Ed, I have one last question regarding the current sensor. As the washer progresses thru the wash and spin cycles, does the washer's current ever drop below the detection threshold of the CR9321 current sensor (350mA)? For example, just before the washer starts the spin cycle, I would guess that the only power usage is the small timer motor. Likewise, my washer has a "soak" cycle when the clothes just sit for a few minutes without running the agitator. In both cases not much current is being drawn by the washer.
If the timer motor draws over 350mA, then the CR9321 should work great, otherwise the Ocelot will have to time the periods when no current is detected to determine when the washer has acually finished.
