  • Ensure your Wi-Fi router is operational and broadcasting a 2.4 GHz network.
  • Check the Wi-Fi indicator on the receiver unit.
  • Restart your router and the receiver unit.
  • Ensure correct Wi-Fi password entry in the Tuya Smart app.
• Heating System Not Responding:
  • Verify the wired connection between the receiver unit and the heating boiler.
  • Check the thermostat's operating mode (heating/cooling) and set temperature.
  • Ensure the heating system itself is functional.
• Inaccurate Temperature Readings:
  • Ensure the central unit is not placed near heat sources, direct sunlight, or drafts.
  • The thermostat has a sensor calibration setting; refer to the full manual for adjustment.
