Here
are
a few ideas off the top of my head, none as simple as just setting a timer
when
the washing is put on, but I guess you are looking for something smarter
than
that. What about some sort of noise/vibration sensor, i would have thought
that
it would be possible to have a vibration sensor read every minute and when
it
stops reading report that the wash is finished (of course there could be a
problem if it is pausing between cycles, so maybe check for 5 consequtive
non-readings). If the machine has a see through window, then a PIR might
even
do the job, but I'm not sure about that. Final option is put a camera down
there and just check on the TV to see if it is done. Just one thing to
consider,
if there is an announcement, then what happens if 'wifey' (don't think I'd
get
away with that particular term ;-) ) doesn't hear it, what would be nice is
to
have an LED flashing on the comffort keypads (bit like if there is a
message)
as well.
