Hmm.  Sounds like Mr. Houston still can't disagree without resorting to childish taunts.  Most people stop making fun of other
folks' names when they reach middle school.

[sigh]  Let me try to explain this in simpler terms.  Imagine for a moment that Mr Houston's suggestion (made without benefit of
ever having seen, let alone tested Z-Wave) that this system can only travel 25 feet per hop.  If the controller is in the middle of
the home that's 100 feet in each direction.  You now have a maximum coverage of 200' in any direction.

Houston's idea that 217 additional nodes would all be unable to reach the controller assumes that al;l of them would be placed
beyond the 4-hop limit.  This would be true if they were all installed in a line.  Perhaps Mr Houston is accustomed to homes that
are ver-r-r-r-ry long and narrow.  :^)

Mr Houston is trying to force an erroneous conclusion by assuming that all nodes in a system are located in a straight line,
separated at 30' intervals.  The typical installation has nodes scattered throughout the home, each taking whatever is the optimum
rout from its location.

> This is the best case scenario...

Actually, it is a for all intents and purposes a non-existant worst case scenario based on a layout that would almost never exist in
a real world app.  I suspect Mr Houston knows this but he's so hell-bent on villifying Z-Wave that he insists it is normal.

Radio RA's repeaters repeat the signal after they receive it, just as all receivers do.  Nothing is truly instantaneous.

Interestingly, the makers of Insteon came out with this after Z-Wave did the exact same thing.  The difference is Insteon suffers
from lots of problems which have been enumerated here and on various message boards.  Z-Wave is more robust than Insteon, has better
support (well, if we don't count Dave Houston) and is more likely to still exist 10 years from now.

Schoolyard insults stop bothering most people me around age 13.  Come to think of it, most people stop making schoolyard insults at
about age 13.

I can't.  I need it every time Mr. Houston posts.  :^)
