  • Try resetting the thermostat to factory settings (refer to PDF manual) and re-pairing with the app.
  • Ensure the Tuya Smart/Smart Life app is updated to the latest version.
  • If using Zigbee2mqtt, verify compatibility and correct configuration, as some users have reported issues with full functionality beyond link quality.
• Incorrect Temperature Readings:
  • Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources that could affect its internal sensor.
  • Calibrate the temperature sensor through the advanced settings in the app if necessary.

10. User Tips

• Choose the Right Model: The WT100 series comes in different versions (WiFi/16A for Electric Heating, WiFi/3A for Water Heating, and WiFi/3A for Gas Boiler). Ensure you have the correct model for your specific heating system to avoid compatibility issues during installation and operation.
• Keep Manual Handy: If you misplace the physical manual, remember that detailed instructions for Wi-Fi setup and advanced features are often available in the app or as a downloadable PDF.
• Backlight Aesthetics: Some users have noted that the backlight may not be perfectly isolated, leading to light bleed around the edges. While this is generally an aesthetic observation and does not affect functionality, it's something to be aware of.
• Zigbee Compatibility: If you plan to integrate with Zigbee2mqtt, be aware that full functionality might require specific configurations or may be limited to basic controls. Always check for updated device handlers or community support for advanced integration.
