I’d like to see this as well, since these devices are becoming more and more popular, and able to pull stats from the OBDII sensor… have to poke around and find the api.
Are you still looking for this? I am using that approach as a custom component, and I can try to dig up the Sync-Up client-id and client-secret if you want to give it a try.
Edit:
I have posted here the config what is required for SyncUp Drive.
And contacted the original author to move it to a custom_component repo.
