Unterschied in Stromverbrauchsmessung - Evcc/Go E-Charger Gemini Flex 22kw v4

Describe the bug

Hi, ich habe seit kurzem Evcc mit einem Go-E in Betrieb und habe etwa 6-7% Unterschied bei der geladenen Energiemenge. Zwischen den in Evcc angezeigten Ladevorgängen und der Go-E App.

Mein Setup: Raspi mit IoBroker und Evcc Solaredgeanlage eingebunden über ModbusTCP Go E-Charger Gemini Flex 22kw v4

Der Go-E ist erst seit 10 Tagen in Verwendung und wurde von Anfang mittels Evcc gesteuert - also also beide jungfräulich und Zählerstände waren bei 0!

Nach nun 13 Ladevorgängen - teilweise recht kurze mit geringen PV-Mengen steht nun der Gesamtzähler in der Go-E-App bei 180kwh. Evcc hat mir unter den Ladevorgängen allerdings 169,7kwh als Summe ausgerechnet.

Da es sich um ein Firmenauto handelt und ich den verbrauchten Strom ersetzt bekomme, wärs natürlich toll wenn Evcc zumindest nicht nach unten "streuen" würde... :-) Bei ungefähr 6500kWh pro Jahr fürs Auto wären das fast 500kWh Abweichung...
