Visited today without charging.
The chargers are attached to a lamp post along the blue parking spots.
There are slots in the pavement which I assume are meant to host the charging cables to people don't trip over them on the pavement.
On MOVE, IchTankeStrom and other roaming apps there are 2 pairs or IDs. The IDs that appeared later have always shown unknown status. Usually this happened when they were about to swap chargers but the "new" IDs have been visible for a while now and still not operational. On the charger there are QR codes for the "old" IDs and they still seem to be the ones in use.
