Start Stop - Mileage trip

Mexxwelll7 years ago

Hello,

I would like to have the start and stop mileage to report in each trip. I have an Teltonika FMB001 device with OBDII support and this value's should be available.

Any idea of this is possible?

If your device sends those values, they are probably decoded as general IO values

I have an IO16 value that contains my total mileage in Meters. I have added an computed attribute that calculates the M to KM, but it does not show up under Total Distance.

Any idea?

Total distance is probably calculated after your computed attribute. Try using different attribute.

I will try to use the OBD Odometer attribute because thats the value. Can I edit the Trips report to add an OBD Odometer Start and Stop value? I cannot find any documentation on editing reports.

Why you don't want to use regular odometer?

Not sure, was thinking that value is comming from the OBD. I have changed it to the regular Odometer now:
Attribute: Odometer
Expression: io16 ? io16 / 1000 : null
Type: Number

How can I report those values on a start and stop on the Trips report? Any documentation regarding this?

It should use those values automatically.

I did some testing, but the odometer is not being updated with this parameters:

Attribute: Odometer
Expression: io16 ? io16 / 1000 : null
Type: Number

Do you have an idea why this is happening? Or is there somesort of logging of the applied computed attributes?

Can it be that I did not assign an computed attribute to my car? I just created under Settings -> Computed Attribute the 'Odometer' parameter. How do I assign the attribute?

Source: Computed Attributes

Of course you need to assign it. Select device, click on computed attributes in devices toolbar and then tick checkbox.

After assigning the Computed Attributes to the device I was able to calculate the Odometer status based on OBDII data. Only thing was I had to change "io16 ? io16 / 1000 : null" to "io16 ? io16 : null" because Traccar calculates the Meters to KM.

Everything is working great.

Thanks for your support.
