Buying Guide
What should guide your choice when shopping for a 3-way smart light switch?
- Compatibility with your ecosystem: Do you use Alexa, Google Assistant, Apple HomeKit, or Samsung SmartThings? If you want Matter support, prioritize devices designed for cross-brand interoperability.
- Wiring requirements: Most 3-way switches require a neutral wire. Verify your wall box wiring before purchasing. If you’re unsure, consult a licensed electrician.
