γSmart SchedulingγStore up to three independent temperature plans, each supporting 7-day weekly scheduling with up to 12 time periods per day. Easily switch between different plans, such as workday, weekend, or holiday modes, to achieve precise and personalized temperature control.
γSmarter HeatingγWorks with a remote temperature sensor for more accurate room temperature measurement. Connects with door/window sensors to reduce or stop heating when windows are open, helping prevent unnecessary energy waste.
γComprehensive ProtectionγFeatures automatic anti-calcification maintenance, frost protection, low battery alerts, and child lock to prevent scaling, freezing damage, unexpected power loss, and accidental operation.
Less Waste,
More Comfort
Zigbee Thermostatic Radiator Valve β TRV Gen2


Compact Design, Great Flexibility
Compared with the previousβgeneration model (TRVZB), its volume is reduced by 38%. It easily fits confined spaces for more flexible, clutterβfree installation.

Crystal-Clear Display from 4-Way Angle


Multiple Weekly Heating Plans for Different Lifestyles
Supports 3 independent heating plans and up to 12 temperature periods, automatically adjusting temperatures to match different household routines while balancing comfort and energy efficiency.
Worried about high energy use?
TRV Gen2 saves energy & costs
Maintain Comfort with External Sensor
Is there a temperature difference between the room and the area around the radiator? Use SONOFF Zigbee Temp & Humidity Sensor as an external probe for true room-temperature control and precise heating.
Dual Open-Window Detection for Smarter Energy Saving
Supports linkage with SONOFF door/window sensor and automatic windowβopening detection. When a window is opened, heating will be automatically stopped to avoid energy waste from continuous heating.

Historical Data Query
You can view three types of data: target temperature, current temperature and Heating activity. Historical records can be traced back up to six months.

*Percentage of device heating duration per hour. Example: 30 minutes of heating within one hour equals a heating activity of 50%.
