Bi-directional KNX to Casambi bridge for seamless BMS integration. Map KNX group addresses to Casambi scenes, groups, and individual devices — so a KNX building management system can trigger Casambi lighting scenes directly, and Casambi status is fed back to KNX in real time.
Key Benefits
Commands flow in both directions. KNX can trigger Casambi scenes, and Casambi status — dimmer levels, on/off state — is reported back to KNX in real time for building management dashboards.
Map any KNX group address to a Casambi scene, group, or device. The bridge translates KNX telegram types (switching, dimming, scenes) to native Casambi commands — no additional middleware needed.
Enables Casambi to sit within a full KNX building management system alongside HVAC, access control, and AV. One BMS interface controls all systems — standard for large commercial and hospitality projects.
