Teltonika FMC003 OBD Params not recorded

michalis956 months ago

Hello, i have tried setting up fmc003 but it seems that many obdii parameters are not shown or not recorded. I cannot decode the hex string but the server logs do show "INFO" so it seems server can decode it. I am not sure if this is server issue or web app issue

Images and logs are here: https://drive.google.com/drive/folders/1-0kIGSh4UWZZf_Kj9erBuJAcQDA3Zbq6

From web interface logs an example:

864636062842287    teltonika    00000000000000440801000001900db486080013e348c014f0ff2b00c2000309000d000c05ef01f0011504c800450105b5000cb6000942381243100344000002f100006d611000001d7800010000693d

Why you cannot decode the HEX? I think Teltonika has a tool for it.

After decoding the HEX and looking again, it seems that the parameters come as "ioXX" which requires computed attributes to view. Are computed attributes logged somewhere, and can I view them in reports?

Computed attributes are just formulas. The output value is obviously included in the position, the same way as it was received from the device.

You didn't answer my last question. Is it viewable in the report?

e.g. Computed Attribute set up for Fuel:
Desc : Fuel level
Attribute: Fuel
Expression: io48 ? io48 : 0
Type: Number
Priority: 1

Linked to vehicle, shows up in popup.

In the reports -> Summary -> Columns I see Spent Fuel but that is empty.
Maybe because when the device is offline Fuel goes to 0? But in that case I should be able to see Spent Fuel as the maximum value, not nothing

I did answer. The answer was yes.
