For Z-Wave protocol, the range is about 100-feet (30-meters) but it depends upon the materials in the way of the devices. Certain obstructions will decrease the Z-Wave range:

  • Each wall or obstacle (such as refrigerator, big screen TV, etc.) between the

controller and a Z-Wave device will reduce the maximum range by approximately


  • Brick, ceramic tile, granite, concrete walls, metal walls, mirrors, and smoked glass

block Z-Wave signals more than walls made of wooden studs, plasterboard (drywall),

clear glass, or plastic

  • Wall mounted Z-Wave devices installed in metal junction boxes will suffer a

significant loss of range (approximately 20%) since the metal box blocks a large part

of the Z-Wave signal

  • All Z-Wave devices that plug directly into an AC wall power outlet, such as dimmers

and smart switches, act as "repeaters." You can also buy a repeater as a standalone

accessory device. If a Z-Wave device does not appear to be communicating with the

controller, try plugging in a repeater approximately halfway between the device and

the controller.
