The Aqara Smart Thermostat W200 has a 4-inch color touchscreen, built-in mmWave radar presence sensing and a Zigbee, Thread and Matter hub. It works locally with Apple Home, Google Home, Alexa and SmartThings, and sells for about $130 to $150.
What you need before you buy
- A compatible HVAC system; Aqara says about 85% of homes qualify.
- Wi-Fi and the Aqara app, or your Matter platform of choice.
- An Apple Home setup if you want Adaptive Temperature.
How it saves energy
Radar presence sensing lowers heating or cooling when rooms are empty, and in Apple Home it can shift usage toward cleaner grid hours.
