Visited yesterday without charging.
These chargers appears in roaming apps with the name "PK Immo - vsao - MEG Lätternweg 29a öffentlich" (on Swisscharge it's cut off though because it's too long).
On location, the chargers have all the ChargeOne branding and QR codes, but there's zero indication as to who may park here. The parking spots in the street are blue disc, but those spots probably belong to the building we see behind.
