Visited on July 5 and did a short charge with Swisscharge RFID.
There are 2 spaces with very faded green lines and EV symbols.
The large ban sign probably applies to all parking spaces, regular and EV. Reserved 7h-20h for school usage during school days.
I had to wait for a few minutes on "Ladestation wartet Lastmanagement". Not great for such an expensive station to not even start immediately. Assuming they have solar, there should not have been the slightest power limit concern at that time of day.
It's not possible to reach the school through "Untere Zelg". Only access is from the east, as Mittelstrasse has been turned into a dead-end. Google Maps has no idea.
