The markers for chargers 7 through 11 have been moved to coordinates 47.3748773,8.23028059. There seems to indeed be a Lyreco building there. But the address for the plugs still says Riedstrasse 4 "Ditikon". Hard to tell if that's a misspelling of "Dietikon" or "Dinktikon", but the new location definitely has no Riedstrasse.
Those charger didn't exist when I visited the location in Dietikon in August 2023, so I can't say whether the charger were ever physically present at their old location.
The payment page still names them 7 through 11, which followed the 5 and 6 I had seen in Dietikon.
