I’ll keep you posted here to see if the folks at Home Assistant have a solution. At the moment, the app isn’t working there either.
Edit 10.08.25
Home Assistant has released an update to the Hyundai/KIA app today. KIA still does not work. Unfortunately, I can’t say for Hyundai as I don’t own one of these vehicles. I drive a Kia Niro 2020 PHEV myself.
Edit 11.08.25
Today’s HA update was again unsuccessful. The error message is different: The vehicle is already configured
