While doing some data verification today I thought there was an error but it might have been a typo from me. The chargers are named "Säule 1 (links)" and "Säule 1 (rechts)", but I had written that there was a charger number 1 and 2, so for a second I thought the names on the sides were mixed up between ecarup and opendata. But the names on opendata actually match right now, so it seems fine.
I also checked with my closeup pictures from January, the connector named left had its QR code on the left and the right on the right, as expected.
