The 2 ABB chargers don't appear to have migrated at the same time.
Et53*hu1*3218*018 was probably REPE201, because it was showing activity on Plug'n'roll right until the new one appeared on AVIA Volt.
REPE200 might have been out of service since December, as there was no live data available. Since May a second unit is finally visible on AVIA Volt, so I assume it's been either repaired or replaced. But with the 2018 manufacturing date in the serial, it's probably still the original.
