Full details

The SONOFF TRV-ZBT is designed for homeowners seeking precise room-by-room heating control and improved energy efficiency through smart automation. Its primary benefit is the ability to create complex heating schedules and integrate with external sensors, though it does require a compatible Zigbee 3.0 gateway for full smart functionality. This valve combines a high-resolution IPS display with intelligent features like window detection and frost protection to simplify indoor climate management.

FAQs

Do I need a hub for this device?

Yes, a Zigbee 3.0 gateway is required for smart control and integration.

Can I use this with Home Assistant?

Yes, the TRV-ZBT is compatible with Zigbee 3.0 ecosystems, including Home Assistant.

What is the anti-calcification mode?

This is a maintenance cycle that moves the valve periodically to prevent it from seizing up due to mineral deposits.

How many schedules can I set?

The device supports up to 3 distinct schedules with 12 time periods per day.

Does it detect open windows?

Yes, it features dual window detection that pauses heating when it senses a sudden drop in temperature.

What happens if the battery runs out?

The device will stop active regulation; it is recommended to monitor battery status in your app and replace them before they are fully depleted.

Troubleshooting

Device is not appearing in the Zigbee gateway

Ensure the device is in pairing mode and check that your gateway supports the Zigbee 3.0 protocol.

Temperature readings seem inaccurate

Consider pairing the TRV with an external temperature sensor to avoid heat interference from the radiator itself.

Screen is difficult to read

Use the settings menu to adjust the screen orientation; the IPS display supports 4-way rotation.

Pros and Cons

Pros

  • Highly granular scheduling options
  • Clear, rotatable high-resolution IPS screen
  • Includes essential energy-saving features like window detection
  • Compatible with open platforms like Home Assistant
  • Automated maintenance cycles prevent valve sticking

Cons

  • Requires a separate Zigbee 3.0 hub to function

Setup, Compatibility & Care

To install the TRV-ZBT, ensure your radiator system uses a compatible valve interface. The device is designed for easy mounting but may require specific thread adapters depending on your existing radiator type. Once physically installed, you must pair the device with your Zigbee 3.0 gateway through your preferred smart home app. For care, ensure the valve is kept free of dust. While the device handles anti-calcification automatically, it is recommended to check the battery levels periodically via your smart home dashboard to ensure continuous operation, especially before the start of the winter season.
