Smarter, more convenient heating control for your home
The radiator thermostat that can be used with most water heaters such as space heaters, towel warmers or even underfloor heating. It takes readings from external Aqara sensors and adjusts the heat output accordingly.

Readings from external temperature sensor (including HomeKit):Control the temperature of the entire room, not just around the radiator. Compared to other thermostats, the Aqara Radiator Thermostat can receive temperature readings directly from the connected Aqara Temperature and Humidity Sensor or TVOC Air Quality Monitor (sold separately), even in HomeKit!

Advanced detection of door and window openings:To avoid wasting energy, the TRV switches off the heating when an open door or window is detected. This can be done either via the built-in temperature sensor, which detects a sudden drop in temperature, or by connecting to an Aqara door and window sensor via automations, which are more reliable.

Weather automation and freeze protection:If there is a risk of pipes freezing, the heating is switched on automatically. In addition, thanks to the powerful Aqara Home automation, if the outside temperature drops significantly, the room can be preheated to compensate for the temperature difference.

Configurable smart schedules:The schedules can be set for the desired time periods, such as night, and the transition between them is smooth but as fast as possible.

Device grouping support:If there are multiple radiators in a room, they are all synchronised in the most efficient way based on the actual room temperature.

Colourful backlit display:Compared to similar products, the LCD screen of the Aqara radiator thermostat has a backlight, a wider viewing angle, extra high contrast and crisp and colourful icons.

1Year of battery life:Thanks to the Zigbee protocol and energy-efficient hardware, the battery of the Aqara radiator thermostat can last up to a year.
