Its battery rating is the edge that decides it: 1 year on two AA cells against 10 months. The SwitchBot Smart Radiator Thermostat is the better reviewed, talks over Bluetooth instead of Zigbee, and can build schedules automatically. Both show temperature on a screen, both have frost protection, and both need their own hub for Alexa, Apple Home, Google Home and Matter. Pick the Aqara Radiator Thermostat E1 for the longer cells and an external sensor, and the SwitchBot head if Bluetooth and automatic schedules matter more.

What the differences mean

Battery life

Both radiator valves run on two AA cells. The Aqara Radiator Thermostat E1 is rated for 1 year. The SwitchBot Smart Radiator Thermostat is rated for 10 months. That is the spec the comparison scores to the Aqara head. Neither figure is a decade, so plan on replacing cells, just less often on the Aqara.

Zigbee or Bluetooth

The Aqara Radiator Thermostat E1 needs a Zigbee hub and has no Bluetooth. The SwitchBot Smart Radiator Thermostat uses Bluetooth and has no Zigbee. A house that already has an Aqara or other Zigbee coordinator stays with the Aqara head. A house that already has SwitchBot Bluetooth gear stays with the SwitchBot head. They do not join each other's radio.

Schedules and external sensors

Automatic scheduling is on the SwitchBot Smart Radiator Thermostat and not on the Aqara Radiator Thermostat E1, which is manual scheduling only. An external temperature sensor is supported on the Aqara head. On the SwitchBot head it is sold separately, so the capability is there once you buy the sensor, not in the box. Geofencing is on the Aqara head and is not published for the SwitchBot head.

Hubs for the assistants

Home Assistant is direct on both. Alexa, Apple Home, Google Home and Matter need an Aqara hub on the Aqara Radiator Thermostat E1 and a SwitchBot hub on the SwitchBot Smart Radiator Thermostat. SmartThings is listed on the Aqara head and needs the SwitchBot hub on the other. Warranty is 1 year on both. The SwitchBot head weighs 270 g against 150 g for the Aqara head.

Which one to buy if

What owners say

Owners of both radiator valves say the head screws on in minutes and that the win is heating one room instead of the whole house. They flag different limits. Aqara Radiator Thermostat E1 owners single out fast pairing, an external temperature sensor and geofencing, and a share of them report the motor, the mounting splines or the Zigbee link degrading after a year or two of daily moves. SwitchBot Smart Radiator Thermostat owners single out the adapters in the box, a display that is easy to read, and Home Assistant over Bluetooth, and they warn that the head cannot call for heat from the boiler, that voice assistants need a separate SwitchBot hub, and that some schedules did not stick without a re-sync.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
