Lighting control from a single sensor to a whole building: DALI-2 sensors, couplers, relays and push-button interfaces, stand-alone DALI controllers, Casambi Bluetooth modules, Inventronics HubSense wireless control, and the e:cue SYMPHOLIGHT platform for architectural and media lighting. Typical installations are offices, classrooms, conference rooms, stairways and storage areas, where presence and daylight sensing switch and dim the lights without anyone touching a switch.
