I think there is one important point. X-10 lamp & appliance modules are dirt
cheap. A lot of people would like to be able to continue using them while
slowly phasing in a more robust system. UPB doesn't allow that so its "all
or nothing" unless you want two different control systems.
X-10 also has wireless controls which are, so far, missing from UPB. I get
around with difficulty, leaning on a crutch or walker. With a few exceptions
(kitchen sink, bathrooms) I haven't touched a wall switch in years,
controlling nearly everything wirelessly.
If I were in your shoes, building anew, the one question I would like
answered is how UPB distinguishes the UPB "pulse" from similarly shaped
40-50V triac noise pulses? Perhaps there's enough difference in the
frequency content of the UPB "pulse" vs. other noise pulses but I'm dubious.
Also, I think it's a risky strategy to use a noise pulse as a data element.
While I recognize that one person's "noise" is another's rock'n'roll, when
everyone else in the world is trying to filter out things that look like
this I wonder how long it will be before we'll be reading about UPB signal
suckers.
