5. Troubleshooting

If you encounter issues with your LEVEL SENSE SENTRY, refer to the following common problems and solutions:

5.1. Device Not Powering On

• Check Power Connection: Ensure the power supply is securely plugged into the SENTRY unit and a working electrical outlet.
• Verify Outlet: Test the electrical outlet with another device to confirm it is functional.

5.2. No Wi-Fi Connection (CLOUD LED Off/Flashing)

• Router Proximity: Ensure the SENTRY device is within range of your Wi-Fi router. Thick walls or metal appliances can interfere with the signal.
• Wi-Fi Credentials: Double-check that the Wi-Fi network name (SSID) and password entered during setup are correct.
• Router Reboot: Try restarting your Wi-Fi router.
• Network Compatibility: Ensure your Wi-Fi network is 2.4 GHz. The SENTRY may not be compatible with 5 GHz networks.

5.3. No Alerts Received

• Notification Settings: Verify your email addresses and phone numbers are correctly entered in the Level Sense app/web portal. Check spam/junk folders for emails.
• Thresholds: Confirm that your set temperature/humidity thresholds are appropriate and that the actual readings are exceeding them.
• Internet Connection: Ensure your SENTRY device has a stable internet connection (CLOUD LED should be solid).
• Cellular Carrier: For text notifications, ensure your cellular carrier supports EMAIL2Text Gateway (most do).

5.4. Inaccurate Temperature/Humidity Readings

• Sensor Placement: Ensure the sensor is not directly exposed to airflow from vents or placed too close to the appliance walls, which can affect readings.
• Sensor Damage: Inspect the sensor and its cable for any visible damage.

5.5. Alarm Sounds Continuously

• Check Conditions: Verify the temperature and humidity readings. If they are outside the set thresholds, address the underlying issue with your appliance.
• Silence Horn: Press the Horn Silence button on the device to temporarily mute the audible alarm.
• Reset: If the alarm persists after conditions normalize, try a soft reset of the device.
