I want to add load control to my home automation system. (i.e. monitor my
electrical consumption and control my HVAC, clothes dryer, water heater, etc. to
keep my elecrical consumption below a threshold.)

Has anyone done this? If so, how do you sense your electrical energy
consumption?

The inexpensive way is to use an optical sensor that watches the disc spin
on your meter. There are a couple of manufacturers of this device. One was
called Power Sentry and featured in Home Automator Mag Aug 99, but it
appears it might not be available:

I'm just setting up the same thing, and the meter I am selecting has pulsed (opto isolated
I think - would expect it anyway) outputs and an RS232 output so I can use windows
software to monitor it as well. It also supports a modem for remote reading. Just have
to get the elec company to hook a modem up now so I don't have to let them on the property

I've seen that one if it's the one that goes between the meter and base. I
wasn't aware that was being sold to consumers. I thought it was just sold to
utility companies.

Its not an add-on. it is the meter, sold by e-mail australia and used by integral energy.
His unit is not normally used by consumers by they don't restrict it
