Note on new feature UserNotification by email #1916
Description
I really like this new feature of notifiing people about charging tranactions. Something many of our user asked for.
Situation:
- User authorizes vie RFID at charger
- first notification ocppStationStatusSuspendedEV is send
- User plugs in the charger cabel
- notification ocppTransactionStarted is send
- car reached desired charge level i.e. 80%
- second notification ocppStationStatusSuspendedEV is send
Question:
Why does SteVe send an ocppStationStatusSuspendedEV email after authorization?
From the user's point of view, this is not logical. Could that first notification be ommited?
This is a corresponding log for such a charging transaction.
