What is KNX?
KNX is the world’s leading hard-wired smart home system, designed to control lighting, heating, blinds, security and many other systems throughout your home.
Unlike wireless smart devices, KNX uses a dedicated communication cable, giving you exceptional reliability, speed and long-term stability.
It works quietly in the background, day after day, without depending on your Wi-Fi or internet connection.

How KNX Works
KNX is a fully decentralised smart home system.
Instead of relying on a single hub or controller, intelligence is distributed across every device on the system. This means there is no central unit that can fail and bring your entire home to a stop.
Each switch, sensor and actuator communicates directly over its own dedicated KNX bus.
The result is a system that continues to operate even if your internet connection goes down or your Wi-Fi stops working.
Your lighting, heating, blinds, gates and other essential functions remain exactly where they belong — under your control.

Why Choose KNX?
KNX has earned its reputation as one of the most reliable smart home standards in the world.
It offers the stability of a dedicated wired installation while remaining flexible enough to work alongside modern smart home platforms.
Because KNX is an open international standard, you’re never locked into a single manufacturer, installer or ecosystem. Your system can continue to grow over time, integrating with technologies such as Home Assistant, Homey, SmartThings, Matter, Thread and Zigbee whenever they add value.
This means your smart home is built for today — and ready for tomorrow.
