Visited on July 5 and did a short charge with eCarUp app.
All chargers visible on eCarUp are in the area that isn't fenced off in front of the showroom. The only access is from the backroad on Neuweidstrasse, you then go up a ramp and end up back at the main street level.
The DC charger is alone on the showroom side with 2 blue spaces that were kept free, but are not otherwise indicated for charging.
The AC chargers are along the railing. They still have their eCarUp QR codes, but they must have been made private in the backend because they have not indicated working on eCarUp for a while. But clearly they still work and are being used internally.
