Had a 2017 LEAF, and could never get that app working.
Like once in a while it would show correct status, or sometimes it would start heating.
But mostly it just lied. Like I could stand next to the car, issue the heating command, wait a minute, force it to check the car's status and it would tell me the car was heating while nothing had changed with the car.
So yea, gave up on the app, didn't use it the last years I owned it.
That said, enjoyed the writeup, looks like a nice project and as a bonus I learned about some new tools.
