Check my project…Is the Swiss Knife for energy 
I’m so confused, how it’s necessary to explain. Any Energy distribution diagrams seen in PV EMSs show current energy rates. That’s what the moving dots are for. Building such a diagram with these dots and having them “show” how much energy HAS BEEN transported is a contradiction in itself. It literally shows CURRENT movement. Having overall energy also in there, but the diagram is about the current state. That’s why you have the current Battery % built in there. Whoever programmed this knew, that’s its not thoroughly consistent. Setting up a separate integration/addon to go the last few steps is such a mess.
