zappi supports the OCPP remoteStartTransaction and remoteStopTransaction commands. These are typically used by OCPP services, to start and stop charging from a third party app or user interface.
When a remoteStartTransaction is sent, zappi will do two things:
- It will unlock the lock function on zappi, to ensure charging is allowed to start
- It will move zappi to the charging mode (FAST, ECO, ECO+) that you defined in the OCPPChargeMode parameter in the OCPP configuration.
If a user unplugs from the charge point during a transaction, zappi will automatically revert back to STOP mode, when the OCPP FreeCharging parameter has been set to False in the OCPP Configuration.
