A Home Assistant dashboard card that turns your Energy dashboard into a living, real-time 2.5D view of what your home produces, stores and consumes, over the sun's daily arc. With or without solar panels.
Saw this on /r/homeassistant, thought it was pretty cool looking, even though I don’t have solar.
Panels are pretty cheap now, below €100 for 450wh panels.
It would cost around €10000 for me to get a system appropriate for my house. So it will take a while.
