Visited yesterday without charging.
5 spots reserved for charging in the public parking. The charging spots are probably also subject to the blue disc since there is no other signage.
There's also a 6th charger reserved for the Mobility car.
There's an error with the QR codes. If you scan the code it works, but if you follow the written instruction and type the provided code on the eCarUp website it says the charger doesn't exist. That's because they spelled Hofmatt with 2 "f" in the QR URL and eCarUp backend, but only with 1 "f" in the written text. It seems like the correct spelling should be just 1 "f" everywhere. I'll need to see if I can find who to report this problem to. In any case they should re-print the stickers, either with double "f" everywhere, or fix it in the backend and use a single "f".
EDIT: originally this post said the error was with the number of "t", but that's incorrect. The error is with the number of "f".
