What makes you think it's not supported? Does it use a different protocol format than other Teltonika units?
I have checked it in the traccar list https://www.traccar.org/forums/forum/devices/ and the device is not coming up.
I would recommend trying first then.
It is working all good
Hello, I can see that the Teltonika TAT140 is not yet added to the list. Can you please let me know when will the support be added for this device?
