Smart lighting is one of the easiest ways to make your home more efficient, convenient, and modern. Whether you want voice control via Alexa or Google Assistant, set schedules, or automate your entire home, smart light switches can turn even ordinary bulbs into smart ones – without changing every fixture.
In this guide, we’ll cover everything you need to know to choose the best smart light switch for your home, compare 10 of the best models on the market, and help you find the perfect balance of price, features, and ease of installation.

- Remote access: Turn lights on/off while away.
- Scheduling & automation: Create sunrise/sunset routines.
