some electricians, who previously purchased and installed the push-button competition from wholesalers, red in the face. The next few years will show whether this decision was the right one.
MDT also has some real price bangers in its range of KNX push-buttons, where the competition can only keep up to a limited extent or not at all. One of the most popular and best-selling KNX push-buttons of all is the MDT glass push-button II smart, which has been available for some time in “black” and as Series 02 in addition to the classic white version. The MDT glass push-button II smart can therefore be regarded as the“VW Golf of KNX push-buttons“. Or is it the Skoda? Joking aside.
MDT has been offering the Glastaster since 2014, which was expanded to Glastaster II smart in 2016. For those who remember the company from earlier days: MDT offered inexpensive memory modules for Windows PCs in the early 2000s and therefore has a good handle on semiconductors and production.
MDT is now in the hands of a Norwegian investor who has big plans for the company. At the beginning of 2024, MDT took over the small Belgian manufacturer Tense, which also produces KNX push-buttons. Malicious tongues claim that Tense often looked to Basalte for design.
Quality and workmanship: Good
To make it clear right away: The MDT glass push-button II smart is well made despite its low price. In view of the price range, it should come as no surprise that the top performance of the KNX push-button upper class is not to be expected. The MDT KNX push-button reacts to touch (capacitive) and has an integrated LCD display with backlighting. The design of the icons can be customized and the labeling is flexible for all buttons and functions. There is certainly no accounting for taste.
What is noticeable with some glass grids after mounting them on the wall is that they can be twisted a little too easily and may hang slightly askew as a result. However, this is only noticeable on very close inspection.
Functions: Very good basic equipment
No other manufacturer offers more functions in this price range: For technology enthusiasts and non-design fans, the glass push-button, which should really be called a Plexiglas push-button (in terms of appearance), is an extremely good choice. In upmarket houses in the suburbs, the Glastaster II smart will only make it as far as the basement, as it is usually the woman who decides on the purchase of KNX switches or KNX push-buttons.
Conclusion: It couldn't be cheaper
For just under 150 euros, no other manufacturer manages to offer such a well-equipped KNX push-button with display. Weaknesses can be seen in the material appearance, the visual appearance and the graphic design of the icons on the display. If you have calculated your smart home with KNX very tightly, you should urgently choose the MDT glass push-button II smart or the even cheaper MDT glass push-button II light – for the whole house.
The MDT Glastaster II has made it possible for many builders of new homes in the mid-range segment to consistently rely on the KNX system and take the right path. Bravo MDT!
(The Glastaster II smart (since 2016) is at the cutting edge of technology and the range of functions far exceeds what we are used to in this price segment. Since 2019, the Glastaster II smart has also been available in a black version. In our opinion, this looks better and avoids the “Plexiglas look” of the white version.
MDT Glastaster II smart rating
Overall ranking: 1st place (beginner class)
2nd place: Theben iON 104/108 KNX push-button
The German company Theben, based in Haigerloch on the edge of the Black Forest, is one of the founding members of the KNX standard. In view of the company’s long history, the Theben iON 104/108 KNX push-button is still very young: it was launched in 2018 and is available as a 1-gang and 2-gang push-button sensor and as a version with room temperature controller and display.
Although the Theben iON is aimed more at the lower price segment, the push-button is well made and offers both a defined button click and a good pressure point. This makes the price for the top model, the Theben iON 108 KNX, all the more surprising, as it is calculated at just under three figures including German VAT.
The simpler Theben iON 104 KNX without display and RTR is available for almost half the price. The Swabians from the Black Forest have a real price hit on offer here.
Quality and workmanship: High-quality plastic
The Theben iON 104/108 KNX push-button has nothing to hide: In terms of quality appearance and feel, it can compete with more expensive plastic push-buttons such as those from Gira or Jung. We really like the slightly rounded edges and the subtle sheen of the plastic.
Functions: Temperature sensor, status LEDs and KNX Secure
It is easy to see that the Theben iON KNX push-buttons were fundamentally developed in 2018: KNX Secure data encryption is supported, which most KNX push-buttons in our large comparison are not yet able to offer.
Compared to the competition, Theben, as a newcomer/manufacturer in the KNX switch environment, offers a choice of three different functions per individual button: short, long or double-click can be set. The same applies to the selectable colors of the status LEDs, which can pulsate, flash or light up continuously.
Conclusion: Push-button for beginners looking for good value for money
At first glance, the Theben iON 104 or 108 is fairly inconspicuous both as a KNX push-button without/with display. The second glance shows: It offers good features at a very good price – even for less than 100 euros. The workmanship of the plastic push-button is definitely good and the version with display can certainly compete with the more expensive competitors – also from Germany.
Many customers will opt for the good Theben iON 108 for room control as part of Theben’s “KNX Light” version – LuxorLiving.
Theben iON 108 KNX rating
Overall ranking: 2nd place (beginner class)
3rd place: Jung F40 push-button sensor
The German company Jung is one of the pioneers in the field of KNX push-buttons and the KNX bus system in general. The F40 push-button sensor – which really has nothing to do with Ferrari’s super sports car, the F40 – is available for a wide variety of frame variants and switch designs, primarily made of plastic.
If you want something really chic, go for the LS series and then the LS990 colors of Le Corbusier. It costs considerably more, but looks really good. If you want to order unusual Le Corbusier colors, you can expect to wait several weeks. How do we know that? We have experienced it ourselves often enough.
From our point of view, the LS series with its narrow frame is best suited for use in a modern new-build smart home, although as with most KNX push-buttons, it is always a question of personal taste and the design of the room/object.
The LS series can be combined with different frame colors and materials (including metal) to create real eye-catchers on the wall – if desired at all. The Jung push-buttons in the LS series are architects’ favorites – at least in Germany.
They are simple in design and can also be placed in a smart home villa. Would we do that? No, definitely not, there are completely different candidates in this top 30 overview.
Quality and workmanship: Good
Compared to the significantly more expensive KNX buttons with solid metal buttons and surfaces, it is in the nature of things that plastic buttons convey a different click feel and therefore do not come across as being quite as high-quality.
It can be a little grating at times. Anyone who starts to complain here will have to dig deeper into their pockets. All in all, the workmanship can be described as good and the keys should be very “easy to clean” for many years. The plastic button surfaces are not scratch-resistant, but this is hardly noticeable overall.
Functions: Solid basic equipment
Each Jung F40 KNX push-button has an integrated sensor for measuring the room temperature. The buttons can also be labelled, so there are many options for individualization. A status LED can also be parameterized for switching functions. This looks good and is well received by building owners, as we have often experienced.
Conclusion: For property developers and apartment buildings
The Jung F40 push-button sensor is on the program when a property developer sells the same number of residential units in the high-end segment and as “Smart Home” or “Luxury KNX”. Many push-buttons can then be installed in apartments and rooms at favorable conditions – at well under 100 euros each. Incidentally, electricians also like to do this when it comes to larger projects.
Jung F40 push-button sensor rating
Overall ranking: 3rd place (beginner class)
4th place: Gira KNX push-button
What is there to say: The Gira KNX push-button has been new on the market since 2019 and is particularly aimed at private builders. Or those who previously had to deal with “normal” switches from the old analog electrical world and for whom“smart home” wasmore of a foreign concept.
On the other hand, the design and overall appearance of the simple KNX switch is anything but “basic”: it is available as a 1-gang or 2-gang version in various colors. In terms of price, the Gira KNX push-button is positioned as inexpensively as one would not have expected from Gira – at well under 100 euros.
This is certainly the result of the increased competition in the lowest segment of KNX push-buttons – especially those from MDT. The black version of the Gira KNX push-button looks almost a little classy compared to the silver version.
Gira KNX push-button Rating
Overall ranking: 4th place (beginner class)
KNX push-buttons up to 250 euros: The middle class
1st place: Berker B.IQ push-button sensor
The German company Berker, based in Schalksmühle, made a name for itself very early on for high-quality workmanship and, above all, very good design in KNX push-buttons. The development of the Berker B.IQ KNX push-button sensor dates back to the mid-2000s, in 2005 to be precise. Then as now, the elegant KNX push-button or KNX switch impresses with its material appearance and the highest quality of workmanship. Low fitting tolerances were already a major issue back then, which is far from being a matter of course for all manufacturers today.
Following the takeover of Berker by the much larger company Hager (2010), innovations in the KNX sector are no longer quite as much in focus as they used to be – or so one might think.
We also show the Berker B.IQ as a KNX push-button in the article comparing the “Top 10 push-buttons & touchscreens for KNX home control“.
Quality and workmanship: Simply top for decades!
Very good workmanship, also in view of the really heavy stainless steel rockers, which have maintained their low fitting tolerances even after many years (>15). Scratch-resistant with a clean click feel and perfect surface feel, the Berker B.IQ KNX push-button sensor can certainly last for decades. No joke! We have experienced it!
Functions: You can do without a display
The version of the Berker B.IQ 3-gang push-button sensor with integrated room temperature controller and display comes with its own scene module. Whether the integrated display is still up to date or not is something that everyone has to decide for themselves. The illuminated blue KNX bus LED in the middle of every Berker B.IQ still looks really cool.
Then as now, the white illuminated status LEDs are an eye-catcher – could Gira have found inspiration here for its brand new push-button sensor 4?
Conclusion: upper class with design affinity
Anyone who wants a classy KNX Smart Home (see also Smart Home Villa) in the portfolio could come across the Berker B.IQ in the stainless steel version. It can still be retrofitted today. It is very suitable for both new builds and renovations. For the long time that the Berker has been on the market, it is a real bargain today: The 3-gang stainless steel version of the Berker B.IQ with display costs just under 250 euros, without display it is only 150 euros. This means that the range of functions can be less extensive.
Berker B.IQ push-button sensor 3-gang comfort rating
Overall rating: 1st place (mid-range)
2nd place: Gira push-button sensor 4 Komfort
The company Gira from Radevormwald near Cologne is a veteran in the KNX push-button market and has been building KNX switches for almost 30 years. Compared to its predecessor – the outdated and not so attractive Gira push-button sensor 3 – the brand new Gira push-button sensor 4 Komfort is worlds apart. Everything is new and looks much more sophisticated: the stainless steel version has entered the upper class of KNX push-buttons and really impressed us. A hammer!
The right sensors are also on board, saving both budget and additional wall outlets per room. With the new KNX push-button, Gira is really looking to the future and has invested a lot of time in the development of hardware and software. Great!
We have published a detailed test of the Gira push-button sensor 4 Komfort in the article “Test: Gira push-button sensor 4 Comfort – best KNX push-button in the segment? LEDs & humidity sensor ” published.
Quality and workmanship: Very good
At first glance, the workmanship and quality impression is very good, at second glance the very good and harmoniously illuminated LEDs for status display are striking. This looks even better than the Berker B.IQ, where Gira in Radevormwald seems to have analyzed the market in detail. It could even be that the developers have carefully analyzed the competition and taken inspiration from it. Bull’s eye!
Functions: Everything architects and builders like
The quality (and color rendering) of the colored status LEDsof the Gira push-button sensor 4 Komfort, which can also be used as night light LEDs, is unique on the KNX push-button market. There are scenes in the push-button that can be called up or changed. Highlights are the integrated sensors for measuring the room temperature and room humidity – the latter in turn saves additional KNX components and drilling work in the wall.
The Gira push-button sensor 4 Komfort can be configured as an 8-gang single push-button or as a 4-gang rocker (highly recommended). If you want to control fewer functions in the room, the push-button sensor 4 is also available as a 2-gang version. Also an absolute eye-catcher!
Depending on the features, the Gira push-button sensor 4 costs between EUR 250 and EUR 400 (comfort version with stainless steel as in our test).
Conclusion: functional diversity and top workmanship
New-build customers with regard to smart homes who want a KNX push-button that impresses with its good workmanship, attractive LED status lights and wide range of functions as well as a very good price/performance ratio. The Gira push-button sensor 4 Komfort in the stainless steel version is not a bargain, nor does it want to be with these features. If you want something really classy, you can also have the push-button functions engraved or choose the bronze version.
The stainless steel comfort version (top model) shown and tested by us comes in at a good 380 euros and is therefore slowly moving closer to Basalte. This is certainly what Gira wanted.
Gira push-button sensor 4 comfort stainless steel Rating
Overall rating: 2nd place (mid-range)
3rd place: Berker Series 1930 R.classic
The Berker Series 1930 R.classic is actually a very ordinary rotary switch for conventional electrical installations, which are no longer in keeping with the times. As it is often requested by design-savvy clients and especially architects to equip old Art Nouveau villas, a solution had to be found to integrate it into the KNX system. And there is one!
Of course, this did not come from Berker itself (now unfortunately part of Hager) but is designed and implemented by people like us. The Berker Series 1930 switch is available as a“rotary switch with two different outputs and zero position“, which can be “converted” into a simple KNX push-button via a connected KNX push-button interface. This means, for example, that a villa from the 1900s can be completely equipped with a KNX system including the 1930s look of the Berker S1930.
Given the continuing sales success of the 1930 series, why Berker doesn’t finally build its own KNX push-button remains incomprehensible to us all. The matching KNX push-button interface is best taken from Theben, which is easiest to configure in ETS 5/6.
And what about the costs? For just under 220 euros, the building owner receives a good visual integration of the retro push-button with KNX connection – without a temperature sensor and extensive functions, as offered by the other KNX push-buttons in this environment.
Berker Series 1930 R.classic with Theben KNX rating
Overall rating: 3rd place (mid-range)
KNX push-buttons from 350 euros: High-end class
1st place: Basalte Sentido Quad
The new Basalte Sentido V4 has been available since October 2023 and replaces the Sentido V3, which was available for 8 years. Externally, the new one is indistinguishable from the previously available Basalte Sentido, and the 12 different material and color variants remain completely the same.
There was a major technical update under the hood of the Sentido push button:
1. the heating controller has been adapted and further developed
2. the built-in temperature sensor has been improved
3. there are now feedback objects for the multi-touch functions
4. the ETS programming has been simplified somewhat
5. The scene controller has been adapted
Basalte specifies the new Sentido V4 with a KNX current consumption of 11 mA, which is quite low considering the functions.
As before, the Basalte Sentido (available as a 2-gang and 4-gang push-button) clearly belongs in the extremely high class of KNX push-buttons with its elegant appearance, superior workmanship and variety of materials.
It comes from Belgium and is also manufactured there. The price of the Sentido in the white satin version – made of aluminum, of course – starts at just under 495 euros including German VAT. Prices have been raised several times by Basalte in 2022, but this doesn’t just affect the Sentido in particular. The new Basalte Sentido V4 costs the same as the “old” Sentido V3.
In the video article “KNX push-buttons for home control – material check” we present the Basalte KNX push-buttons with their finest metal combinations for the right ambience.
Quality and workmanship: nothing more is possible
The Basalte Sentido KNX push-button is one of the best money can buy on the market. When wall-mounted, the push-button is completely flush with the wall. The fitting tolerances here are smaller than with any other KNX switch on the market. If this is not so important to you – please choose another candidate from our test field.
Functions: Unique scene sequencer
The multi-touch function and the scene sequencer with LED pulsers in the background should be emphasized. Looks cool and good, and is not available in this form from any other KNX push-button on the market.
Conclusion: Luxury class
If you are in the process of planning your high-end smart home on a KNX basis, you should definitely include the Basalte Sentido V4 on your shortlist. The same applies to those who are currently planning a villa or penthouse apartment – see also our article “What is a smart home luxury villa?“ – to implement.
As the Basalte Sentido V4 could be intended for the next 20 to 30 years, it is a good investment in materials and technology. And it looks really good – at just under 495 euros each, depending on the equipment.
Basalte Sentido Quad rating
Overall ranking: 1st place (high-end class)
2nd place: Basalte Fibonacci Quad
Compared to the Basalte Sentido, the Basalte Fibonacci is exactly 50 percent larger (in terms of surface area) and offers the same range of functions and materials. The name goes back to the mathematician Leonardo Fibonacci from the Middle Ages, who studied the “golden ratio” and aesthetic positioning.
The background: Basalte wants to use the name to appeal to architects in particular who have never heard of “Smart Home” or “KNX push-buttons”. That makes sense, because most architects still have no idea what a “smart home” or“KNX in house building” could be. We have a lot of contact with architects, so let’s hope for the best in 2024!
The price of the Basalte Fibonacci is higher than that of the smaller Basalte Sentido, but in our opinion it is worth including the Fibonacci on your shortlist, especially when it comes to a smart home villa.
Quality and workmanship: Absolutely top
The Basalte Fibonacci KNX push-button is manufactured in the same factory as the Basalte Sentido – in Belgium. The push-button is available in 12 different material versions and both as a 2-gang and 4-gang KNX push-button. If you can’t decide, you can buy several surfaces over time and simply swap them out. It looks and feels good.
Functions: Very well equipped
As with the Basalte Sentido, the Basalte Fibonacci also features the multi-touch function and the scene sequencer with pulsating LED in the background. This is particularly impressive when guests are present. The highlight: the individually engraved switching functions, which are illuminated by LED.
This means that the buttons should only be assigned once and correctly. The room temperature can be measured and controlled via the integrated sensor – everything else happens in the actuator anyway. Oh yes, just in case, the Basalte Fibonacci also has an integrated heating controller and can also offer a cooling function (air conditioning).
Not forgetting the cool proximity function, which automatically activates the backlight so that the Basalte Fibonacci can remain dark the rest of the time. The night light function, which can be set to 3 brightness levels and 10 different color tones, should also be mentioned at this point.
Conclusion: Luxury class - perfect for smart home villa
The Basalte Fibonacci is clearly aimed at luxury customers with an affinity for design. These are executives from the upper middle class as well as successful self-employed people and top entrepreneurs. What does the property look like? It could be an old villa that has been given a new lease of life as a KNX Smart Home. Or it could be an individual house for clients who really value the highest quality of workmanship and materials.
At least 600 euros must be invested in the Basalte Fibonacci Quad, which is always visible and perceptible to residents or guests. It’s like getting into a current Mercedes S-Class, as a combustion engine of course. Depending on the material variant selected – there are 12 to choose from – the Basalte Fibonacci costs a few euros more.
The Basalte Fibonacci owes its soaring price to the multiple price increases of the past two years. Let’s hope for the best that prices remain constant in 2024.
Basalte Sentido Fibonacci Quad rating
Overall ranking: 2nd place (high-end class)
3rd place: Basalte Chopin
The Basalte Chopin is clearly aimed at the luxury segment. It finds its way into time-honored villas, which are networked with KNX and brought up to the latest technical standards, or into high-quality new-build houses of the upper class.
The Basalte Chopin plays a special role among all KNX push-buttons: The operation and button shape are very reminiscent of a piano. We have never seen anything like it in the KNX environment in the past 18 years! Added to this are the almost limitless
Options for individualization in the choice of shape, design (single/double, lengthwise/crosswise, etc.) and choice of material: As with the other Basalte KNX push-buttons (Basalte Sentido, Fibonacci, Deseo), the Basalte Chopin can be configured in 12 different real metal variants. These include very elegant combinations in Fer Forge (hammer finish) or shiny brass (gold) with a heavy metal plate made of bronze, brushed aluminum or copper rose.
Quality and workmanship: High material quality and fit
The Basalte Chopin has been undergoing practical testing for some time now. We also took the opportunity to test the functions in combination with various metal surfaces and colors. The “keyboard touch” – as it should be described in any case – is very defined and can be triggered precisely and with slight resistance in both directions. Fingerprints are not visible and the material appearance can be described as extremely high quality.
The fitting tolerances are in the low tenths of a millimeter range and convince even very demanding natures who are quick to grumble about small details.
Functions: Temperature controller and status LEDs
What is not visible at first glance: The Basalte Chopin offers 10 button functions via two piano rockers, provides optional illuminated status feedback in freely selectable colors and has a complete temperature controller for KNX heating control integrated. Whether the latter is really still useful and needed in this day and age is something everyone has to decide for themselves.
If that’s not enough, you can parameterize the Basalte Chopin in the KNX ETS software so that the cool scene sequencer (known from the Basalte Sentido) also offers four different colour codes in succession for selection and selection. This turns the inconspicuous little mini-piano on the wall into a room control system that only larger KNX push-buttons with many more operating elements can offer.
Conclusion: high-end luxury with special status
The Basalte Chopin goes its own way in the high-end luxury class, with its piano-shaped keys, material appearance, almost limitless customization options and technical features currently unrivalled on the market. Anyone who attaches great importance to interior design, colors and ambience in any room should shortlist the Basalte Chopin. In a time-honored smart home villa the Basalte Chopin cuts a fine figure. The customization options are perfect, as are the underlying KNX technology and functionality.
The equipment/individualization starts at just under 400 euros with Basalte Chopin and ends at just under 600 euros.

Overall ranking: 3rd place (high-end class)
4th place: Enertex MeTa KNX Premium
A large black KNX push-button with display and rockers made of brushed aluminum – in our black version. This is the Enertex MeTa KNX Premium, where “MeTa” stands for an additional “menu button” in the name, which no other provider on the market can offer.
Enertex is a German company based in Forchheim in Franconia (part of Bavaria). The KNX push-button is available in three versions: Starter, which is more of a budget version, Standard, which is the more recommendable of the two, and the Premium version, which we would recommend.
We have published a detailed test of the Enertex MeTa KNX Premium in the article “Comparison of top KNX push-buttons: Enertex MeTa Premium vs. standard” published.
Quality and workmanship: Very good
All versions of the Enertex MeTa KNX push-button are very well made and differ in terms of the number of buttons, the choice of materials and the range of functions. We like the black premium version made of brushed aluminum and the top hit: the real gold version on a brass base, which also cuts a fine figure in chic German homes.
Functions: No one offers more
Starting with the Enertex MeTa KNX Premium, there are many functions in a single push-button: starting with the heating controller, through the integrated sensors for light brightness, humidity and room temperature, to the binary input. The latter can be used, for example, to query window contacts for an alarm function.
The real highlight of the Enertex MeTa KNX Premium: All rockers/buttons can be labeled electronically in the KNX ETS5/6 software. The music tracks of a multi-room audio system can also be displayed on the Enertex MeTa via the KNX bus.
In addition to displaying the button assignments, there is a large display above the rockers that shows the ventilation system status, room temperature, etc.
Of course, this range of functions also includes definable scenes. Whether these are needed in conjunction with a modern KNX visualization server must be decided individually.
Conclusion: functional giant with luxury tendencies
Enertex is something for special customers who like something special but don’t want to spend a fortune. Nevertheless, the price scale extends almost to the highest segment (where Basalte is located) for the real gold version of the Enertex MeTa KNX Premium. Here you have to invest a little more than six bills including German VAT. Nevertheless, the premium version of the MeTa clearly belongs to the upper class of KNX push-buttons and makes a real impression – for just under 420 euros.
The unique real gold version costs 600 euros and has long since found its way into suburban villas in southern Germany and Switzerland. It can also be cheaper: The Enertex MeTa Standard, which we also tested and used, is available for just under 300 euros.
Enertex MeTa Premium rating
Overall ranking: 4th place (high-end class)
5th place: Ekinex Signum
At first glance, the Ekinex Signum shows: I am not a German product, I come from Italy. The design, choice of materials, color scheme and display are harmoniously coordinated and make the Ekinex Signum a real eye-catcher! For us, it is the Maserati of KNX push-buttons! Why this is the case can be clearly seen in the following lines. The Italian was only really launched on the market in the course of 2023 and is therefore one of the really hot newcomers in the upmarket segment of KNX push-buttons.
The Ekinex Signum is actually something of a hybrid: it has an integrated touch panel (IPS panel) and could easily be categorized as a classic KNX touch panel. However, it lacks the full-format display size and your POE network connection. And that’s a good thing, because the Ekinex Signum is a great KNX push-button with a very individual design and a very fine character set that no other KNX push-button has.
Some special highlights of the Ekinex Signum are: The vibration/acoustic feedback of the touchscreen when touching and swiping, you could also call it force feedback, and the Bluetooth connection for the smartphone.
Quality and workmanship: Scratch-resistant surface - very good
The name “Signum” stood for an award in ancient Rome. The surface quality of the KNX push-button milled from aluminum is very good and the plastic parts of the housing of the electronic unit are also convincing.
We can state quite clearly: The Ekinex Signum is positioned in the luxury class, i.e. in the world of new-build villas, smart home villas and high-quality existing buildings that are due for renovation.
Functions: Cell phone configuration superfluous
Like only very few candidates in this major comparison of the best KNX push-buttons, the Ekinex Signum offers a proximity function: it only switches its touch panel on when an operating hand approaches. This allows the push-button to remain nicely in the background and let the room and its backgrounds take effect.
What we found in our test: The Ekinex Signum icons are best set up using the ETS software, where all the parameterization and configuration takes place anyway. It also works via Bluetooth LE in conjunction with a smartphone (Apple/Android). Although no ETS software is then required afterwards (after teaching with the ETS software), the definition of characters for icons and button functions is less convenient on the cell phone.
A total of three different menu pages can be created and thus 12 different switching functions can be stored. The Ekinex Signum still has a real room thermostat/room temperature controller, which has become increasingly rare even in the high-end KNX push-button segment.
And of course this can be switched off and the function taken over by a KNX heating actuator. In this case, only the integrated room temperature sensor is used.
The Ekinex Signum’s ability to select audio streams from Amazon, Spotify or Apple Music at the touch of a button is interesting in combination with a multi-room audio system, which is now a standard feature in many new-build homes.
The Ekinex Signum has its own template pages for this purpose, which no other KNX push-button can offer in this form.
Conclusion: Luxury class with Italian flair
So what is the verdict on the Ekinex Signum, the top model from the Italian manufacturer? For just under 460 euros including German VAT, you get a KNX push-button that impresses with its special appearance, wide range of functions and an IPS touch panel. In terms of price, the Ekinex Signum is positioned between the German Gira push-button sensor 4 comfort stainless steel and the Belgian Basalte Sentido Quad in the white “basic version”.
If you like or even drive Italian cars such as Maserati, value a special ambience and are also planning a smart home villa or chic apartment, the Ekinex Signum is worth considering. If you are looking for pure functionality and sober features, you should take a look at the other candidates in this comparison test.
Ekinex Signum rating
Overall ranking: 5th place (high-end class)
6th place: Basalte Deseo RTR
To get straight to the point: There is no KNX push-button on the market that is more expensive than the Basalte Deseo with RTR – regardless of which version we now specify in more detail. The “RTR” stands for room temperature controller, which many push-buttons also offer and which only cost a fraction of the price in comparison. BUT: Its exclusivity in terms of material appearance, design, color scheme and operating ergonomics can be seen and sensed from a distance. But what is the Deseo actually about? It’s about pure luxury that no other KNX push-button is able to exude!
At the same time, we have to point out that the Basalte Deseo is a little outdated and the technical development of the push button dates back to 2014.
Depending on the choice of material, the price of the Basalte Deseo RTR scratches the four-digit euro mark, without giving detailed prices here. And yes, there are estates where many of these buttons are used – at just under 1000 euros each.

KNX push-button for special applications
1st place: Enertex ProxyTouch
Enertex is a Bavarian-Franconian company that specializes in the development and production of high-quality KNX components. At Enertex, the boss himself is still actively involved in development. The Enertex ProxyTouch has a unique position in the global KNX push-button market: it is the only KNX push-button that can be placed behind walls such as tiles or drywall and reacts to hand swipe gestures. Swipe gestures in the KNX environment? Yes, that’s right, even on a smooth (shower) wall with or without tiles.
We have published a detailed test of the Enertex ProxyTouch in the article “KNX push-button completely invisible: Enertex ProxyTouch – push-button behind the wall” published.
Quality and workmanship: Very good and durable
Although the Enertex ProxyTouch is alone on the global market for gesture control, the Bavarian company from Forchheim keeps its sales price down to earth: the well-made KNX push-button costs around 250 euros, a good price considering the great features and quality on offer. Chapeau!
Functions: Gesture control with sound output
What else is there to say: No other manufacturer can offer gesture control for KNX push-buttons. There is also an acoustic feedback when a switching function is triggered, which can also be “parameterized away” in the KNX ETS software. Of course, the Enertex ProxyTouch can also be parameterized as an “invisible KNX push-button” without gesture functions.
Conclusion: For high-quality bathrooms and secret safes
The invisible KNX push-button Enertex ProxyTouch appeals to a very special clientele: People with larger bathrooms, where the ProxyTouch is installed behind chic tiles and attracts attention with wet hands using a wiping gesture. Or builders who have hidden a safe behind a painting on the wall. When a certain spot on the wall is touched, the painting moves to the side and gives access to the safe. There are other possible applications, but let’s leave it at these practical examples.
At a price of 250 euros, there is no comparable range of invisible KNX push-buttons on the market. It is part of our standard conceptual repertoire for smart networked new-build homes.
2nd place: Jung F50 push-button sensor
The Jung F50 push-button sensor differs from the Jung F40 in the different button arrangement and the optional display in the middle. If you need a status display and are in the Jung design line, the Jung F50 could be a good choice.
3rd place: Jung LS Touch - hot new arrival 2023
The Jung LS Touch was presented at the Light & Building trade fair in Frankfurt at the end of 2022 and at first glance looks like a more sophisticated version of the MDT Glastaster II smart. Jung has probably taken inspiration from its competitor in terms of development and design. In terms of price, the Jung LS Touch is positioned in the luxury league above 450 euros. That is, of course, quite an announcement! We hope to be able to examine and present the Jung LS Touch and present it in more detail.
Positioning of KNX push-buttons Manufacturer: MDT to Basalte
The graphic below provides an overview of the positioning of the individual brands/manufacturers on the KNX push-button market. It is based on our many years of practical experience and our own assessment. There are 83 different manufacturers on the market offering just over 1100 KNX push-buttons. That’s an average of 13 different push-buttons/variants per manufacturer!
The chart below lists the most relevant manufacturers of KNX push-buttons for German-speaking countries (DACH = Germany, Austria and Switzerland). There are a number of other manufacturers, but we do not consider them in terms of availability in Europe and quality/design.
The benchmark for all KNX push-buttons is, on the one hand, the technical equipment offered, which is expressed in the range of functions and increasingly integrated sensors. On the other hand, a high-quality look and feel is at least as important for many building owners.
After all, no other smart home system in the world offers such a wide range of colors, materials, surface haptics and designs. And the trend is rising! While Basalte in particular and now also Gira and Jung (but not exclusively) tend to position themselves in the high-end segment, MDT, Theben and Busch-Jaeger, for example, appeal to the broader market of new KNX smart homes.
Note: The graphic above shows a section of the market for KNX switches and KNX push-buttons.
What do all KNX switches have in common?
The bus coupler is always integrated into the newer and current KNX push-buttons. This was not the case in the past (until around 2010) and the bus coupling unit had to be purchased for an additional 35 to 45 euros per push-button. Here the market has clearly developed in favor of the building owners, today there are many more KNX components for significantly less money than 10 years ago!
As a result, construction costs continue to rise due to the constant increase in fixtures and fittings and the need for greater living comfort.
If we were to equip a house today as we did in 2015, the costs for the KNX push-buttons alone would be significantly lower. Today, there is much more equipment for less money.

What does a KNX push-button cost? Where do the price differences come from?
This is a wide price range for KNX push-buttons. Depending on the material (metal, plastic, wood), the surface feel and the functions/equipment (additional display and number of sensors), the price varies between approx. 80 euros and over 1,000 euros. The switches we have tested here in practice and used for over 16 years are definitely recommended – with their respective strengths and weaknesses.
Then there are the different sales channels. Some manufacturers, such as MDT, sell directly to builders via online retailers, thus saving themselves the entire sales force. This leaves the electrician, who usually carries out the electrical installation in a house, with less profit margin on the material. This is because the builder/end customer pays the same price as the electrician.
Other traditional German manufacturers such as Gira, Jung, Busch-Jaeger and Theben sell their KNX push-buttons in the three-stage system via wholesalers and have their own regional representatives with sales representatives throughout Germany. Large online retailers with their own warehouse now buy directly from the manufacturers mentioned and thus operate in two-tier sales. Nobody really wants to admit this, but it is a development that can no longer be stopped.
Manufacturers in the high-end segment, such as Basalte from Belgium, sell their KNX push-buttons exclusively via selected Basalte Pro-Partnerswho also have the relevant practical know-how and experience in dealing with demanding customers.
Which KNX push-button material is right for me?
When choosing the right KNX push-button material, there is a correlation between long-term quality and price: While KNX push-buttons made of plastic – regardless of the manufacturer – are offered fairly cheaply on the market, the stainless steel versions cost significantly more and are very durable.
Versions made of aluminum or glass are slightly cheaper. KNX push-buttons with a leather surface, which are currently only available with the Basalte Enzo (black or white leather), are still exotic. Gira is taking a new approach with the optional use of linoleum surfaces.
And what is meant by long-term quality? In the case of the plastic KNX push-button, the color will change over the years and no longer look quite as fresh as on the first day. However, this has no effect on the functions. With normal use, a service life of 25 to 30 years can easily be expected. There is no longer customer experience, as the first KNX Smart Homes date from 1998 to 2000.
KNX push-buttons with encryption: Why KNX Secure?
The KNX push-buttons we present here, most of which have been extensively tested in practice, are not yet all equipped with encryption. “KNX Secure” available. So that the encryption (AES128 algorithm) works properly and can be used in the KNX network , at least two participants – usually KNX push-buttons and the corresponding KNX actuator – must support the new KNX Secure encryption standard.
This means that communication between the KNX push-button and actuator cannot be manipulated or interpreted.
Is that possible: KNX push-buttons outdoors?
A common question for most building owners: Can I place KNX push-buttons outdoors, such as in the garden, patio, pool, tree house or garage? The answer is very clear: No! KNX push-buttons should only be placed inside the house, if only to protect them against tampering and environmental influences such as moisture, sunlight or frost.
An exception could be a separate KNX line for a special KNX push-button that is located in a “secret” position. If, as expected, an external attacker gains access to the KNX system via the external KNX push-button, the connection on the separate KNX line should always be encrypted (KNX Secure) and filtered.
How many KNX push-buttons in a house?
In the conception and KNX planning phase of a house, the question of the total number of KNX push-buttons required in a building is clarified. We often use at least one KNX push-button per room, although this always depends on the individual situation and the size of the room.
For larger rooms of 20 square meters or more (e.g. in the kitchen and living/dining area), one push-button is usually no longer sufficient. Smaller rooms such as toilets or storage rooms can do without KNX push-buttons altogether.
At what height is a KNX push-button mounted?
We are often asked this question during the design and KNX electrical planning phase with building owners: At what height should a KNX push-button be mounted in the room? What is the recommended mounting height? In principle, there is no difference to a conventional switch: the installation height should be between 1.20 and 1.30 meters from the top edge of the finished floor (abbreviation in CAD architect plans often: “OK FFB”).
The aim is to ensure that all residents can easily reach the KNX push-button for operation and, if available, can easily read the display. If there are children in the house, they should also be able to operate the KNX switches.
A special situation arises when KNX push-buttons are installed in cabinets (e.g. kitchen, hallway or bathroom). In this case, the installation height may differ from the above recommendation and be completely individual. In the bedroom, for example, KNX push-buttons may be placed at a height of 0.6 meters (top of FFB) on the bed or directly in the built-in furniture.
Top 5 KNX push-buttons from 17 years of building owner practice
In the video above, we present the “Top 5 KNX push-buttons” of the past 17 years from our point of view and experience – read more in the article “Smartest Home Story“, which is about our own KNX history and story. And an important note: These Top 5 KNX switches are a subset of the “Top 30 Longlist” of our overview, which is constantly kept up to date.
Conclusion
First of all: there is no single top winner in all price and performance categories. It is always necessary to consider the respective price segment and the target group – from reduced single-family homes to smart home luxury villas.
When it comes to the best material quality and functional features, the Basalte Sentido is clearly in first place in the high-end class (from 350 euros). Here, only the more expensive Basalte Fibonacci from the same company can hold a candle to it and even surpass it in terms of features. The colorful scene sequencer of the Basalte Sentido V4, which was renewed at the beginning of 2024, is and remains unique, as is the extremely clean finish of the 12 different real metal variants. Many competitors are looking at this button and trying to copy it, but so far it remains the undisputed leader.

Who wants the best price/performance ratio in the entry-level class up to 150 euros, the MDT Glastaster II smart is still the best advice. This KNX push-button has ensured that even “small” detached houses can be equipped as KNX houses throughout the D-A-CH market and beyond, with a great deal of input from the building owners themselves. For those who don’t like the look and playful symbolism of the MDT, the second-placed KNX Theben iON 108 push-button with display.
The Theben iON 108 from the Black Forest even has an integrated room temperature controller, which is missing from the first-placed MDT Glastaster II smart. With its debut iON 104/108 in 2019, Theben has launched a price hit on the market that is at least visually similar to the KNX luxury push-button Basalte Deseo – which costs many times more. Like MDT, Theben has also integrated a simple display into its entry-level iON 108 push-button, which can be individually parameterized.

There are many manufacturers in the mid-range up to 250 euros, especially German ones, although the really “old” Berker B.IQ push-button sensor 3-gang stainless steel still “holds” first place. Why is that? On the one hand, the Berker B.IQ push-button sensor a very high build quality with its stainless steel buttons. And secondly, we got to know it as a test candidate in the 17-year endurance test in a separate property, which offers a completely outdated software interface (as a plug-in for ETS5/6), but is still suitable for operating large rooms in chic smart home villas – architectural style: glass-concrete-metal.
Those who find the Berker B.IQ push-button sensor too outdated can opt for the second-placed model in the mid-range, the Gira push-button sensor 4 Komfort with stainless steel rockers. The latter has recently almost left the mid-range segment in terms of price and actually already belongs to the high-end class. This is because the Gira push-button sensor 4 Komfort quickly reaches 350 euros. There is no integrated room temperature controller for this – regardless of the variant. A message to Gira: You are not yet at the level of Basalte, even if the price is almost in the same region! So stay tuned and keep up the good work!

In addition to the individual segments/classes, there is also the “Class of KNX push-buttons for special applications”. Right at the top for us is the Enertex ProxyTouchwhich can also be used as invisible KNX button can be described as a “swipe”. Placed behind (drywall) walls or (kitchen, marble, real stone) worktops, it can perform not only normal switching functions but also “swipe functions” (swipe gestures), which are not available anywhere else on the global KNX push-button market.
Our final conclusion: nowhere is there as much choice when it comes to switches for smart homes as with KNX push-buttons. Both the young beginner with a terraced house or condominium and the successful self-employed person / entrepreneur with a magnificent high-end villa on a lavish estate are equally well served. In addition, there is the outlook and look back over decades, where KNX push-buttons exist and existed 30 years ago.
