The Leviton Decora Smart Wi-Fi 2nd Generation Scene Controller Switch makes it easier than ever to control lights and other connected devices with the touch of a button. Simply replace your existing light switch to get both a smart switch and gain 3 extra scene buttons. The Scene Controller Switch can be paired with the My Leviton app and Decora Smart Wi-Fi devices to create a wireless home lighting control system. The bottom button controls the built-in switch for wired loads/lights and works with Hey Google, Alexa or HomeKit/Apple Siri for voice control. Use the My Leviton app to assign custom room scenes or activities, such as Movie Time or All Off to the buttons.
