6. Troubleshooting

• Device not connecting to app:
  • Ensure your Wi-Fi network is 2.4GHz. The sensor does not support 5GHz Wi-Fi.
  • Verify that your phone's Wi-Fi and Bluetooth are enabled.
  • Check if the device is in pairing mode (blinking indicator light). If not, refer to the app's instructions for resetting the device to pairing mode.
  • Ensure your Wi-Fi signal is strong where the sensor is located.
  • Restart your router and try pairing again.
• Inaccurate readings:
  • Ensure the sensor is not placed near heat sources, direct sunlight, or areas with high airflow (e.g., near vents or open windows) that could affect readings.
  • Use the in-app calibration function to adjust temperature and humidity values if you have a reliable reference instrument.
  • Check battery level; low batteries can sometimes affect sensor performance.
• App notifications not received:
  • Verify that app notifications are enabled in your smartphone's settings.
  • Ensure the sensor is connected to Wi-Fi and reporting data to the app.
  • Check the alert thresholds set in the app to ensure they are configured correctly.
• Short battery life:
  • While designed for long battery life, extreme temperatures or frequent data updates might slightly reduce it.
  • Ensure you are using high-quality alkaline AAA batteries.
