Visited on July 29 and charged with Evpass RFID.
The first attempt failed with message "Hardware Problem - An diesem Ladepunkt wurde ein Hardwareproblem festgestellt", but I then tried again and it worked.
I reached the 165A limit, ~64kW at my voltage.
The position of the marker on Evpass and OpenStreetMap is wrong. The charger is along the southwest wall of the building. According to the maps, the street name is the same all around, "Allmendstrasse", so this doesn't help with location. I took a look at the parking to the north of the building where the wrong markers are, didn't see any charger there.
The Evpass picture shows the same actual location I found, but the "roof" on top of the charger and the EV symbol on the ground were not yet installed.
There is no indication on who can charge here. There's only the EV symbol on the floor and the Evpass QR code.
