Extended Characteristics in Eve (HS110)
How is Projected Cost supposed to work?

Mine shows 0 all the time when the power is off, and when on it shows a projected cost based on instantaneous consumption. I would have expected an average of last minute/day/week.
Is it because fakegato support is not yet added (issue #39) that these historical averages are not available and it's using the instantaneous values? 
Thanks.
