I tried fiddling with it but didn’t get it to work before I lost interest 
HomeAssistant has similar integration using the API calls and although it worked, it never seemed to be worthwhile. BMW made changes a while back so you’d only be able to retrieve the car’s position when it was parked, so you couldn’t use that for position tracking. You could still get the state of some things, like whether the doors were locked or the windows are down, but that didn’t seem that useful to me.
What I miss is the old Smartthings app that ran in the car and detected when you got close to home so you could open the garage, etc.
