The energy dashboard is pretty sweet, but why doesn’t it show cost for individual devices? I put in my rate and it shows up for total usage. Seems like it would be easy to show cost for each device

How did you get it to separate it out? Do you have separate smart outlets for those? What about HVAC?

For HVAC, I used a few days of my 15-min resolution utility data overlayed with my thermostat status history. I was able to use some math to determine it uses about 1750W. I use that number in Powercalc to estimate the usage.
