Missing io values from teltonika device (FMB001)

I tried to get the "fuel rate" from a FMB001 teltonika device (io60) but could not find it in the cars detail page / database.

So i parsed an entry from the server log where IO60 definitely is present.

Does anyone have an idea why some IO values are not parsed by the server?

many thanks in advance

Traccar parses all IO values. If you don't see it, most like you're not looking at the matching records.

As i only have 1 device connected to the server i consider seeing all io values ever being transmitted from this 1 tracker to the server in the details page of this tracker.
At least 1 value for io60 has been sent (proved by decoding raw data) , but it does not show in the device details page. Do i misunderstand something here?

thanks in advance Anton

At least one value? We don't copy values if they're missing by default.

Well i didn't parse all log entries ... just picked 1 and there was an entry for io60. I don't think this is just good luck.
I could decode more log entries but this would be sort of timeconsuming ;).
Do you have a command line tool or similar to make decoding more comfortable? Doing it manually is sort of a pain

Does this also mean that if you see an io value only for - lets say - x times or less they are not copied to DB?
Seems strange ...

regards

Copied to DB? I don't understand what you mean by that.

You said "We don't copy values if they're missing by default." ... thought you meant copy to database ... so maybe you meant copy to UI? The question is what do you mean by "Don't copy values" ?
Or to be more clear: What does missing by default mean? How often do they have to be present to be handled?

I mean copy from one message to message. For example if last message had io60, but the current one doesn't, it's possible to copy it over, but that's not enabled by default.

I see ... thanks for clarification.
So is there a way to extend logging to see the io60 values when they occur?
The log only shows the values for:
lat: 48.27141, lon: 13.76020, speed: 34.0, course: 357.0
although there are lots more

I am sorry ... just found the documentation for traccar logging

<entry key = 'logger.level'>fine</entry>

i will try this ...

just found the documentation for traccar logging

Don't do it. It won't give any useful information, but you will get a lot of garbage.

Thank you for the warning. I just reverted the changes ;)
Any other way to shed light on this?

There are many things you can do. You can configure attribute copying. You can enable raw message storage.
