Visited on August 10 and charged with Swisscharge RFID, no issue.
They erased the parking space numbers in front of every charging spot, so I think it's a clear indication you do not pay for parking while charging. I checked out the payment terminal for the other parking spaces, they cost 1CHF/h.
All the contactless readers on the chargers seem to be working. I checked the price on one, 59ct/kWh + 24ct/min after 60min.
Isabelle and Johannes are the chargers in regular "square" formation. Brigitta and Georg are the parallel parking spaces.
They already installed foundations to install 8 additional charging spots in the future.
I tried the parallel parking. The spaces are very long so it shouldn't be difficult to enter and exit. However the cable doesn't reach very far. I just barely fit within the lines when plugging in with a rear left charge port.
