This keypad allows you to activate "scenes" (activity-based lighting setups) and "groups" (lighting areas or zones) in your home automation setup. Set the mood for movie night by dimming the family room lights with one scene, or welcome guests with another scene that lights up all your hallways. The keypad is battery powered, so you don't have to connect it to your home's AC wiring, just place it on the wall. Requires 2 CR2032 batteries, included. Note: Keypad requires a primary controller, such as a Z-Wave remote, Z-Wave computer or Z-Wave IP bridge.
