Hello
I have Tibber and the polstar add on in Tibber.
It would be good for me to be able to see in home assistant the what charging state is for my Polestar. Then Ican calculate the amount of time needed for a fullcharged battery. Additionally my script will be more effective when choosing the time to charge. If for an example 2 hours to charge full, then my script will look for the 2 cheapest hours. Today I have a static value 5 hours and that not perfect
Until Polestar make the API public, the closest you will get is with the CSV app, or some hacks using tasker etc. The German Polestar forum is the best place to look (with Google Translate) as that is where the most activity is taking place.
