Nice ideas, Dr. Ed, particularly the nice use of the comparator.  I'm
considering doing something similar here but under different
conditions.  We have a well (no current metering) and do home
automation mostly through an HAI OmniPro II.  I would "and" the away
flag so that monitoring is used primarily to detect leakage when we
are away from our home.  I.e., monitoring water flow to detect
constant low water usage or intermittent high water usage.  I already
have floor mounted water sensors in the laundry room and pump room.  I
guess I'll look to see what's available in low voltage water flow
sensors...

Best,
