We use an old RCA for our sound system and it works great for our needs. However the remote was lost years ago, and the only thing that works with it is this Logitech Harmony remote. I’ve successfully cloned the IR commands from the Logitech remote I need to control the RCA unit (Power toggle, Volume Up/Down, etc.) - but no matter what I do, I cannot get the RCA unit to accept commands from my flipper.

I tried putting the flipper on the RCA, near the IR sensor while cloning and the RCA would do those actions during the cloning process, so I know the commands are being sent and received. But when I try those commands from my Flipper, the RCA unit does nothing. I’m at my wits end here.. what can I do differently to get the RCA to accept commands from the Flipper??
