Best OBH2 for use with Traccar?
Have you checked Freematics?

I'm assuming you mean OBD2 because I don't know what OBH2 is.
I have just ordered 3 Freematics Traccar edition, because they are the ones you recommend.
I am looking forward to receiving them, see how well they work, and what data they report. I hope to see also the OBD2 data (fuel consumption, ignition status, speed).
Let's see if they live up to my expectations, have first configure them to report to my own prod server.
If they work well, we would be glad to support your project with some small donation too.
Which is the best OBH2 tracker that can be progammed to use the traccar server. Most I find is locked on their own paid or free webservice.
