I FINALLY got to speak ear-to-ear with a guy who knew what he was talking about.....Here's the scoop, and it's not good.....
1. The IR "fall back" function is an attempted band-aid to a known bug that Harmony has with IP control. Rather than fixing this bug that is associated with the Harmony Elite (HE) buffering with Wifi (which causes the user to have to press a button multiple times to get a response), they implemented this IR fall-back feature.
2. OK, new info. I can pair my native remotes using IR only and each will control only the Ultra it is intended to control. But for some reason when the Harmony uses the fall-back, it does not ALWAYS limit itself to just the IR signal that is paired with the unit it is trying to control. It seems to SOMETIMES use other IR signals as well.....Which in my mind is another bug within the band-aid.
As a test, I did the electrical tape solution and sure enough it completely solved the multiple units responding issue, but this buffering problem that the Harmony guy said would occur, absolutely did....unacceptably so....I would say that on at least 25% of my button pushes I would have to repeat it multiple times to get it to work. This is a much worse situation that the occasional "should not respond" issue.
The Harmony guy predicted I would feel this way and said that my real options at this point are:
a) They fix the problem with the IP over WIFI problems. How long will this take? He is looking it to it and will call back tomorrow with an update.
b) I just live with the problem (whichever one I prefer)
c) I get a new remote. He gave me the names of their major high end competitors (URC/Savant/Control 4). I called two of them today and they do not have a solution that would work. Note that I am not able to run wires from a hub to my units.
I am really blown away that this may not be a fixable problem (at least not without construction or accepting exposed wires).
