The Wire-Free Smart Motion Sensor adds programmable motion to Cync Smart Bulbs, Smart Switches and Smart Plugs. The sensor automatically turns lights and devices on when motion is detected in the room and turns them off when the room is unoccupied. The smart Bluetooth sensor connects wirelessly to Cync Smart Bulbs, Smart Plugs and Smart Switches to provide whole room motion control. The motion settings are adjustable so lights can come on slowly at nighttime or be set to deactivate during certain times. Set lights to turn on based on natural light and motion in the room. Pair with a Cync Smart Plug and automatically turn off devices like curling irons after you left the room. With a replaceable battery rated to last over two years and multiple mounting and positioning options, it's easy to get expansive motion coverage anywhere in your home
