The Zaptec Go 2 lacks an "Autostart" option in local OCPP mode, so I enabled "Start remote transaction on vehicle connection" in the wallbox settings of evcc.
While the first charging session works correctly with the RFID-Identifier showing as "evcc", authentication fails for every subsequent vehicle after unplugging. The RFID-Identifier remains empty and charging will not start, even when set to "Fast" mode. The only way to start charging again is to restart evcc.

Description
The Zaptec Go 2 lacks an "Autostart" option in local OCPP mode, so I enabled "Start remote transaction on vehicle connection" in the wallbox settings of evcc.
While the first charging session works correctly with the RFID-Identifier showing as "evcc", authentication fails for every subsequent vehicle after unplugging. The RFID-Identifier remains empty and charging will not start, even when set to "Fast" mode. The only way to start charging again is to restart evcc.
