The e-magazine for KNX home & building control

Show Report Part 2: KNXperience – the products

By Yasmin Hashmi, KNXtoday.

KNXperience, which took place from 28th September to 2nd October 2020, was the first online global trade fair dedicated to KNX, organised by KNX Association. In last month’s show report, we gave an overview of the show including the conference programme, networking opportunities, the KNX Awards ceremony and competitions/prizes.

This month, we pick out some product highlights from the twenty manufacturer Member companies who supported the show with their splendid booths, videos, documentation, chat rooms and, in many cases, conference sessions.

KNXperience was supported by twenty manufacturer Members.


Among the products on show at the ABB booth for residential and commercial applications was the flush- or surface-mounting ABB Tenton three-in-one device that combines sensors for temperature, humidity and CO2 in addition to room control, in a wide range of design options.

Also on show was the ABB RoomTouch super-slim capacitive multi-control panel; and the enhanced portfolio of Combi, Standard and Professional KNX switch actuators with a large selection of currents and wide range of channels.

According to Olaf Stutzenberger, ABB Global Marketing Communication Manager, Electrification – Smart Buildings, KNXperience provided a good alternative to an IRL (In Real Life) show. “Overall the experience was very good, preparation was rather convenient and the way it operated was really good. The booth and the webinars worked well, and our customers liked this digital version, but they also miss being face to face, so perhaps it would be good to alternate face-to-face with digital in future.”


JUNG was showing a range of products, including a new generation of KNX switch and blind actuators with increased reliability, better energy efficiency and numerous new functions; and the new KNX F 10 classic-looking light switches with intelligent KNX technology that is available in push-button and rocker versions.

Commenting on the company’s experience of the show, ComfortClick’s Head of Sales, Flávio Sanches, noted, “Overall we had a good experience with this new format that is still evolving and we are excited to see the next steps in this virtual interaction. Alongside chat, I think it would be good if there were a way we could see and talk to each other when people come to visit the booth. I guess people will have to adapt to a new way of participating in exhibitions.”


Steinel was promoting its True Presence Multisensor KNX, which uses ultra-sensitive high-frequency measurement to deliver completely reliable information on human presence or absence. It reports as soon as breathing patterns are detected, and does so regardless of whether the person present is sitting, reading, resting or sleeping.

Steinel Sales Manager, Joachim de Backer.

According to Steinel’s Sales Manager Joachim de Backer, “We truly believe that True Presence technology is a revolution in the market, allowing us to define true presence and thus manage absence. With this knowledge of absence, the possibility to save energy is massive within a KNX-powered system. Furthermore, thanks to the Multisensor’s capabilities, including temperature, humidity, CO2, VOC, brightness, and air pressure sensing, we can optimise user comfort, and in current COVID-19 times, provide support for a healthier environment, detecting when air quality becomes poor and a window should be opened.”

Steinel will also be launching an updated sensor portfolio (IR QUATTRO HD-2 KNX and HF360-2 KNX) which are multisensors  for light measurement, temperature and humidity.


Theben’s Head of Technical Service & Training, Elmar Loeffler.

Theben‘s Head of Technical Service & Training, Elmar Loeffler, gave a number of fascinating conference presentations, among which was ‘Theben KNX RF Secure – extend your project without cabling but with maximum security’.

The Theben H1 RF one-way flushmounted heating actuator.

Elmar was keen to point out that the company’s flushmounted actuators and RF Secure flushmounted actuators, include a safety feature that automatically switches the actuator off in case of an overload, thus preventing the device from being damaged.

Elmar also highlighted a specific solution Theben offers when it comes to the smallest flushmount, the Theben H1 RF. “The H1 RF is equipped with two inputs, one of which can be chosen as a temperature input. By applying a small temperature probe and setting the application to controller, you have complete room heating control. Desired values can be pre-set, and with your KNX visualisation you can perform modifications according to you desires. Small and fancy!”


Among new launches was the KNX Ultra Actuator from TDE. This 24-channel device has 16A relays in 6 different adjustable blocks which can be configured as: up to 6 fan coil two-pipe control; up to 12 shutter channels; up to 24 switch outputs; or up to 24 heating outputs. It also has two universal interface channels.

In response to how he was finding KNXperience, Siemens Global Product Manager, Jorge Sanchis Barcenilla (who also gave a presentation on ‘Perfect Lighting Control with Tunable White’) replied, “I have a positive impression of the event. I liked having the opportunity to talk directly to KNX Partners from all over the world, because this is one of the things I like most about my job as Product Manager. Online is not the same as real-life contact, but it is still nice. I had the opportunity not only of presenting product, but of having interesting discussions about KNX. I will be interested to know the feedback of KNX Partners to see how they found the event.”


Among the iRidium Mobile products on show were the KNX Home Server controller with an app for iOS, Android, and Windows that is designed to facilitate the creation of a KNX smart home in one day; the KNX Integration Server controller for integrating protocols, setting any logic, and creating customised designs; KNX visualisation pro for creating user interfaces; and hardware such as the KNX IP Hub pro interface, wall-mounted iRidium Panel 7 for visualisation, iRidium ETS Remote, and KNX IP interface.

Each set contains selected KNX operating devices, sensors and actuators for automating lighting, heating, sun protection and ventilation and covers safety functions such as smoke and water leakage detection. Each set is also delivered fully-configured and addressed, so no ETS is necessary – the devices only have to be installed and will communicate with each other as soon as they are connected to the KNX bus line, which supplies them with bus and auxiliary voltage. 


Given the short notice and the logistics, KNX Association and its Members did a remarkable job of bringing together an amazing range of products, presentations and networking opportunities. No one knew for sure how this would work out – it was a new and exciting experience for everyone. Clearly, the ability to meet face-to-face was greatly missed, but in return, accessibility for everyone was greatly increased.

We are all having to adapt to a new reality, and as with IRL trade shows, virtual ones will get better if we learn from our experience. There are of course issues such as time and language differences which may pose more of a challenge, but even when life returns to near normality, KNXperience has shown that the KNX community can get together in virtual space in a very productive way, and at greatly-reduced cost in terms of money, carbon and shoe leather. So, don’t be surprised if this becomes a regular event – the genie is out of the bottle!
