Is there a way to make the Energy Flow car bigger in the Energy Dashboard or maybe its own dashboard within it, like the others? I have so many power monitors I cannot read it.
Yes you can create your own dashboard with the card. Then set the section width to fill the screen then the card to fill the section.
Looks like there is no slick visual editor for the Water-Sankey graph and I do not know Yaml enough to get this right.
