Simply retrofit and switch smartly
Do you also have a staircase where only one ceiling light is placed? Of course you've installed a pushbutton on each of the two floors so that you don't have to run to one of them each time to switch on the light With the Homematic IP switch actuator for DIN-rail mounting, you can also make this light smart at a later date! The actuator is installed in the control cabinet and connected to the light in the room and to a pushbutton. Control the light fully automatically or simply via the existing pushbuttons.
