So I looked all over for InHomeFre, without success.
There are a LOT of sites and forum posts where people recommend it, but they all link back to a few of Ken's websites, which no longer exist. Do you know of any places where this software is still available for download?
I did however have some success on another front. A number of sites that talked about InHomeFre noted that the "SmartHome Device Manager" software was required for InHomeFre to work. Searching for SDM, I found this website:
http://fredricksensoftware.us/Insteon/which has five different versions of it for download. I installed their recommended version, 235, and it detected my 2414U right away.
Luckily for me, the SDM software logs the activity on the power line! So here is a log, where I used the HR12A PalmPad remote and the RR501 transceiver to interact with a LM465 lamp module:

So it seems as though the RR501 is forwarding the RF commands out onto the power line
FOUR times, not the twice that I had originally thought.
So the HR12A sends SIX RF commands (as per Dave), which the RR501 hears and forwards to the power line as FOUR PL commands, which the lamp modules interpret as TWO commands?
Do "standard" powerline modules send and trap repeats of the signals for better reliability, like the RF controls do? (In other words, if I had one of the plug-in controllers with the buttons on it, and pressed "dim", would it only send it out on the power line once? Or would it send it multiple times quickly, just like the RF controllers do?)
