Discoussion around handling meter transactions:
- we add signed meter value var to the powermeter
- the start transaction will return quick, would't wait for real walues
- we add optional start metr value, to sessionfinished event.
- the start meter value will be stored in the evsemanager, and published on sessionfinished event
- no changes to OCPP lib/module at the moment
Action Items:
- Janek: Update meeting time.
