> I think this makes the case for, at least, a kill-a-watt style device. A whole home solution with sufficient report granularity and a report interface visible in the home would be worth the extra trouble, IMHO.
You can have per circuit monitoring, you need a CT for each hot conductor and a submeter with enough CT inputs for all of the circuits in your panelboard.
