FMM001 OBD Data

Hello,
I have verified that my FMM001 data is sending OBD data in the data stream it sends to the cloud. I verified it on GPS Gate platform. Could be a very basic question, how can I see the data on the traccar dashboard for the vehicle I have added on the traccar platform ? Do i need to enable something ? I have it installed on a Linux VM in a cloud platform. Could you please help ?

This is what I have at the moment

On your screenshot you just have the pop-up. Have you checked details? Green button.

Thanks for your reply Anton.

The graph shows the speed but not showing fuel level.
Do u want any logs from the server ? I can email you.

Hello Anton,

I think I understand now, the data is there. data.
But its not verbose. Its having some io48 etc. Which I think maps to a characteristic like fuel level. I am guessing this based on the value.
If my assumption is correct, how can we make the label human readable ?

You can use computed attributes to convert a generic IO value into something useful.

Thanks for the answer. Where can I find the list of the io numbers? E. G io48 means fuel level, etc?

Check with Teltonika. For most of their devices they post this info on their wiki page.

I use that calculated attribute and get that chart with FM3001 from teltonika

The 0.48 corresponds to the capacity of the fuel tank according to the manufacturer, in my case 48 liters.

I hope it is of help

Thanks Both, for anyone referring to the thread, here is the Link

Hello Anton, I have created the computed attribute, the test works fine too but I am not able to see that attribute on the details page or device attributes Link name Link name. Thanks in advance,

Have you linked it to your device?

Hello Anton,

How are you.

I have created a computed attribute for testing using the io69 OBD parameter I get. See this and let me know if that's correct. The test expression works fine too.

This is the raw obd parameter value

Making the connection with the computed attribute with the device
But Connection of the attributed with device is not saved

At the end, i am not able to see the description and custom attribute on the device details page.
Not sure what I am missing out.

thanks in advance.

What makes you think it's not saved? It doesn't show up if you click on the field?

When I got back to the device settings->connections->attributes and I click the drop down, I see the attribute but I don't see the attribute on the device details page. Is my understanding correct ? sorry if I am missing something. thanks

If you linked it, it should work.

By the way, null should be lower case in your expression. Maybe that's the issue.
