The chargers have been migrated to Shell Recharge backend.
Some chargers had Type1 connectors, I have no way to find which one those are in the new backend as Shell doesn't specify it, I'll need to check on location.
There are 2 groups of connectors, labelled S1 and M1 on the payment pages. I don't know if those reference mean anything or if they just had to limit the number of charger per pool.
There's something odd with the numbers. On opendata and Shell Recharge app, the pool numbers are 6203 and 10373. But on https://pay-qr.shellrecharge.com/ we are offered 10343 and 10373, and 6203 is absent. Pool 10373 currently shows unknown status everywhere. The other pools show available, but I'm not sure if they are referring to the same chargers or not. There were 21 chargers before, so there is likely no third pool as 10+11 is already 21.
