What is KNX?

KNX is a worldwide Standard for Home & Building Automation.

KNX is the only worldwide standard for home and building automation allowing complete building control including Lighting, HVAC, Shading, Security, Energy and Audio/Visual and more. KNX is a managed open-source and non-proprietary protocol with KNX partners globally.

KNX is a BUS wired system operating on SELV with an advanced topology making it robust, secure, versatile and scalable for deployment across Residential, Commercial, Industrial and Maritime applications.

KNX is often deployed in the residential sector due to its immense capabilities and usual design led approach. For more information of KNX Smart Home, we suggest you follow the link below:

Of course, as mentioned, KNX offers opportunities for much larger properties and even cities! Some of the core features that make KNX unique include:

  • Open Source & Non-Proprietary Nature

  • Decentralised Shared Intelligence approach

You can view KNX Project Case Studies via the KNX Association website.

The topology of KNX is traditionally based on the KNX TP1 twisted pair cable which allows connection of up to 256 devices per line and 57,375 KNX devices in a single project. The cable can be run up to 1000M in a single line with up to 350M between devices. The cable is SELV and can be run directly alongside mains power.

KNX has it’s own engineering tool known as ‘ETS‘ in which all KNX devices conform to ensuring true interoperability.

KNX also has the ability to interface many other protocols/standards including: BACNET, MODBUS, M-BUS, Serial, DALI, DMX and so on.
