SONOFF TRVZB Zigbee Smart Thermostatic Head, 2-Pack

Product detailed description

The SONOFF TRVZB is a smart thermostatic head with a ZigBee interface that allows you to conveniently regulate the temperature in individual rooms and better manage energy consumption. The device supports both automatic and manual modes, heating schedules, open-window detection, and a freeze protection feature. Thanks to integration with popular smart home systems, you can control your heating from a smartphone, tablet, computer, or central control panel, no matter where you are.

Remote Control and Schedules TRVZB allows for convenient control of your heating system via an app available on smartphones, tablets, and computers. In the interface, you can check the current temperature, heating status, and battery level, as well as set the desired operating temperature. The thermostat also allows you to create detailed heating schedules for each day of the week, automatically lowering the temperature when you’re away and raising it before you return home, which increases comfort and helps reduce energy consumption.

Energy Savings and Individual Control The open-window detection feature automatically turns off the heating as soon as it detects a sudden drop in temperature, thereby reducing energy loss during ventilation. The thermostat also allows for independent temperature control in each room, so you can set different settings for the living room, bedroom, children’s room, or home office. This makes it easier to enhance the comfort of household members and prevent unused rooms from overheating.

Smart scenes and group control
The TRVZB thermostat can work with temperature and humidity sensors and use their readings as a reference temperature for heating control. It also supports smart automation scenes with other smart home devices, such as modules for controlling the heating source. In addition, it allows you to group multiple thermostatic valves so you can control heating in multiple rooms simultaneously with a single command—for example, by switching all radiators to frost protection mode.

Wide Compatibility and Home Assistant TRVZB works with SONOFF ZBBridge-P, ZBBridge-U, NSPanel Pro, and iHost gateways, as well as the Zigbee2MQTT platform. All key features, such as schedules, temperature calibration, open-window detection, parental controls, operation history, and OTA updates, are available on compatible systems. The thermostat can also be integrated into Home Assistant via Zigbee2MQTT, providing access to temperature control, operating modes, parental controls, temperature calibration, anti-freeze protection, battery status monitoring, and device operation history. Comfort, Safety, and Operation History
The TRVZB model offers a parental lock feature that prevents accidental changes to the settings, automatic calibration to ensure proper valve operation, and a freeze protection feature that automatically activates the heating at low temperatures, thereby protecting the heating system from damage. The device also records historical data on temperature and preset values and displays them in hourly, daily, and monthly summaries, which facilitates the analysis of the heating system’s operation and the optimization of heating schedules.
