ThirdReality Matter Smart Switch (MT1)

Quick verdict

This is the ultimate renter-friendly smart switch. It snaps over your existing toggle or rocker switch and physically flips it, so the light still works as a normal switch. Matter-over-Thread support means it plays nicely with Apple Home, Google Home, SmartThings, and Home Assistant (it does not support Amazon Alexa). No electrician needed - but you do need a Thread border router and a Matter controller already on your network to pair it.

Standout: Battery-powered Matter-over-Thread switch that physically flips your existing dumb switch - zero wiring required.
