Description
Visit thermostatic valve Sonoff TRVZB is an intelligent device designed to control your radiators via Zigbee 3.0transforming a conventional radiator into an autonomous home automation device. It integrates perfectly into a system controlled by a Raspberry PiThis is the ideal solution for managing, monitoring and automating your heating system, room by room.
Fine-tuned, connected thermal control
- Allows you to set the room temperature over a range of 4 °C to 35 °C
- Precise control via home automation app or programmable scenarios
- Instantaneous, fluid control, directly supervised locally
Automation and intelligent comfort
- Window opening detection the valve automatically switches off heating when ventilation is detected, to avoid energy wastage
- Frost protection prevents pipes from freezing by maintaining an appropriate minimum temperature
- Child lock : secures the valve against unintentional adjustment
Home automation integration with Raspberry Pi
Thanks to its Zigbee protocol, this valve can be linked to a local gateway (Zigbee2MQTT or ZHA). It then becomes a central component for :
- Time programming (heating at fixed time, absence, night, weekend, etc.)
- Intelligent automation via Home Assistant or Node-RED ("vacation mode" scenarios, weather-compensated modulation, etc.)
- Display status and settings in your home automation dashboard
- Voice or remote control with compatible connected assistants
