The TALK MODULE EnOcean G1 is a retrofittable radio module. In conjunction with the Waldmann luminaire control system, it reacts to presence and absence, allows luminaires to communicate wirelessly with each other in groups (swarm control) and thus always creates a pleasant lighting scenario without islands of light in the architectural luminaires. At the same time, the luminaire's presence information can be passed on via the building management system. This opens up a large energy-saving potential in room automation. Settings can be made via the coding switches located on the module or via the EnOcean Desktop application.
