Not Receiving Telemetry Data

[Spacefreak18]

I'm having some trouble getting this to work.

I had to force certain versions of the dependencies, that wasn't much of an issue.

It could be that I'm running AC and not ACC, I wanted to atleast get something to work, they use the same file names, but the structures are different.

Hi there!
I once added some stuff to read files created by the ACTI plugin for AC. But I didn't maintain it further and I'm sure that this is broken now due to changes in other places ... Did you also use this plugin or s.t. else? Could you maybe upload your files somewhere?

[Spacefreak18]

I too was thinking about adding Motec support. Were you able to get good results, and did you find decent documentation on the format? Because it seems to be the closest there is to a "standard" in telemetry files.

I have gone a different direction, currently I created a basic python tool that will send data to an influxdb for use with Grafana.

I did not find any documentation so I reverse engineered the Motec data-format, that is what ldparser (a submodule of the tool here) is supposed to do. I think the ldparser should also work with data from AC (or ACTI ...).

Your approach with influxdb/grafana sounds interesting, I'll check it out when I get the time. In fact, I did s.t. similar, just sending the data to a mongodb instead. But this project I didn't publish so far ...
