Product Information

Sonoff Zigbee Thermostatic Radiator Valve | TRVZB

Sonoff Zigbee Thermostatic Radiator Valve | TRVZB

The Sonoff Zigbee Thermostatic Radiator Valve (TRVZB) allows precise temperature management through the eWeLink app and Zigbee 3.0 connectivity. Powered by 3 × 1.5V AA batteries. Compatible with Lebanese standard radiator valves. Ideal for multi-room temperature control, the TRVZB helps reducing heating costs. To work, it needs a Sonoff Zigbee Hub ( you can use ZBBridge-P or ZBBridge-U or NSPanel Pro or iHost) and once connected, it’s easy to integrate into your smart home setup.

Benefits:

  • Smart remote control: Adjust your radiator temperature from anywhere via the eWeLink app or voice assistants (Alexa, Google Assistant).

  • Maintain comfort with external sensor: Pair with Sonoff Zigbee temperature sensor for more accurate room readings — the radiator turns on automatically when a temperature drop is detected.

  • Adjust valve percentage: Manually fine-tune the valve opening or closing level to match your exact heating needs.

  • Temperature calibration: Calibrate temperature readings for more precise comfort and consistent performance.

  • Open window detection: Automatically pauses heating when a window is open, helping prevent unnecessary energy waste.

  • Group control: Manage all radiators in your home with one click — ideal when leaving the house or switching modes.

  • Scheduling and automation: Set heating schedules according to your routine for better comfort and energy savings.

  • Zigbee 3.0 compatibility: Works with Sonoff Zigbee hubs and most Zigbee 3.0-compliant gateways.

  • Child lock & frost protection: Protects against accidental setting changes and frozen pipes in cold weather.

  • Comprehensive data tracking: Stores up to 6 months of usage data for better heating insights and optimization.

  • Easy installation: Fits standard M30 × 1.5 mm radiator valves with adapters for wide heating system compatibility.
