There are still no pictures or opening times for this location on Swisscharge at this time.
The &Charge pictures confirm this is an Alpitronic HYC_50 in the underground parking.
We also see there's a contactless reader with "coming soon" sticker on top. This was from January, it might have been enabled since then.
It's difficult to say for sure, but it looks like there are no gates for the parking, either free or parking meter?
On Google Street View, the pictures from June 2022 showed the parking was open 07h00 to 20h30, without any mention of weekdays. But the store is not open on Sundays, and closes earlier on Saturday, so I doubt the parking stays open longer if they manually close it.
