The "app" they provide is 60% advertisement, 30% features, and I unironically preferred using a Home Assistant connection instead of of it for everything. Even for automations like "when to preheat the car", since that was easier and more intuitive outside of their native function.
This also means, that charge control from the cars side is not possible to automate anymore.
Sure, one could take the position "but it was never officially promised", but for some people, including me, having the api (which is paid btw) was a selling point.
Yes, I registered specifically for this comment.
