Apologies in advance - if it wasn't for water I wouldn't retain anything. So new install seems to have gone well. HR54 and C61K all for one TV (don't start). Reprogrammed the HarmonyOne and all is good except for the issue of both boxes turning on simultaneously. I previously had 2 HR24s stacked on top of one another and I did something 6 years ago when I got them so that the H1 recognized each box as having its own unique On/Off. When I pointed the remote at both and selected the appropriate Activity on the H1, only the corresponding box respond accordingly. I did something with the DTV remotes at the time setting in the 1/2 position as I programmed the H1. I think. Maybe learning each On/Off code? So I watched as the installer when thru the config for each new box and assigned the appropriate coded remote. How can I transpose this functionality to the H1? Can it be set so that each box is somehow identified to the H1 with its own unique On/Off functionality? As always, thx in advance.
