According to ABC News, "The average
single family home was 2349 square feet in
2004"

That is roughly the theoretical limit with
four hops and the controller located in
the center.  If the house were round,
it would be more.  Given four 30' hops
we have a radius of 120'.  You do the
math.

Wrong.  His home isn't a test of your
ill-informed theory.  It's a successful
application of Z-Wave in a home that
is slightly larger than average.

You've implied that it is grossly ineadequate
for all but the smallest homes.  You were
wrong.

That is far from the *only* statement you've made.
You have repeatedly claimed (without benefit of
experience) that Z-Wave is inadequate to the task.
The gentleman's application, along with numerous
others, shows you were wrong on that count.

You've insisted that it would never take hold --
this despite the more than 100 companies
backing it, including the likes of Intel.

All syetms have a limitation.  Z-Wave is capable
of automating much larger homes than you
imagine.

Wrong again.  It's 8.  The supplier is InTouch

Precisely.
