This wireless WiZ motion sensor for indoor use utilizes motion detection to turn lights on and off. Position it at the entrance or in a hallway and select your desired light modes as you pass by. When you leave the room, the light can be turned off or the brightness can be reduced. The motion sensor has a range of up to 3 meters and controls all lights in a room. In the WiZ app, set different light modes to be used throughout the day, such as warm white in the evening and night light at night.
