Updated November 2026

It connects over Bluetooth to a Shelly BLU Gateway rather than a Zigbee hub, and pairs with an external Shelly BLU H&T sensor for a more accurate room reading than either valve's own built-in sensor. The Aqara Radiator Thermostat E1 answers back with the deeper integrations, reaching Apple HomeKit, IFTTT and Matter through an Aqara hub alongside Google Home, Alexa and Home Assistant, and it adds geofencing to pre-heat as you approach plus frost protection the Shelly does not have at all. Choose the Shelly BLU TRV for the longer battery life, the better rating and quiet, accurate regulation; choose the Aqara Radiator Thermostat E1 for HomeKit, Matter, geofencing and frost protection.

What the differences mean

Radio and hub

The Aqara Radiator Thermostat E1 connects over Zigbee to an Aqara hub. The Shelly BLU TRV connects over Bluetooth to a Shelly BLU Gateway, which has to stay powered for remote and voice control to work.

Battery life

The Shelly BLU TRV is rated for roughly double the battery life of the Aqara Radiator Thermostat E1 on the same two AA cells, meaning fewer battery changes per heating season.

Warranty

The Shelly BLU TRV carries a longer warranty than the Aqara Radiator Thermostat E1.

Geofencing and frost protection

The Aqara Radiator Thermostat E1 pre-heats as you approach home with geofencing and guards against frozen pipes with frost protection. The Shelly BLU TRV has neither feature.

Platform reach

The Aqara Radiator Thermostat E1 reaches Apple HomeKit, IFTTT and Matter through an Aqara hub, on top of Google Home, Alexa and Home Assistant. The Shelly BLU TRV covers Google Home, Alexa, Samsung SmartThings and Home Assistant, but not Apple HomeKit, IFTTT or Matter.

What owners say

Owners of both valves report accurate, unobtrusive heating control once installed, with one shared caveat: each valve's own built-in temperature reading can be thrown off by heat coming straight off the radiator, and owners of both add an external sensor elsewhere in the room for a truer number. Aqara Radiator Thermostat E1 owners value fast pairing with Home Assistant, Zigbee2MQTT and Apple HomeKit plus genuinely useful geofencing and frost protection, but a recurring group reports mounting parts turning brittle or the motor losing its Zigbee pairing after a year or two of daily use. Shelly BLU TRV owners praise how quiet and precise the valve's regulation is and find installation quick with the included adapters, but say the Shelly BLU Gateway has to stay powered and well placed or Alexa responsiveness and Bluetooth range both suffer.
