Visited on September 20 without charging.
They didn't do a very clean job with the migration to eCarUp. The QR codes are just pasted on top of the older ones, and they didn't remove the MobileCharge payment instructions. The sign can barely be read anymore, but at the bottom it still says somewhat clearly that roaming is not supported, which is not true anymore now that they use eCarUp...
I could not confirm that the IDs match to the exact chargers, but at least the QR codes are installed like described on eCarUp, with the "left" unit on the left and "right" unit on the right.
