3 days ago Two pretty easy options here. First, you can do a weighted average of COP using power as the weight. Or filter for times when the mode isn't Off.
I believe we already have a flag to report COP and SHR at each time step too, show_eir_shr. Should be in the docs.

It looks like hourly COP outputs are averaging all the 0 values when equipment is off, not just when COP is actually being calculated, leading to crazy low hourly values.
This is just a reporting bug, but when we do hourly averages for things like COP, we should see if there's an easy way to exclude 0s from the average, so we can still report something useful. As it is it looks like a ASHP is very inefficient if you just look at hourly COP results for heating/cooling.
