On a valve tucked behind a radiator, halving the number of battery changes is worth more than it sounds, and it connects over Wi-Fi and Bluetooth rather than needing a Zigbee coordinator. The Aqara Radiator Thermostat E1 is the better connected of the two: through an Aqara hub it reaches Apple HomeKit, IFTTT and Matter as well as Google Home, Alexa and Home Assistant, where the Shelly stops short of HomeKit and Matter, and it adds geofencing to pre-heat as you approach plus frost protection to keep pipes safe in an empty house. Choose the Aqara Radiator Thermostat E1 for HomeKit, Matter, geofencing and frost protection, and the Shelly BLU TRV for double the battery life and warranty.
