KNX is an open international standard for home automation and building automation, designed to ensure interoperability between devices from different manufacturers. Thanks to its decentralized and flexible architecture, KNX allows integrated control of various functions such as lighting, shutters, heating, ventilation, security, and energy management. Reliable, scalable, and compliant with European and international standards (EN 50090, ISO/IEC 14543), the KNX protocol is now one of the most widely used solutions in the residential and commercial automation sector.
