Or does it only track per circuit.
I rent out five bedrooms in my house. The other day I noticed a housemate with her window air conditioner on, the other window open wide. Last winter, another housemate had a similar thing going with the portable heater. I would like to know what all the various equipment costs me, who is leaving their heater on 24 hours a day even when they leave town etc. I have a Kill-a-Watt, but particularly for things in the bedrooms, I would love to know what’s going on without having to go in their rooms. The circuits weave randomly through the house, so it will in some cases be difficult to know specific appliances if that’s the only way.
Also, not clear what I should be buying. Do I need clamps as well and if so for what?
