RE: [Embedlets-dev] Re: X10 & JXME security

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

Dear Jac (and Ted) - Re: "I don't fancy working
while the lights switch on and off at random."

The nice thing about the X10 modules, is they will do it all on there own...
Trust me!

As I stated before... I would not trust'em to run a coffee pot. As you sit
there pondering that one, consider your house burning down... I vote for an
iButton DS1996 64kbit EEPROM RAM to hold my XML device and ID tags (sitting
in a Systronix 8x1-Wire board), and running CAT5 around the house (in the
walls) using Systronix 8x1-Wire boards and relays (which I am doing).  Bob
Hinton has a very nice "House Monitor" implementation for TINI (or TStik)
w/1-Wire devices that works great, is secure, and most important RELIABLE.

As an added bonus, you can try http://jackland.dnsalias.com:7080/milo.wml
from the WAP browser, on you WAP enabled phone. The access will be to Bob's
house in England.

You can go "browser direct" to:  http://jackland.dnsalias.com:7080/ , and
save the cost of a call, on your WAP phone.

Interesting (if you have noticed), is the URL for "jackland"... Bob lives in
Swansea, England - locally known as jackland".  Funny, 'eh?!? "Jackland" and
"JackNet".  Just a coincidence, but still, it's funny as hell!

I just checked the temperature at Bob's house:

Temperature readings at Tue Nov 18 06:31:24 GMT 2003
Fire Escape temp 19.5 C
Loft temp 19.5 C
Front room temp 19.5 C

He's closed a few windows (must be getting cold over) there:

House status at Tue Nov 18 06:46:32 GMT 2003
Kitchen door closed at Mon Nov 17 21:58:50 GMT 2003
Front room door opened at Mon Nov 17 19:42:17 GMT 2003
Monitor running at Tue Nov 18 06:45:27 GMT 2003
Loft power applied at Thu Oct 16 13:39:06 GMT 2003
Front bell push pushed at Wed Nov 12 16:50:25 GMT 2003
Front door closed at Mon Nov 17 20:42:34 GMT 2003

Best regards, Kelly (Don't waste your time on X10!) Smith

P.S. If anyone wants my rendition of Bob Hinton's "House Monitor" (some
thread bug fixes that I did), I will be more than happy to send you
HomeRun_1.12p9-0.2.zip for TINI/TStik.  Contact me off-list at:

Hmmm, at least some imho.

How would you like it when other people start switching the lights on and
off in the room you're in? At least some kind of validation to make sure
you're entitled to change the state of any X10 device would be a
requirement for me.
Not having some kind of authorisation would be a show stopper for the
implementation of this in my office environment. I don't fancy working
while the lights switch on and off at random.

Yes, no problem.

Regards,

Jac
