Re: Suggestions for X10/Automation Widgets

Jeff,

There was an article in Nuts & Volts in September 2001 titled "Build the
X-Lock" by Jeff Mazur that was along the lines of what The Alien is
suggesting. It listened to the powerline and, when it heard an alien X-10
command, jammed it by corrupting the signal. It used a COP8FLASH µC.

The approach has the advantage that it works without modifying any existing
modules. It has the disadvantage that it will cause an eternal duel for
control of the powerline should the controller (or repeater) sending the
signal be one that senses collisions and automatically retransmits. ACT
controllers, RR501s, Ocelots, some coupler/repeaters and others
automatically resend after collisions.

For The Alien,

Insteon only responds to commands sent from devices that have been
"enrolled" in the system. You need physical control of a device to enroll
it. Each device has a "unique" ID. Commands include the ID of the sender and
target receiver.
