Visited yesterday and successfully charged on the left connector.
The parking was full, all the regular spots were used and one of the charging spots was ICEd.
The only parking instructions are a truck forbidden sign and a "Richterliches Verbot" sign, but I'm not really sure if that's linked to the truck ban. If it isn't, I'm not sure who the parking is meant for, is that only for teachers of the school?
The charger being by Primeo I assume it's supposed to be public but the charging spots have no additional parking instructions apart from the EV logo on the ground.
The left charger was showing "unknown" status in the MOVE app and it was not possible to start a charge from the app. On the charger screen nothing indicated any issue. I tested the MOVE RFID and I was able to successfully start a charge. Charged at 16A/11kW (the max for my Tesla Model S) for a few minutes to test.
