No Neutral Wire? No Problem.

Published June 2022

While many homes built after the 1980’s included a neutral wire, it was not required by the electrical code. In 2011, the National Electrical Code began to transition new home construction to require a neutral wire in every switch wallbox. While newer homes include neutral connections, older homes may or may not have a neutral connection available. A challenge has been that most smart dimmers and switches require a neutral wire to function to complete the circuit allowing power 24/7 for the communication radio in the device.

Homeowners with older homes have been limited in choice to smart bulbs or more costly options for smart in-wall devices that do not require a neutral or have had to hire an electrician to run neutral wires.

The Decora Smart No-Neutral products work with the My Leviton platform, which offers a full portfolio of connected lighting and load controls with a solution for every room and home. The No-Neutral solution includes a compact Wi-Fi Bridge and corresponding Decora Smart No-Neutral Switch and Dimmer. The Wi-Fi Bridge’s small convenient size plugs in an outlet and does not need an ethernet cable. The bridge uses a local RF connection to communicate to No-Neutral Dimmers and Switches and enable smart features such as My Leviton app control for scenes, schedule setup, and pairing with Wire-Free Anywhere Companions, for 3-way/multi-location control. The Bridge provides up to 2,500 sq. ft. of coverage when placed in a central location within 50 ft. of Decora Smart No-Neutral devices. One smart Bridge can support up to 25 dimmers or switches. The Bridge also enables choice of voice with Amazon Alexa, Hey Google™, or Apple HomeKit/Siri.
