Visited today and successfully charged on the connector to the right.
The charger was recently installed. There's the EW Kallnach logo on the screen but no other signage so of course other vehicles were parked in front of it, making it harder to find. No idea whether additional signage is planned.
If they don't plan to reserve the parking spots, the placement isn't very good. They should have placed it further to the right so a greater number of parking spots could be reached with a cable. Being at the end of the row reduces the number of options.
For some reason the status was showing "occupied" in eCarUp app but was stuck for a long time at "unknown" on opendata (usually it only stays "unknown" while eCarUp shows "connected" before charging). But tonight I see a session was finally showed in the opendata live data history so it must have caught up at some point.
After starting the charge I did not have access to the stop button and session stats in the eCarUp. In fact, I don't have any record for this charging session, so starting a charge might have actually triggered the free vendor mode 🤔
