Visited yesterday without charging.
Parking is free, closes with the shopping center. There are no gates.
The charger is in area B, after the turn in the corner when driving in the row to the right of the entrance.
It has the QR code and seems to be working fine.
OIKEN/Migros Valais seems to have always picked the strangest spot possible in each of their parkings. This one isn't too bad as it isn't next to a pillar, but there's a trick with the wall on the side of the parking spot only at the back, and the back wall is angled compared to the parking spot.
It's crazy they never installed more chargers with OIKEN here, 1 seems to few. But M-CHARGE appears to now be taking over with 8 DC chargers under construction. I created a new marker for M-CHARGE on the map.
