Visited today without charging.
The charger has been prepared for the switch to paid. If you try scanning the QR codes it redirects to https://www.lidl.ch/c/de-CH/e-ladesaeulen/s10023632 that says the chargers will be paid starting 2023-11-20.
The sticker on the charger says 60kW so I guess they are going to unlock the "full" power when alone instead of only allowing 30+30kW like before.
The charger is on opendata but incorrectly shows a triple plug setup.
