Visited on April 6 without charging.
The 2 new charging spots are to the left of the existing ones.
When I was there the app indicated all available, but the new spots were fenced off because of the fresh paint.
I'm still very confused as to who the chargers are for. Based on the amount of signage it seems to be public, but the area in which the chargers are found is indicated "Vermietete Parkplätze".
The parking spots are numbered but I looked around and it doesn't seem like there's a parking meter or anything in this area. But there's a time component in the Swisscharge price so this could be what compensates for the "free" parking by being outside of the gate.
