Heat the rooms you use, when you use them. The SONOFF TRV-ZBT Gen2 is a Zigbee smart thermostatic radiator valve that replaces your manual valve head and controls each radiator from your phone. It is 38% smaller than the previous generation, runs quietly, and shows temperature and status on a crisp IPS color display that rotates in four directions. 🔥🏠✨
Store up to three heating plans, each with a 7-day schedule and up to 12 time periods per day, so workdays, weekends, and holidays each get their own routine. Pair it with a SONOFF temperature sensor for true room-temperature control, and with a door or window sensor so heating stops automatically when a window is opened. This helps avoid wasted heat and can help lower your energy use.
⚠️ Important Note
A Zigbee hub or gateway is required, and it is sold separately. The valve fits radiator valves with an M30 x 1.5mm thread, and the package includes adapters for many heating brands. Please check your valve thread type before ordering. It is powered by 2 AA batteries, so please check the package contents for included batteries. ✅📡
