# Smart switch

A smart switch replaces a regular wall switch and adds wireless control, so lights respond to an app or a voice assistant.

Leviton says a smart switch lets you turn lights on and off with its app or a favorite voice assistant. Leviton also notes that some of its smart devices work in homes that may not have neutral wiring. Check this before you buy, because some brands need a [neutral](https://danielelectric.multisites.ai/glossary/neutral) wire in the box.

Installing one means opening a live switch box, so use a licensed electrician. A smart [dimmer switch](https://danielelectric.multisites.ai/glossary/dimmer-switch) adds brightness control. A [three-way switch](https://danielelectric.multisites.ai/glossary/three-way-switch) circuit needs a compatible companion. See [lighting installation](https://danielelectric.multisites.ai/lighting-installation).
