I see that Dave's already given you the site URL.  Hopefully he will be able
to help us out at some point or even teach us how to do it ourselves!

Precooling is an excellent technique.  I monitor humidity and temperature
trends by eye and use strong ventilator fans to cool the basement and the
attic in the cool summer nights.  When I close up the house for A/C, it runs
far less often that way, as you, too have discovered.  There's so much
potential for smart homes to save so much money we could reduce our
dependence on foreign oil.  I really admire your setup - and I see where
automating those wireless thermometers will really be helpful in maximum
your efficiencies.

Lets hope that both of you live long and prosper.  COPD is real burden.  I'm
looking on Ebay for some oxygen bottle mounts for dad's scooter.  The Feds
would have paid $1200+ for a bottom-of the line scooter for him but I found
a much nicer one on Ebay for less than $150.

[/rant on] I think as the baby boomers and the even newer generations age,
they are going to demand power home windows, free air cooling and multiple
fuel heating plants with heavy emphasis on solar.  I need to automate my
Dad's home front screen door.  He gets bowled over sometimes when the screen
door slams into him.  I'd love to automate his windows but that's not going
to be easy.

I would have given up on HA long ago as too complex and too unreliable but I
am coming to understand that it's too indispensable to the physically
challenged for me to give up on it.  Anyone with any experience with
residential storm door openers, please chime in!

I know that if I live long enough, I'll have a lot of the same problems as
Dad so I'll need a lot of the same solutions.  What I didn't understand
until the "Ebay Scooter" project was how Mom and Dad reacted to their
illnesses, withdrawing more and more from the world as it became harder and
harder to move around in it.  Today, in fact, I went out to my folks to fix
a toilet, a blown antenna preamp and a faucet.  Neither one of them had said
that they had someone in to fix them, but they didn't do the job right.  I
wonder how many other elderly people just suffer in silence . . .
