Where KNX Actually Lives: A Look at Who's Using It Around the World

People sometimes assume KNX is a niche European thing, a German protocol that a few enthusiasts run in old-money villas. I get it. That's roughly where it started. But I went through the KNX Association's own membership records this week, and the picture is bigger than most people in this industry realise, including some of my own clients.

The home turf

KNX was developed in Europe in the 1990s and the KNX Association is still based in Brussels. Germany, France and the UK remain the anchor markets, and it shows in the infrastructure: dedicated national organisations, local training centres, local-language support. If you want to see where a technology is genuinely embedded rather than just marketed, look at whether it has bothered to build local institutions in a market. KNX has had them in Western Europe for three decades.

That history matters for a practical reason. It means the component ecosystem, the training pathways and the certification standards were stress-tested in some of the most demanding building markets in the world long before anyone tried to sell you a KNX system anywhere else.

Further than you'd think

Here's what surprised me doing this research properly instead of assuming. The KNX Association currently lists 45 National Groups, and between direct national groups and shared regional ones, its recognised footprint runs to roughly 85 countries.

Asia-Pacific has its own weight class: China, Japan, South Korea, Taiwan, Hong Kong, India, Australia and New Zealand all have direct national representation, and a dedicated South East Asia group based in Kuala Lumpur covers Malaysia, Singapore, Thailand, Vietnam and Indonesia. That's not a toe in the water. That's a full regional structure.

The Middle East runs through a dedicated group based in Dubai, covering the UAE and the wider Gulf. Given how much of the current construction pipeline in that region is high-spec residential and hospitality work, a wired, brand-agnostic automation standard is a natural fit, and KNX clearly agrees, because it built the infrastructure to serve it.

The Americas have their own network too: the US and Canada each have a national group, and a Latin America group ties together Argentina, Brazil, Chile, Colombia, Mexico, Uruguay, Bolivia and Panama.

And then there's Africa, which is where this got personal. South Africa has its own KNX National Group, based right here in Johannesburg. Egypt, Morocco, Tunisia, Algeria, Sudan, Cameroon, Benin and Côte d'Ivoire all appear on the association's country list as well. I didn't go looking for that to make a point. It's just there, in the association's own records, which tells you this isn't a favour someone did for us. There's enough real activity on this continent for KNX to bother organising around it.

The scale, with a date on it

For a sense of just how much hardware this standard is running, the KNX Association's own figures from 2020, its 30th anniversary year, put the installed base at 373 million devices and a cumulative market turnover of 54.5 billion euros. I want to be upfront that this is 2020 data, not a current figure, and I couldn't find a reliably sourced updated total for 2026, so treat it as a historical anchor rather than today's number. What's current and confirmed directly from the association today is the certified device catalogue: over 8,000 certified products from more than 500 manufacturers, maintained through ETS, with a professional network the association puts at around 140,000 trained installers.

That last number is the one I actually care about day to day. It means when I spec a KNX job, I'm not locking a client into one factory's roadmap or one country's supply chain. There are 500-plus manufacturers building to the same open standard, which is exactly why I can mix Hager and Ekinex gear on the same bus without anyone needing to write custom integration code.

Where the growth conversation is happening

I'll be straight with you: most of the specific growth percentages floating around online come from market research firms whose methodology I can't verify, so I'm not going to hand you a made-up-sounding number and pretend it's solid. What I can tell you with more confidence, based on where KNX has recently stood up new national groups and where the industry press keeps pointing, is the general direction: Asia-Pacific's urban construction boom, the Gulf's hospitality and residential pipeline, and Africa's own building activity are the regions getting the most attention right now, on top of the mature European base that isn't going anywhere.

Why this matters if you're building here

For a South African client, the practical takeaway isn't the global stats. It's that KNX being a genuine international standard, with its own national group on our own soil, means parts, expertise and certification aren't dependent on one supplier staying in business or one country's import pipeline staying open. That's a real risk consideration in this market, and it's one reason I don't build on proprietary, single-brand systems.

If you're curious where a system like this fits into your own build, it's just a conversation about what the project needs.
