Die Berechnung der geladenen kWh bei meiner cFos Solar Brain 11kW 2.1 (Firmware 2.10.0) ist falsch. Siehe Screenshot.

Ich habe mir das LOG von EVCC nochmal angesehen (siehe Anhang…) Auch wenn Start und Endzählerstand korrekt sind, scheint der Zähler der WB oder die WB selbst zwischen duch Zählerstände mit 0.0 kWh bzw. negativen Verbrauch zurückzumelden – siehe fett markierte Einträge

Offensichtlich gibt es Aussetzer beim Auslesen des INTERNEN Zählers (siehe Screenshots Zähler*.jpg… was ist hier zu korrigieren?
