EV charging station (EVCS NS) - how to extract all previous charging session data

Q&A and troubleshooting EVCS
1

I need to extract all previous charging session data from the EVCS in order to claim petrol costs (:)) from leasing company.

What SW do I need to install on an RPi, how do I connect it to the EVCS and what kind of script will extract that data?

Some ideas depending on you situation:

  1. install https://evcc.io/ so get more functionality for dynamic pricing and planning. (just has a download button for charging sessions)
  2. Home-assistant or influx db and record, but needs additional data processing.
  3. Maybe you can enable data collection on the VRM portal for the EVCS, but I do not know if you will get charging sessions or overall kWh charged.

Hope this helps!
