CASAMBI CGW-KNX

The Casambi KNX DALI Hybrid Gateways enable seamless integration between Casambi wireless lighting networks and KNX building automation systems. By combining KNX-DALI and Casambi control into one ready-made solution, they simplify installation and ensure reliable operation.

Casambi luminaires appear in KNX ETS as standard DALI devices, allowing control via switches, sensors, and touch panels, including dimming, tunable white, and RGB functions.

Models:

• CGW-KNX-01-B:
  Controls up to 64 luminaires via a single DALI bus. Ideal for smaller projects.
• CGW-KNX-02-B:
  Controls up to 128 luminaires (2 × 64) with two DALI buses. Designed for larger or multi-zone installations.

The Casambi KNX DALI Hybrid Gateway wireless systems can be configured through the Casambi app, The Casambi app can be downloaded free of charge from Apple App Store and Google Play Store.
