I have solar, and my solar combiner box has solar production values (a positive value from 0 and up), and it has consumption sensor as well for total household power usage. This value is also always positive. The amount of power going back to the grid, if any, is solar production minus power consumption. However, as I read the sensors on this card, it will not support this configuration. It wants a consumption sensor that is both positive and negative.
I need a feature that will let me specify household grid consumption (always a positive number) and have the card do the calculation whether my net is pulling from the grid or sending back to the grid.
