Visited yesterday without charging.
It's one of those mysterious eCarUp locations without any clear name or description, yet it's open to roaming and appears in all charging apps.
It's just named "Carport". The eCarUp app gives an additional description "Stuckimatte WohnenPlus" and an owner "Stucki’s Söhne AG"
The (building?)/(area?) has a website https://www.stuckimatte-wohnenplus.ch/ but I couldn't find any mention of the charging station there. Conveniently, there are many pictures of the building, but none of the covered parking area.
I found a charging station at the given coordinates, it's under the second carport on the left. Most parking spots have a plate number or name, but the spot that has the charging station just has a blank sign without any text. The charger has no QR code or instruction.
All parking spots under the carports are narrow and there are lots of pillars to watch for.
