The Decora Smart® Anywhere Switch Companion pairs wirelessly with any Decora Smart Wi-Fi® 2nd Generation device, including D26HD, D215S, D2MSD, D2SCS, D24SF, D23LP, D215P, D215R, or DN6HD/DN15S via MLWSB, to provide additional ON/OFF lighting control locations wherever you need it most such as at the base of a staircase, the end of a hallway or open areas with multiple entrances like a large kitchen or family room. Mount it directly on the wall surface or at an existing single or multi-gang wallbox – no wiring is required. The Decora Smart Anywhere Switch Companion is the perfect solution for locations where wiring or a wallbox with a traveler wire may not be present. For added convenience, you can even control Decora Smart Wi-Fi 2nd Gen Mini Plug-Ins to add a wall mounted switch to control your connected plug-in lamps, electronics, or small appliances.
