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
25-30%
- 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.
