The Leviton Decora Smart No-Neutral Dimmer is a retrofit rocker switch designed for existing installations where a neutral wire is not present. The No-Neutral Dimmer provides On/Off and Dim/Brighten controls over connected dimmable lights and small appliances. When paired with the Decora Smart Wi-Fi Bridge (MLWSB, sold separately), the No-Neutral Dimmer can connect with the My Leviton mobile app to enable wireless remote control over wired loads, allowing the controlled devices to be included in smart routines or automated schedules. This product requires a MLWSB Decora Smart Wi-Fi Bridge (sold separately) to enable smart and remote control features such as connection with the My Leviton App, inclusion into automated scenes or schedules, 3-way or multi-way applications with Leviton Anywhere Companion devices, and integration with smart home services including voice assistants.
