Visited yesterday without charging.
The eCarUp app shows one charger here without any detail except the address.
There are actually 2 chargers. The second is in front of the Mobility parking spot but there's nothing written on the charger apart from the payment QR. If you try to scan the code it says the name of the charger is "Mobility" and costs 0 CHF/kWh. I assume it's reserved for Mobility but it's not really said anywhere.
I'm not sure the first charger is public either. The parking spots are marked "Reserviert - Mieter und Kunden Fliderweg 11".
