FMB003 deviceOffline

Hi all,

I have a question about some statuses our FMB003 modules send.

What does deviceOffline status mean? When is it sent? Sometimes this is last status I get and I get it live (not a cached status) so I’m confused. If it means device lost connection, how can it be sent?

Hi,

Good Day,

Could you please clarify the source of this information — whether it is coming from device logs or server logs?

Based on our observations, these events appear to be server-generated:

  • When no data packets are received within the configured inactivity/timeout period, the server marks the device as deviceOffline

  • When the next valid data packet is received, the server marks the device as deviceOnline

Thanks
AS.

Hi AS,

Thank you for answering.

You are right. This log is observed on traccar server. So it’s not recieved from device.

What I was expecting was unplug detection message but I’m not sure if I can get that. I set it to high priority.

Hi,

For unplug detection, please enable the feature from the Accelerometer Features section.

Set the following parameters:

  • Priority: High
    Detection Mode: Simple (this uses voltage-based detection)
    AVL ID: 252

After applying these settings, please test the behavior. If the issue still persists, kindly raise a support ticket for further investigation.

Thanks
AS
