This kit uses a wireless switch to easily add on-wall control of an outlet, then simply flip the switch to control a plugged-in lamp or small appliance. To start, replace an existing outlet with the kit's radiant® 15A Outlet (wired). Then use the included battery-powered radiant® Wireless Switch to add on-wall control wherever it is desired. The Wireless Switch mounts to any wall or surface - without cutting, wiring or tools - using the provided adhesive. The devices come pre-paired, letting you add switch control in seconds. Want app control? These devices are equipped for enhanced functionality. Simply add a Smart Gateway with Netatmo and use the Legrand Home + Away app to control your lights from anywhere (and much more). For more information visit www.legrand.us/addappcontrol.
