Expand your Network

Connect with other Z-Wave devices for personalized scenes and events, like triggering the welcome lights as soon as you walk through the door.

Easy to Spot

Enhanced manual control with an in-built LED indicator that helps you locate the switch in the dark. Automatically restores on or off state after power failure.

Wide Compatibility
