Visited on Sunday without charging.
The DC charger is to the north of the property. The AC chargers are in front of the building under the roof.
While reviewing my pictures I notice the car to the right of the AC chargers has a cable plugged in. I didn't look where that cable was going, it's not plugged into the public station.
Both AC chargers have their eCarUp QR codes displayed. The DC charger however only has a single giant QR code that points to CCS #1. If you want to use CCS #2 ad-hoc, too bad I guess 🤷
There's no other information apart from the QR codes. I guess anyone can use them, at least the DC charger which is more separated. The AC chargers right in front of the garage are likely to have vehicles parked on them.
There's no gate, it's easy to access both areas. On the same property there's also a gas station and car wash.
