evcc: Sometimes the black visualization bargraph overflows to the right
Describe the bug
See attached picture, I think the upper brace (sun+grid) is shown correct,
but the green bar is too long. Green bar shows 1.8kW sun, but the legend on the left says only 1.5kW.
To Reproduce Steps to reproduce the behavior:
- I have attached below an dummy config file with static meter values which produce this bar situation for easy reproduction
Expected behavior I assume the green and the black grid power bars should be inside the braces, not one attached to the right.

Ahhhhhhh, mir schwant was. Das Log hilft, danke!
passend dazu zum selben Zeitpunkt der Log:
…
der Fehler im oberen Post war, dass ich 0W Hausverbrauch habe ? … wieso sollte das System sonst Strom aus dem Netz beziehen, zudem steht im Balken 200W obwohl aber über 700W erzeugt werden …
jetzt das selbe: es kommen 146 Watt vom Wechselrichter und ich beziehe 1274 Watt aus dem Netz, bei einem Hausverbrauch von (146+1274=) 1420 Watt (stimmt mit dem was ich am S10 ablese überein ! EVCC sagt aber ich habe “nur” einen Hausverbrauch von 1128 Watt …
The “fix” is wrong, see this image. “PV” is correct, “export” as well, “Verbrauch” not. The code is missing substracting export:
homePower := gridImport + site.pvPower + site.batteryPoweris wrong.site.gridPower und site.batteryPower waren vorher mit min(0, _) versehen.

Aber die Kombination von Akku-Laden bei gleichzeitigem Netzbezug bringt auch die Eigenverbrauch/Netzbezugsberechnung in der UI durcheinander.
