There were presentations from the various startups, plus Cascoda CEO, Bruno Johnson on fast device development using the open-source KNX IoT software stack and Cascoda’s Development Kit for KNX IoT Point API. Lorenzo Piro, EMEA Business Director for Aruba, a Hewlett Packard Enterprise company, explained the importance of IP infrastructure in homes and buildings to support KNX, as a leading technology in interoperability over IP. The event was wrapped up by Jesus Arias, who invited delegates to join the KNX IoTech After Party.

KNX addressing the world

In his inspiring keynote ‘The future of IoT in Home and building automation’, KNX Association CEO and Spokesman, Heinz Lux, explained the three keys advantages of KNX IoT technology (aka KNX IoTech); namely connectivity, interoperability and communication. He pointed out that control systems such as Google Nest, Apple HomeKit, Amazon Alexa and Philips Hue are separate systems and difficult to bring together – which is where KNX, as a worldwide standard, is the natural solution, with over 30 years of experience, 500 manufacturers cooperating towards the same goal and over 8000 certified compatible devices.

Heinz went on to explain that for the IoT, rather than routers and gateways, we need to use a ‘grammar’ between devices, i.e. semantic communication, and that this can be done through the KNX programming software, ETS. He concluded by stating that KNX IoTech is going to revolutionise the building control sector, that ETS has everything we need for the IoT, and that KNX is five years ahead of any smart home/smart building technology.

KNX Marketing Manager, Casto Cañavate, provided a thought-provoking presentation entitled ‘Setting up the Future for the IoT industry in Home and Building Automation’. He started off by pointing out how the adoption of the smart speaker and the smart thermostat has dramatically increased awareness of the potential for homes to be smart, and how the IoT promises to connect all devices together in one big eco system, but currently, the market is hyper-fragmented.

He also raised a number of questions about security, data sharing, whether devices are truly cloud-based or not, open or closed, whether they can be updated, whether they have a long life cycle and whether they are interoperable. He gave an example of how adding one third-party product to a control system is easy, adding a second might be fine if they are truly interoperable, but adding a third or more could start to get more complicated, and so on.

Casto then went on to explain how KNX answers all of these points positively, how security is part of KNX’s design, how the KNX Association has embraced the IoT and wants to maintain the highest standards, and how KNX IoT has been introduced as an open source software stack that is freely available on GitLab. This puts it in a prime position to harness the energy of large corporations and startups to use the IoT to make homes and buildings smarter and more sustainable through energy management.


The IOTSWC was a great platform for the KNX Association to promote KNX IoTech. It is showing inspired leadership by providing the free-of-charge open-source KNX IoT software stack, and offering help to new startups on how to get started.

My takeaway from the event was that until now, I had never truly appreciated just what an incredible achievement KNX is. From an engineering point of view, KNX has always made sense to me as a worldwide standard and as a robust, decentralised system, but when you think about it, how amazing it is that nobody investing in KNX is abandoned – at the heart of KNX is backwards compatibility, right to the start of KNX over 30 years ago! Now that’s what I call a long life cycle. Should you need to add or replace a product, there are now over 8000 different KNX devices that have gone through the strict certification process, that are guaranteed to work with legacy and new systems. Of what other technology could you say the same?

And managing to get upwards of 500 manufacturers to put egos and rivalries aside and work for the common good, not just over a handful of years but over decades, is a phenomenal achievement, let alone setting up more than 500 training centres and getting 100,000 KNX professionals trained.

The IoT promises a lot, but demands interoperability between systems that is sustainable. KNX is addressing this with its trademark professionalism and energy. These are not empty words – KNX has a proven track record and the right culture to provide a framework for the IoT long into the future, whilst maintaining the highest of standards.
