Visited on November 27 and did a short charge with Swisscharge RFID, no issue.
Parking seems to be free. I didn't see any time limit either.
Number 26 is on the left, 27 on the right. Confirmed as the QR code placement and by looking at the live status while charging.
I was only getting 3kW, confirming there's a 16A limit even when using a single phase.
