KNX Standard


KNX is a global and open standard and remains the core of our developments. With a history of over 30 years, which we as a company have been supporting and actively participating in for over 20 years, KNX is still the gold standard in smart buildings. Whether in private or commercial construction, KNX offers a powerful system that has been specially developed for building control.

Based on the fundamental specification from the EIB times, the system has been continuously developed and expanded. Besides the classic KNX twisted pair bus, the wireless medium KNX RF is also available . In addition, KNX IP is a fully-fledged medium in KNX and is not only used for interfaces or as a fast backbone.

The strength of the KNX protocol is demonstrated not least by the introduction of KNX Security. Although it was quite a challenge to fully protect the complex KNX protocol, it was possible to develop a comprehensive solution for all media with KNX Data Security. In addition, KNX IP Security protects IP communication within the KNX system, even if the telegrams on TP or RF are not encrypted.
