If it uses the standard Teltonika protocol then yes.
Yes, it does. However the Decoder needs a lot of work still to recognise the various models and do correct decoding of parameters. I would recommend you list the model of the device as FMC920.

This device uses the ´codec 8 extended´ protocol by default and according to chatgpt Traccar does support it. Anyway, I decided to get my hands on the device. Meanwhile, having tried every possible configuration in Teltonika configurator, Traccar simply does not seem to work with this device at all. Another tracking platform(ruhavik) works like a charm. But it is of very limited use, so I would definitely prefer Traccar and have my tracking on-premises. So far sharing my testing efforts to get this device work under Traccar. Maybe I could somehow help improve this device support?
Do you have logs?
Hello,
Does Traccar support Teltonika FMC880 ?
Best regards
