Hi Stefan,
just read at this link, that the OCPP 2.0J protocol of the VW ID Charger is intended for backend communication: https://cdn.emea.vwapps.io/assets/f43da109-b109-4583-b248-cce6de477117/static/documents/VW_Wallbox_Manual_User_A_de.pdf
EEBus is defined as protocol towards the “Home Energy Management System”. But this is not available yet. Therefore I’m not sure if the OCPP interface would be available for my intended external access.
