SONOFF TRVGen2 Zigbee Smart Thermostatic Valve

SONOFF TRV Gen2 Zigbee Thermostatic Head
With the SONOFF TRV Gen2 Zigbee smart thermostatic head, you can control the temperature in your home more conveniently. The device allows for precise heating control, the creation of custom timetables and integration into a smart home system via the Zigbee 3.0 protocol. Thanks to its compact design, quiet operation and automation features, you can tailor the operation of your radiators to your day-to-day needs.

Compact design and user-friendly controls
The SONOFF TRV Gen2 is 38% smaller than the previous generation, making it easier to install in confined spaces or where pipework is more complex. The valve’s smooth adjustment mechanism operates quietly, ensuring comfort even at night. The device is fitted with a colour IPS display that shows the current temperature, settings and operating status, and thanks to the ability to rotate the display in four directions, you can adjust its position to suit the installation.

Smart heating schedules
The thermostat allows you to save up to three independent temperature schedules, enabling you to set different configurations for weekdays, weekends or periods when you are away from home. Each schedule supports a 7-day weekly cycle and up to 12 time slots per day. This solution allows you to precisely tailor the temperature to your daily routine and conveniently manage your heating without frequent manual adjustments.

Automatic temperature control and more energy-efficient heating
The SONOFF TRV Gen2 can work in conjunction with a remote temperature sensor to monitor indoor conditions more accurately. When combined with door and window sensors, you can create automations that reduce or switch off the heating as soon as an open window is detected. Zigbee integration also allows you to connect the thermostat to other smart home devices and create scenarios tailored to current conditions.

Safe operation and easy installation
The device offers protective features such as automatic valve maintenance to prevent limescale build-up, frost protection, low-battery alerts and parental controls. The thermostatic head uses a standard M30 × 1.5 mm connection and, thanks to the included CAL, RAVL, RAV, M28, GIA and RA adaptors, can be adapted to various types of valves. It is powered by two 1.5 V AA LR6 batteries, enabling wireless installation and convenient use.

Compact design
The head is made from durable PC plastic, and its compact dimensions of 50 × 50 × 82.9 mm help to maintain the aesthetic appearance of the radiator system. The device weighs 169 g including batteries, making it lightweight and easy to install. The SONOFF TRV Gen2 is designed to operate at temperatures ranging from -10 °C to 50 °C and at relative humidity levels of 5–95 per cent, provided there is no condensation. The valve control mechanism has a service life of 10,000 operating cycles, ensuring reliable performance in everyday use.
