Leviton 300W Decora Smart Wi-Fi Dimmer
Add convenient smart control to your single-color or static-white LED lighting projects with the Leviton® Decora Smart Wi-Fi Dimmer Switch. At the wall, a familiar Decora paddle provides intuitive on/off control, while a dedicated dimming bar and real-time LED level indicators make brightness adjustments simple and precise.
Using the free My Leviton™ app and a Wi-Fi connection—no hub required—you can control lights from anywhere, create schedules based on specific times or sunrise and sunset, group devices together, and activate custom lighting scenes with a tap.
The dimmer is designed to adapt to the way each project is used. Easily adjust brightness settings, fade rates, and other preferences through the app, or take advantage of features like automatic shutoff timers and Home/Away mode for added convenience and security. Even if the internet connection is temporarily lost, your programmed schedules will continue running.
Compatible with dimmable LED strip lights and many common residential lighting loads, it combines reliable performance with intuitive control. Whether you're upgrading a single room or managing multiple lighting zones across a project, it offers a simple way to bring smart dimming, scheduling, and automation together in a single device.
