Hi John,

We had this house built for us in 03, and don't contemplate another new
house for a loooong time.

I replaced every light switch that could possibly be automated with the
older 16383 & 16293 "red LED" Leviton switches.  These are now discontinued,
but I chose them because they had true rocker action, AGC, and still used
the code wheel switches.  I installed the small Leviton in-line filters in
every ceiling lighting circuit that could have compact fluorescent bulbs
installed.  The Ocelot runs the show.  We have a bunch of  palm pads and
mini-controllers for manual control.  I did use the BX24-AHT with a CM11A at
the old house, but here I'm just using a single centrally located RR501 for
the RF link.

We use thermistors to monitor outside and garage temperatures.  X10 controls
exhaust and intake fans to take advantage of cooler early morning
temperatures.  Sprinkler is a Rain8 controlled by X10.  Hot water
recirculation runs 75 seconds every 10 minutes during the day under X10
control.  We have a bunch of Leviton 16400 indicating switches spread
throughout the house to control things like all exterior lights, override
sprinkler cycles, trigger scene macros, etc.

The main panel is outside, and that feeds the major loads - A/C compressors,
stove, dryer.  And it has the disconnect for the internal distribution
panel.  I installed one of those Leviton whole-house blockers at the inside
distribution panel.  I placed all circuits that could possibly use X10
control on the same phase, pretty much eliminating any need for an active
signal coupler.  When the house was under construction, I had the
electrician route one circuit throughout the main floor to where we planned
to locate electrical equipment.  That includes the main PC, TVs, DVRs, and
even clock radios.  This circuit runs through a 20A X10 filter, and has the
provision to be fed via a large UPS should power become unreliable.

As I've mentioned elsewhere, reliability is well over 99.9% with hundreds of
commands sent daily.  One module is a little cranky and ignores its off
command every couple of months.  It feeds a CF light, and that may be the
cause.  All Leviton X10 switches have been 100% reliable since installation.

I did not use X10 for HVAC.  That's an 8-zone Carrier/Bryant Comfort Zone
controller with digital thermostats in 8 locations.  Security is also not
X10.  It's hard wired 16 zones with a intercom - pulled in almost 2000 feet
of wire for everything.

That's the long answer to a short question.
