Visited on June 10 without charging.
The charger appears operational, networked through ChargeOne.
For some reason, BKW renamed the EVSEIDs of the fast chargers at Volvo Häusermann in Wohlen, so that they could re-use the same EVSEIDs here. The only reason I can think of is that they didn't want to, or couldn't order new fancy QR codes, and they still had the ones from the Volvo garages that were never installed in a drawer somewhere.
The stickers / metadata appear to be incorrectly applied between this location and Parkplatz Rosenmatt. The QR codes I found (CH*ONE*E8D0268*001 left, CH*ONE*E8D0269*001 right are named "Parkplatz Rosenmatt" on the payment page and appear in the other parking in roaming apps). Unfortunately I cannot tell for sure what is wrong, see my report on the other station for the failed test there.
