I had some trouble finding this charger, but actually I think that's because it kept moving around, for real!
In my archived copies of the ChargeOne payment page, I saw:
On April 5, at coords 46.700659,7.892375 ("Aelmetli" parking) "Gemeinde Ringgenberg" Hauptstrasse 128, 3852 Ringgenberg
On April 25, at coords 46.699443,7.890413 (at the school) "Burgweg Ringgenberg" Burgweg 239R, 3852 Ringgenberg
On May 8, at coords 46.698786,7.887388 "Mobi-Charge - Gemeinde Ringgenberg - Parkplatz bei Burgseeli" Burgseeli Parkplatz 0, 3852 Ringgenberg
Today Swisscharge still called the location "Gemeinde Ringgenberg" from the first location, but the address and coordinates point to the third location.
When I had made my note to visit this location, I had written down the school address. I had not even realized this was already its second address. So I didn't stop at Aelmetli. I stopped at the school, but could not find any trace of a charger.
I then checked the apps again and saw the most recent location in the big public parking. I had trouble finding the correct exit off the main road, but I finally found the charger here!
The ground is not painted, but there are 2 "E-Tankstelle" signs. I would have preferred an unambiguous sign with the official EV logo and and a ban sign unless while charging.
