This is the world of analog circuits and A/C power systems at its finest.
There are in fact boat loads of reasons why X10 does poorly over the A/C
network. The vast range of impedence mismatches is tremendous. So, the
signal is quenched in odd places and inconvenient times. The two way devices
make it possible for a control system to assert direct, and almost eventual
control over any device. But, is it 100% guarenteed? No, the wires can
break, an infinite impedence source can appear out of nowhere etc. This is no
different than any other control system. There are failure modes which render
control unobtainable.
You could put impedence matching devices at every port (automatic tuners of
sorts, like those used by Amateur Radio, on HF frequencies in particular).
All kinds of expensive and dramatically more difficult to install (separate
wiring) solutions are possible.
But, for the consumer it comes down to the 80-20 rule. If I can pay 20% of
the price and get 80% of the functionality, perhaps that is enough.
Not everyone is a perfectionist, and many people probably would not plug in
their coffee pot with an X-10 controller, especially if their system ever
failed to work reliably for them.
Don't get me wrong, I am not suggesting that all of this is perfect. But, it
is something that lets people play with home automation to wet their appetite
for real control. Which, after their X-10 experience will be weighted toward
dependability instead of toward affordability!
I have been sending pestering email messages to the folks at echelon about the
huge prices of lonworks starter kits and equipment. I told them that their
pricing is a great barrier to people trying to understand that technology. I
told them that they already have the network, and just need cost effective
equipment. I related the fact that the wireless crowd was going to quickly
overtake them if they did not get moving on price reductions. I told them
that a starter kit must be less than $400.00, which is about 1/4th the price
of the low end version they sell now. It might be good if others would push
on them to see if we can get a significan price break for equipment from this
solution space.
