Visited yesterday without charging.
The charger is in the parking spots accessible directly from the street. There is no spot reserved for charging, the parking is marked "nur für Besucher". So maybe you can charge outside business hours?
In Swisscharge app there is no picture and it says public, always open.
There used to be other Swisscharge connectors listed at this location, but it doesn't seem like they were from Energie360. There's a picture of the old charger on Chargemap, but it's not the same location. I'm not sure where that other location is because I didn't see any area that looked like that.
