Visited yesterday without charging.
The chargers can be accessed from the Schützenmattweg. There are 4 AC chargers in "front" of the garage under the roof. The DC and 2 other AC are in the "back" behind the carwash.
None of the chargers have any sticker or QR code, so I am not 100% able to confirm which of the AC chargers are the ones visible in the eCarUp app. Based on the coordinates and names in the app, it would be the 2 next to the gas pump under the roof. Those are the best signaled charging spots, with green paint, EV logo and letters "A" and "B" on the ground. There's no QR code, but the names "ABB 5 and "ABB 6" printed on the chargers match with the names in the eCarUp app.
In the back, there's no paint on the floor or anything. Like many other garages, they mixed the AC with the DC, leading to one of the DC being blocked over the weekend by a car that was plugged into the AC.
It seems like you could almost use the AC spots as a P+R, leave your car and jump onto the bus just a few meters away 😂 There's 1CHF/h in the eCarUp price (7.5CHF/h for DC), also indicating it might be open to the public.
