This location is visible in the Plug'n'roll app as active, in the Swisscharge app as inactive and not visible on opendata.
The coordinates and the address don't seem to perfectly match, it's a few buildings over. The depot visible in Google Street View appears very small, maybe there's some new construction in the area that looks like an empty field on those older pictures.
With 6xCCS 100kW and the name Postauto I guess this might be a setup used to charge their bus. But if they bothered to put it on Plug'n'roll they must have intent to open it to the public.
