My METOS Device Stopped Working – Troubleshooting Guide

Modified on Thu, 26 Feb at 3:55 PM

This article provides a clear checklist to diagnose and resolve issues when a METOS device stops sending data or stops operating.

1. Check the Battery Voltage

A stable battery is essential for the proper operation of your METOS device. You can verify the battery level by:

Checking voltage using a multimeter - LINK
Running a sensor test
Reviewing the last reported voltage values in FieldClimate

⚠️ If the voltage is below the recommended threshold, recharge or replace the battery - LINK
⚠️ If voltage drops significantly after sunset (for example, 6.7 V → ~6.2 V), the battery may be worn out and should be replaced.

➡️ A depleted battery can occur for several reasons. The most common causes are a solar panel being shaded or not detected, and/or network issues that cause the station or modem to hang.

2. (If Not Using a METOS SIM) Verify SIM Card & Network

If your SIM card is from an external provider:

Confirm that the SIM has active mobile data
Check that your location has coverage for the network supported by your device
Review the compatible modem/network list for your METOS model - LINK

3. Reboot the Device

A full power reset may resolve firmware or transmission issues:

Disconnect the battery
Disconnect the solar panel
Wait 30 seconds
Reconnect the battery, then the solar panel

➡️ The METOS 5 features with a SWITCH button underneath the motherboard box.

4. Check the Firmware Version

To ensure stable operation, confirm the firmware version:

Go to FieldClimate → Device → Information
Check the Firmware Version label
Compare it with the latest version available for your model - LINK

➡️ If your device is not up to date, update the firmware using the appropriate model‑specific link:

METOS 5 – LINK
iMETOS 3.3 / ECO D3 – LINK
uMETOS – LINK
nMETOS – LINK
Camera family (iSCOUT / CropView):
- Camera – LINK
- Control Unit (ECCU) – LINK

⚠️ Please note that updating the Camera requires updating the Control Unit (ECCU) as well; otherwise, the camera may not function correctly.

5. Generate a Log (If the Issue Persists)

If your device still does not operate correctly, create a log and attach it to your support ticket.

METOS 5 – LINK
iMETOS 3.3 / ECO D3 – LINK
uMETOS – In Progress
nMETOS – LINK
Camera family – In Progress
