Thanks Bobby for your great insights and elaboration regarding X-10.

At one time quite a few years ago, long before fluorescent lighting and
other issues degraded my X-10 system, I had a very workable arrangement
here, and used it without complaints for perhaps 2 decades or longer.

Over the course of the last few years, I have moved a lot of my branch
circuits over to a transfer panel for a standby generator, removed the
phase couplers and amplifiers and some filters I had added, and
essentially removed most of my X-10 components except those within very
close proximity to one another.

I have no doubts whatsoever that proper filters, additional amplifiers,
careful removal of the worst offending noise sources, etc. could tame my
system. I just no longer have an interest in doing any of this, and I do
have many hard-wired Ethernet devices doing the specific things I need
to do with little or no problems.

I've had commercial and ham FCC licenses since the 1950s, and have built
35 Heathkits in total, as well as spent most of my professional career
as an electrical / electronics engineer, so the technical aspects are
comfortable and familiar. I attended classes with Irv Reed, who (quite
famously) co-developed the Reed Solomon coding methods (at MIT / Lincoln
Labs) still used prominently to mitigate bit errors in communication
channels, and still feel up to the task of analyzing and designing such
things. In the case of my own X-10 EMI as well as the more troublesome
wideband EMI that compromises my shortwave and AM reception, I have
learned to live with it. Even if I am willing to invest the time and
effort and money, my neighbors still create a lot of powerline and near
DC to 20 MHz trash as well.

I entirely agree that Zigbee has been far too long in coming although
there are some devices out there. Hardly a replacement for X-10 at this
point. And Insteon appears to have gained enough traction and solved
enough problems to be the real contender at this stage.
