I think this would be awesome to develop a Tesla "skill" for. Since it's self-hosted, I don't have to worry about sharing my Tesla credentials with a 3rd party. I tried to create a quick and dirty Alexa skill to do things like check on the state of charge and lock the car, but didn't want to climb the mountain of storing "secrets" in Alexa/AWS. Keeping them local in Leon sounds much better.

I would also like to use Alexa to control my doors (garage, house, etc.) but making that available to world doesn't sit right with me. But with Leon I don't have to worry about someone hacking my Alexa account, or even sharing my credentials with a 3rd party "skill".
