Did someone already take a look at BMW's own HA integration? Currently that is only available for German users at https://labs.bmw.com/services/cba15ad5-ed53-4ad0-b8a4-6774b477eaf8
They do the integration backwards, there is some kind of stub custom component for HA that opens a websocket interface and then BMW tries to connect to that websocket from their server.
I can get the authentication to work, but then they do not find the integration on my HA.
