I'm still thinking about adding a current sensor to each branch off my main panel so I can not only have a whole house electrical consumption but drill down to each branch and see what's eating all that energy. Very simple and cheap coils around the wires type of arrangement, probably with a multiplexed ADC, and some arrangment for measuring the voltage of the two phases relative to neutral so I can find power factor if I'm interested. But it's yet another project I'm not going to get around to this year. My meter spins awfully fast, though... Flow meters for water and gas aren't so cheap or trivial to add, though, so I think I would just monitor them with the utility's meter. -Adam -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Moving in southeast Michigan?
