I really appreciate your reply. I am disappointed, but at least now I know. I could have sworn I had found a table of commands and the appropriate signaling (rising edges and such) somewhere, but it had been a long day and I can't find it again.
I have had two Harmony remotes, the first one was decent (except for when a device got out of sync), the second one ditched too many physical buttons and I couldn't deal.
I've been having some luck with smart come controls. Apps also seem to be pretty commonplace now. I just wish for something as programmable and versatile as a smart home (Google, Alexa, App) that also has a good (like /really/ good) button layout.
Otto Pylot, I seem to be running in to you everywhere.
