The second KNXperience took place online over three days from 28-30 September 2021. Yasmin Hashmi picks highlights from the conference presentations.
Opening Speech: KNX is Innovation, Innovation is KNX
Franz Kammerl, President, KNX Association, opened proceedings by saying how innovation is the DNA of KNX. He then announced key innovations, including the highlight of KNXperience 2021 – the launch of the new generation ETS6, which he described as the only software tool on the market that combines planning, designing, commissioning and diagnostics. He added that a big step this year was the approval and release of the vendor-independent KNX IoT third-party API standard, and that the first KNX IoT devices are expected very soon. Furthermore, the KNX Point API, KNX Association’s IP field bus communication solution, will soon be announced too. He noted, “My personal main KNX target is to create solutions and to build a more sustainable future for smart living”, and concluded that “energy management with KNX is best placed to make use of digital infrastructures for the transition to emission-free energy.”
Keynote: ETS – Yesterday, Today, Tomorrow
Heinz Lux, CEO, KNX Association, explained that in order to satisfy the latest technical, economic and global demands, the KNX Association has now completely redesigned its Engineering Tool Software (ETS) and added numerous functions. As he put it, “ETS6 makes building automation with KNX even smarter, more secure and more open than ever, through numerous innovations.” He pointed out that ETS today is currently available in 19 languages and 190 countries, can be used for the installation of more than 8000 KNX-certified devices from more than 500 different manufacturers, and is being used in over 10 million projects by KNX system integrators, all over the world. As a surprise guest, Lux interviewed the 100,000th certified KNX Partner, Joan Emo from Spain, who explained that he was first introduced to KNX in school. Lux then formally launched ETS6 as “One tool. All you need.”
ETS6 Professional – Smart, Secure, Open
Hailing ETS6 “the most important KNX software tool to date”, Vassilios Lourdas, Tools Leader, KNX Association, went on to describe ETS6 Professional as far more than a new version, “It is smart, secure and open, and available today.” He explained its numerous innovations, including an improved user experience through an optimised user interface, and fully-implemented KNX secure functions and security proxy functionality. Lourdas provided a useful overview of what we can expect from the new software, including how ETS6 fully taps the potential of KNX IoT, with the option of exporting all relevant semantic data to the KNX IoT third-party API, making KNX systems even more interoperable with any third-party client.
KNX Energy Management – realisation of the prEN50491-12-2 in KNX Classic
The target audience for this presentation by Joost Demarest, CTO, KNX Association, was KNX product managers and developers wishing to realise KNX solutions for the upcoming EN50491-12-2 standard for home and building electronic systems (HBES) and building automation and control systems (BACS) with respect to the smart grid. Demarest explained that whilst KNX energy management concentrates mostly on collecting momentary values in a central and/or visualisation device, the prEN50491-12-2 will introduce mechanisms to allow devices to communicate their energy flexibility, i.e. to indicate what they are likely to produce or consume in the immediate foreseeable future, for improved energy management in the home or building. He discussed the different control modes defined in the prEN50491-12-2 using KNX Classic group communication, and the use of extended frames, which will also be supported in ETS6.
KNX IoT – opening up new development possibilities for existing and potential KNX Members
This was another presentation by Joost Demarest, CTO, KNX Association, that was aimed at KNX product managers and developers, this time for those wishing to extend their portfolio with KNX IoT solutions. Demarest outlined the reasons behind KNX IoT, the overall system architecture and the new development possibilities offered with KNX IoT. He went on to explain that whilst KNX Classic technology (TP, RF, KNXnet/IP) continues to be successful after more than 30 years, manufacturers from different domains often want to use alternatives to TP such as Thread. He concluded that KNX IoT extensions in the form of the 3rd Party API and the Point API facilitate this and make KNX even more attractive for industrial companies.

Outside the conference
There was so much to do and see at KNXperience 2021. In addition to the conference, two halls hosted 35 booths from KNX members and training centres, plus the opportunity to meet experts and join in Q&As, network and chat with others, and participate in games and win prizes.
Conclusion
Congratulations all round to everyone who helped make this an informative, accessible, fun and inspiring event, and to all of those who worked tirelessly on making the show’s main highlight happen – the launch of ETS6.
As KNX systems integrator, Alaeddine Bouabid, put it in the chat at the end of the show, “Thank you for this great KNXperience. Thank you for the vouchers and especially for all the information that we have been able to accumulate during these three days.”
The final words must go to Sara Fan, of KNX Marketing, who said, “I would like thank you all for being part of this event. Shout out to our event sponsors who put together great content for the show, KNX team who did a wonderful job in making it happen, and last but not least, all the participants who actively took part in the activities we organised. Together we build memories.”
