Integration
Does KNX work with Loxone?
Absolutely — and it's one of the most popular setups we deliver. KNX devices (switches, sensors, actuators) connect to the Loxone Miniserver, which becomes the central automation brain. The result is the reliability and openness of KNX hardware paired with the ease of use of the Loxone app.
KNX switches and sensors connected to Loxone — the best of both worlds in one installation
Over 500 KNX manufacturers to choose from — no vendor lock-in, maximum flexibility
End users can adjust automations themselves via the Loxone app, even for KNX-connected components
Ideal process
