Control is also available remotely via compatible smart home systems.
Remote control and weekly schedules

Remote control and weekly schedules

Set the desired temperature and create detailed heating schedules for each day. In the app you can clearly see the current temperature, heating status, and battery level, and conveniently adjust the heat from anywhere.

Energy savings with open-window detection

Energy savings with open-window detection

The open-window detection feature reacts to a sudden temperature drop and helps automatically reduce heating while airing out the room. Thanks to individual room-by-room control, you can set different values for the bedroom, living room, and office and avoid overheating.

Wide compatibility and smart scenes

TRVZB works with gateways SONOFF ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost and the Zigbee2MQTT platform. It supports smart automations, group control, and key features such as temperature calibration, child lock, frost protection, and OTA updates. It can also be integrated into Home Assistant via Zigbee2MQTT.

Sonoff TRVZB is a smart thermostatic radiator valve with a ZigBee interface that increases home comfort and helps you manage energy consumption more effectively. It supports automatic and manual modes and lets you set a target temperature for different rooms so you do not heat unnecessarily where you are not currently present.

In the app, you can easily check the current temperature, heating status, and battery level, and set detailed time schedules for each day of the week. Thanks to smart scenes, heating can be linked with other smart home elements, and multiple valves can be grouped for shared control.
