The Decora Smart® Anywhere Dimmer Companion pairs wirelessly with your Decora Smart Wi-Fi® 2nd Generation D26HD, D2MSD, D23LP, D24SF and DN6HD/MLWSB to provide additional control 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 Dimmer 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 the Decora Smart Wi-Fi 2nd Gen Mini Plug-In Dimmer to add a wall mounted dimmer for your connected plug-in lamps
