Check your existing valve before ordering
The smart head replaces a compatible thermostatic radiator-valve head. Check the valve body, thread and any required adapter; a photo of the old head alone may not identify the connection. Do not remove the plumbed valve body or loosen pipework.

Installation, calibration and pairing
- Check the correct adapter and install fresh batteries according to the manual.
- Follow the manufacturer’s mounting and initial calibration sequence before pairing.
- Add the valve through your compatible Zigbee gateway. App and voice-control functions depend on the gateway.
Open the official SONOFF TRVZB manual with installation and display diagrams (PDF).
A radiator head controls flow through its radiator; it does not by itself replace boiler controls. Ask an installer if you are unsure about your valve type.
Results depend on your home, existing heating or glazing, fitting and use. No fixed energy-bill saving is guaranteed.

CHECK BEFORE BUYING
Check your valve and gateway.
A radiator valve and Zigbee gateway must both be compatible.
- Check the valve connection and any adapter requirement.
- Confirm that your Zigbee gateway and app support the features you want.
- Review the selected pack quantity and what is included.
Do I need a hub?
Yes, a compatible Zigbee gateway is required for connected functions.
Does it replace a boiler thermostat?
A smart radiator valve controls a suitable radiator. It does not replace your main boiler control.
Will it reduce my energy bills?
It may help you use heat more effectively or reduce wasted warmth, depending on the product and your home. Results vary with your heating system, windows, installation and usage. No fixed saving is guaranteed.
