The Decora Smart™ Wi-Fi 4-button controller provides sophisticated in-wall control of multiple Decora Smart™ Wi-Fi devices, room lighting scenes and whole house lighting activities. Pairs with Decora Smart™ Wi-Fi lighting controls and the My Leviton® app to offer an "always there, always on" control center for smart lighting. Adjust devices, activate scenes in a room or push one button to turn off every light in the home. The DW4BC requires hot, neutral and ground wires and does not directly connect to a load.
