Wireless Single Lighting Control, No Hub Needed

Control plug-in lights locally or with a smartphone via Wi-Fi with the Leviton Decora Smart Wi-Fi Plug-In Dimmer. The dimmer can command and schedule plug-in devices to turn On/Off and Dim/Brighten at scheduled times or according to programmed events or scenes. Simply plug a light into the module, and plug the module into a power outlet. Unlike most wireless devices, the Smart Wi-Fi Plug-In Dimmer requires no automation hub or gateway to operate; the module can be controlled directly from a smartphone or tablet app over Wi-Fi.

The button on the front of the Dimmer is used for manual On/Off and Dim/Brighten control. In case of power malfunctions, the Dimmer remembers the status of plugged-in devices.
