Troubleshooting connection issues for the LoRaWAN Sensor

Troubleshoot connection issues between a LoRaWAN Sensor and the iQ platform.

Use the following steps to see whether the issue with the sensor relates to:
  • Power and installation
  • Sensor activation
  • Network coverage
  • Gateway connectivity
  • Platform configuration

Before you start

Make sure:

  • The sensor is correctly installed in the cooler.

  • The sensor has power (battery is installed and not depleted).

  • A LoRaWAN Gateway is installed and powered nearby.

Troubleshooting steps

1. Check sensor power and status

What to check:

  • Is the sensor powered on?
  • Is the battery correctly installed?

What to do:

  • Remove and reinsert the battery (if applicable)
  • Confirm the battery is not flat
  • Check for any LED indication (if available)

Next step?

  • Sensor powers on? Go to Step 2
  • No power? Replace the battery or sensor

2. Confirm the sensor is activated

What to check:

  • Has the sensor been commissioned or activated?

What to do:

  • Verify activation using the AoFrio Field App or installation process
  • Confirm the correct device was selected during setup

Next step?

  • Activated?  Go to Step 3
  • Not activated? Complete commissioning process.

3. Check signal strength and placement

What to check:

  • Is the sensor within range of the LoRaWAN Gateway?
  • Are there physical obstructions (metal panels, compressor units)?

What to do:

  • Move closer to the Gateway and check if connection improves
  • Reposition the sensor:
    • Avoid full metal enclosure zones where possible
    • Use recommended mounting positions

Next step?

  • Signal improves? Installation positioning issue resolved
  • No improvement? Go to Step 4

4. Confirm Gateway connectivity

What to check:

  • Is the LoRaWAN Gateway online and connected to the network?

What to do:

  • Check Gateway LED status indicators
  • Confirm the Gateway is sending data to the AoFrio platform
  • Verify other devices are successfully reporting

Next step?

5. Verify device assignment and configuration

What to check:

  • Is the sensor correctly assigned in the platform?

What to do:

  • Confirm the sensor appears in the correct location (site/cooler)
  • Check that the device is linked to the correct Gateway

NOTE: Some configuration details are managed at an administrative level. If you are unsure, contact your system administrator or your AoFrio Customer Success Manager.

Next step?

  • Configuration is correct? Go to Step 6
  • Configuration issue continues? Correct assignment or escalate

6. Check data reporting

What to check:

  • Is the sensor sending data?

What to do:

  • Review recent data in the platform
  • Check last communication timestamp

Next step?

  • Data present? Issue resolved
  • No data? Go to Step 7

7. Escalate

If the sensor still does not connect, provide the following details to your internal system administrator or AoFrio Customer Success Manager.

  • Sensor ID / serial number
  • Installation location
  • Gateway ID (if available)
  • Description of troubleshooting steps completed
