Going through all the data I have for the Lötschental, I think 7723005_001
might actually be the charger ID.
It's on IchTankeStrom, but its position is to the east of the village, in the middle of the road somewhere there is no house or parking on the satellite images.
The name on IchTankeStrom is "Parkplatz Silberdistel", but I am unable to confirm where that parking is/was. In the EasyPark system, the parking in the middle of the village where there is a confirmed charger is named "Postautohaltestelle Blatten Dorf" (391910). On Parking.ch, it's called "Parking Faflerstrasse". I can't find anything named "Silberdistel" in that valley.
The live data for charger 7723005_001
shows it went out of service on 2025-05-28 around 16h, so it must have been within the evacuated area, and likely lost power / network at the moment of the disaster.
I also cannot find any other green parking spot on the satellite images, so I think this must be the same charger.
