RE: [Embedlets-dev] X10 and 802.11

[Kelly S. <be...@ea...>]

Dear Ted - I can zip my entire "X10 Home Controller Escapades" into a rather
large zip file.  This includeds the DalSemi/Motorola demo of using
Motorola's iDEN phome to communid=cate to an X10 power module via a TINI
with a CM11A and a servlet from a PC.

I also have a complete disporation on how to "Bullet Proof" the wiring in
you home that can somewhat minimize the erratic behavior of the AC wiring...
Keep in mind that every home will be unique.  I had lights going off and on
"Just for the Hello of it" at sporadic and un-corralatble times eith the
TINI unplugged from the CM11A.  In short, people will be disappointed with
the results, and the TINI (at best) can only handle about four X10 modules
(on a good day, with no sun spots.  Real world applications with X10, that
might endanger the public, are out of the question.

In short, X10 is _NOT_ a predictable and "rock solid" solution, and there
are too many variables to contend with on a case-by-case installation in a
home (much less a large installation like an industrial control site).
Finally, TINI or TStik (at 1 MB) doesn't have the " grunt" to deal with many
X10's to support it.  I would rather bet on using 1-Wire devices and relays,
than go the X10 route (even if I do have to run some CAT5 cable in the
walls...  Conclusion:  X10 sucks!

Putting an X10 power controller on your spa, might be great for Lobsters
however. 8D

Best regards, Kelly ("Save the Lobsters Foundation") Smith

This has been my perception of X10 for a while now too and that is why I
have
not spent too much energy on X10 myself.  But it appears that the whole Home
Automation industry runs on X10 and so if we want to move Embedded Java into
this area it seems that we must interoperate with X10.


Here is a diagram of the current Home Automation scenario we need to deal
with:

I noticed that 802.11 is starting to be used as the means of integrating
more
sophisticated devices into the home and as soon as we start talking standard
internet protocols then Embedded Java shines.


All we need is a strategy for introducing Embedded Java into the Home
Automation space and I personally think that remote and secure access to the
home using any Java enabled cell phone is the easiest way to do this.


Web Services based Enterprise Outpost can not do this but a JXTA based
JackNet
Home Outpost can and that is one reason that I am devoting a part of my time
to
JackNet.
