Question about Philips Hue Wandschalter Modul

The module acts as a control device, not as a direct power switch. It sends commands to the bridge, which then switches devices. It is therefore not physically connected directly to lamps/sockets. The wall switch module works with Hue lights and also with the Hue Smart Plug as long as both are integrated via the Hue Bridge and have been linked accordingly in the app.
