Leviton’s Decora Smart Wi-Fi Bridge is an easy-to-install
plug-in that enables smart features and connectivity to
services such as My Leviton, Apple HomeKit, Amazon Alexa,
and Google Assistant for Decora Smart No-Neutral devices.
Its small form factor lets you plug it in out of the way,
without taking up space on a shelf or desk.
Pairing a Decora Smart No-Neutral Dimmer or Switch with
a Wi-Fi Bridge makes it easier than ever to install smart
lighting control in homes without Neutral wiring in the
electrical wall box.
