The Kasa smart Wi-Fi dimmer switch with motion activation combines dimming control, smartphone and voice operation and a built-in motion sensor in a single wall switch. When someone enters the room, the lights can switch on automatically at the preferred brightness, and they turn off again after the room has been empty for a set time. This is convenient in hallways, bathrooms, laundry rooms, garages and closets, where hands are often full, and it helps reduce wasted energy from lights left on. Users can still adjust brightness and create schedules through the app, and the switch connects directly to Wi-Fi without a hub.
