Essential load power goes negative???
Does anybody else experience their essential loads draw being showed as negative? Mine consists of a wireless router and some disk drives - so nothing that could generate power. It seems to me that a measurement error is the only explanation.

Yes, my essential load graph bears very little relationship with reality. I get the strong impression that it's not a measured value, rather it's calculated or estimated based on other numbers. All that's connected to mine is a Raspberry Pi and a network switch - which obviously is a continuous small load, yet the essential graph seems directly affected by the grid load. During the overnight period when I'm charging the battery from the grid, the power consumption of my Raspberry Pi and switch triples. And if my car is charging as well, it increases tenfold :)
