Registration of hours in Traccar

I have a couple of cheap GPS trackers that look like relays and they seem to work fine, but they don't count hours in Traccar. Is there something wrong with the Traccar server or the GPS?

Do they report ignition or hour values?

There is no ignition current on them, only plus and minus, but in Traccar they do show ignition, but it is never on.
Total distance is shown, but not time.

I can enter how many hours the machine has been running, and then it is shown, but the time does not change when the machine is running.

If the ignition is never on, that would explain missing hours, right?

Yes it could be

It's just funny that there is no ignition on the GPS, but Traccar shows ignition under status

I don't know why it's funny. It's probably just a flaw in the device protocol where it always includes ignition.

Yes ok that must be what's wrong here.

Thanks
