Apologies if this is really obvious, but I cannot fathom it out!

As an example, yesterday I had the following:

PV generated 56.7

Export 29.5

Import 63.4

Charge 30.5

Discharge 29.9

I reckon that my “load” should be total import (63.4) plus total PV (56.7) less PV exported (29.5) less PV put into batteries (13.1) plus discharge from batteries (29.9).

This is as close as I can get to House plus car load which would be 107.4

But the “load” quoted in the app is nothing like this at 82.9 ? Any ideas what this really is? What am I missing?
