Aqara Smart Thermostat W200 with Apple Adaptive Temperature &

Quick verdict

Based on published specs and editorial comparison, the Aqara W200 is the outlier here as a Matter-controller smart thermostat rather than a camera, aimed at automation-minded homes prioritizing ecosystem fit over surveillance. Its listed support for Apple Home, Siri, Google Assistant, and Alexa plus a built-in radar sensor and 4-inch touchscreen positions it for Matter-first households that want presence-aware climate control as part of a broader smart-home routine. Choose it for cross-platform integration, not for resolution or storage considerations.
