[FEATURE REQUEST] Add Grid to Battery Flow

[sammort]

Is your feature request related to a problem? Please describe. I often charge my battery from the grid when cost is cheap. It would be great if the power flow card reflected the flow from the Grid to the Battery. At the moment charging the battery from the Grid will show the power drawn from the grid, the charging power at the battery and also Home will reflect the draw from the grid....this almost appears as a double counting of the grid draw as it is shown at both the battery and home.

Describe the solution you'd like

• A flow between Grid and Battery is shown on the card when the battery is charging from the grid.
• The power draw by the home doesn't include the power currently being provided to the battery to charge.

Describe alternatives you've considered No real alternative idea for this I'm afraid.

Additional context Current card shows battery charging but flow (and Grid draw power) is all shown to home

I think this can be seen as a duplicate of https://github.com/flixlix/power-flow-card-plus/issues/385 and https://github.com/flixlix/power-flow-card-plus/issues/444

Essentially Grid to Battery (and Grid to Home) will only display correctly if there is Solar production. For my system that is never the case and I believe a lot of users will have batteries which charge from the grid to take advantage of time-of-use tariffs.

same here, and the flow was there in a previous version..:
