eternal kernel
I have a energy panel configured with solar battery input and output entity (charge and discharge). Both are integral entities which have a total_increasing kWh counter (which is correct when looking at the history data of those entities). In the energy panel however i see a lot of negative input. Is that normal? i would expect battery input to a) only be positive [it charges] and b) be on the top side of the graph [since it consumes energy]
Is there something wrong here?
Thanks
Also my totals are completly messed up. FOr reference i have attached the solaredge monitoring view which looks more realistic

Yeah battery discharge should be on the top half of the zero line.
Share your .csv export file if you would like a sanity check

I think you're getting weirdness because the sensors don't add up.
E.g. at 10AM you have more energy going into the battery than all your inputs (grid input + solar)
This is impossible and it's confusing the graph

i see, could this be a integration issue?

hard to say
could be some sensors are time-offset, or you're measuring from the wrong place
at 12:00 you have 4kWh into the battery, but only 0.7kWh from solar, and almost nothing from the grid.
where's that energy coming from?

hmm i'm taking the numbers from the solaredge integration, so they should be the same
hmmmm then solar is missing somehow
in solaredge there is 4.7 kW for 12 am

ok, yeah that's the wrong sensor then for Energy Dash.

ok thx

ah i get what they do
this is tricky, they directly subtract battery charge from solar power
since they only provide flows into different systems, not absolute generation values
so they only provide solar => load or solar => battery
so to make this correct i would need to detect if the battery is charged from solar or grid
