Transform any home into a smart home with the GE Z-Wave Smart Lighting Control On/Off Switch. The on/off switch replaces your current light switch, uses your existing wiring, and provides Z-Wave wireless and in-wall control of overhead lighting. The switch enables wireless control of on/off functions of direct wire incandescent, LED, xenon, halogen and fluorescent lighting. Providing ultimate flexibility, the GE Z-Wave Smart Lighting Control On/Off Switch allows you to operate the switch by itself or easily integrate the switch with two-way, three-way or four-way wiring configurations by adding the GE Auxiliary switch for Z-Wave. Two-way, Three-way, and Four-way wiring configuration turns the light or appliance on/off from one, two, or three locations. The GE Auxiliary Switch for Z-Wave is required for Three-way or Four-way installations. The lighting control includes a blue LED indicator light to easily locate the switch in a dark room.
