8. Troubleshooting

If you encounter issues with your Huacaoe Smart Temperature and Humidity Sensor, refer to the following troubleshooting steps:

• Device Not Connecting to Wi-Fi:
  • Ensure your Wi-Fi network is 2.4GHz. The device does not support 5GHz Wi-Fi.
  • Check that the Wi-Fi signal strength is adequate where the device is installed.
  • Restart your Wi-Fi router and the smart switch.
  • Try re-pairing the device by holding the reset button until the indicator flashes quickly.
• Inaccurate Temperature/Humidity Readings:
  • Ensure the sensor probe is clean and not obstructed.
  • Verify the sensor is placed in an area representative of the environment you wish to monitor, away from direct heat sources or drafts.
  • Use the calibration feature in the app settings if you have a reference thermometer/hygrometer.
• App Displaying Incorrect Units (e.g., Celsius instead of Fahrenheit):
  • Check the unit settings within the Tuya Smart/Smart Life app. Ensure Fahrenheit is selected if desired.
  • If the issue persists, especially with voice assistants or automation rules, it may indicate a software limitation from the manufacturer. Ensure the device firmware and app are up to date. Contact customer support if the problem continues after verifying all settings.
• Connected Device Not Responding:
  • Check the wiring connections to the dry contact terminals (NO, COM, NC).
  • Verify that the connected device itself is functioning correctly.
  • Ensure the smart switch is receiving power and is connected to Wi-Fi.
