The Legrand WNREZK50WH from the Radiant collection is a 3-way dimmer switch with a wireless dimmer to easily add control of a light or fixture from a second location, even in rooms or locations currently without 3-way wiring. Simply replace the existing switch or dimmer with the kit’s Radiant Tru-Universal Dimmer (wired), then use the included battery-powered Radiant wireless dimmer switch to add another point of control wherever it is desired. Mount the wireless dimmer to any wall or surface – without cutting, wiring or tools – using the provided adhesive. The dimmer switches come pre-paired to enable multi-location control in seconds. Simply add a Smart Gateway with Netatmo and use the Legrand Home + Away app to control your lights from anywhere (and much more).
