I didn't see any of the remotes, but I don't have the video plugin activated on this machine.
I agree that it is helpful to list the motion sensors, to be able to see where a command is coming from, and what HC/UC are in use (although if you have a macro on one of those codes, it will be listed in the "find other computers" screen).
As I suggested earlier, you can monitor the status of the Powerflash with a simple "dummy" appliance module (a one-way, not a two-way), set to the same HC/UC as the Powerflash. Call it "PowerFlash" if you want. When those codes come in, it should turn on and off (on screen), and you'll see it listed as a receive code in the Activity Monitor.
However, whatever you are triggering with that HC/UC will also be listed, so adding the appliance module might be overkill. That's you to decide.
One other thing (and it is listed in the Bug List - see my signature for the link): Currently, the SDK will "translate" outgoing old-fashioned "on" commands into "Extended Dim" commands for lights which are defined in AHP as SoftStart capable modules. I ran into this myself. I was using AHCMD to send something like "C5 On", and it was actually sending "C5 ExtCode 31 3f" (Which is the Extended Dim version of "turn on at 100% immediately - without SoftStart). When I changed the module definition in AHP to an "old" style lamp, it started sending the correct "On" command (as I recall, at least).
