Consumption of grid power
I have a new installation of a 12K Unit but not sure if I am saving on grid power.
Is there a way to see how much power was used from the grid over a period (daily). Ive been looking at the "Operational data) spreadsheet which gives a lot of info but cant tell which column (if there at all) would display this info.

There is always your main electricity meter, which should be more accurate.
