Product Information
Sonoff Zigbee Thermostatic Radiator Valve (TRVZB)
This smart radiator valve replaces your existing TRV (the knob on your radiator) and lets you control the heating from your phone. Set precise temperatures, create schedules, and save on heating bills — all through a Zigbee (a wireless smart home protocol that connects devices through a hub) hub and the eWeLink app.
Compatible with Lebanese standard radiator valves. Powered by 3 x AA batteries.
Key Features:
- Precise Temperature Control: Set each room to your desired temperature — no more guessing with the manual knob.
- Smart Scheduling: Set different temperatures for different times of day — warm in the morning, lower when you’re at work.
- Multi-Room Control: Install one on each radiator and control every room independently from your phone.
- Child Lock: Prevent kids from changing the temperature.
- Open Window Detection: Automatically reduces heating when it detects a sudden temperature drop (window opened).
- Battery Powered: 3 x AA batteries — lasts a full heating season.
- Home Assistant Compatible: Works with ZHA and Zigbee2MQTT.
💡 Pro Tip: Install one in each room and set a schedule: warm up the bedroom 30 minutes before you wake up, lower the living room when you go to sleep. You’ll stay comfortable and reduce your heating bill.
