4-channel relay unit for switching non-dimmable loads — ceiling fans, exhaust fans, sockets, HVAC equipment — from the Casambi network. Each channel is independently controllable from the app or any Casambi switch. Includes these loads in scenes and schedules exactly as you would with lighting circuits.
Key Benefits
Four separately switchable relay outputs in a single unit. Each channel maps to its own Casambi device in the app — control fans, sockets, and loads independently or group them into scenes.
Handles loads that cannot be dimmed — fans, exhaust systems, plug sockets, projector screens — bringing them under Casambi wireless control alongside all dimmable lighting on the same network.
Include relay channels in any Casambi scene or time schedule. Fans turn off when occupancy sensors detect an empty room, or switch on automatically at a set time — no additional wiring or control hardware needed.
