Visited today without charging.
I can confirm chargers 1-4 are on the roof in place of the old free chargers. Previously the free chargers were easee units, now replaced with the usual Zaptec.
Chargers 5-8 are on the ground floor in front of the entrance where the other free chargers were. Here we had evbox chargers, now also replaced with Zaptec.
It seems like the parking is open around the clock, but it's not really advertised as a public parking. I regularly see chargers occupied outside of the shop opening hours. On the price sheet it says "Tarif: Montag bis Sonntag". There is no mention of daily maximum or night tariff so I suppose it just continues at 2 CHF per 30min.
There is a sign "Der MParkPlatz wird 1/4 Std. nach Ladenschluss geschlossen at the bottom of the ramp. Maybe it's only the rooftop parking that closes with the shops? 🤔 I'm also not sure if the rooftop is open around the year or if they sometimes close it for weather.
Regular parking prices 1h=50ct, 2h=1CHF, 3h=2CHF. No free period here.
