Visited on May 19 and did a short charge with M-CHARGE RFID.
When I arrived, 3 of the 4 DC connectors were in use. The unfortunate thing was that both cars on charger 1 had finished charging, and I was forced to share charger 2 with another car actively charging, meaning we only had 30kW each instead of 60.
The AC chargers were installed at the planned spots next to the DC chargers. The 2 other spots planned for AC chargers on the other side of the wall were not painted in the M-CHARGE style, and the existing EV symbol has been erased. They didn't remove the "Hier dürfen Sie ebenfalls parkieren" signs though. I assume those "signs" are actually already the full M-CHARGE backplate with Zaptec mount point, because they are exactly the same size and the 2 active AC were installed at the exact place where those signs used to be.
The ParkingPay signs at the entrance to the parking are only for the area before the ticket gates. The chargers are in the Migros area behind the ticket gates. Payment is done with a ticket.
There's an EV symbol with an arrow just before the exit, but it doesn't really provide any value because at that point you have already driven past the charger and it's easy to guess you'll have to turn that way to reach the other half of the charging spots.
