*RemoteStartTransaction*. Will successfully start new transaction. Call RemoteStartTransaction by server
will result in StartTransaction and multiple MeterValues to be sent to central system.

*RemoteStopTransaction*. Will stop running transaction.

*GetConfiguration*. Return charge point configuration.
*ChangeConfiguration*. Change charge point configuration.

*ReserveNow, CancelReservation, Reset*. Return 'Accepted', but do nothing.
