I hung up three TVs on one wall in my office so I could watch multiple sports games. All three are Roku TV (one TCL and two Hisense). I purchased these specially for Roku and the use of the wifi remote so there would be no remote interference.
I bought three wifi remotes and paired to each TV. They work great for about a day or two but after a while one remote will control all tvs. It is very annoying to have to re-pair these remotes every two days.
So you have 6 roku remotes? the IR remotes that came with the tv's and wifi remotes you bought separately? I'm just wondering if you're getting the IR remotes mixed in with wifi remotes and causing you problems? I have had many wifi remotes, the only time my roku tv's stop working with wifi is when I paired too many remotes to roku tv and it forgets all of them, having just one wifi I have never lost programming.
I have no idea what it does, but there's a "Disable Auto-Pairing" option buried in the "Platform Secret Screen". You get to it by pressing Home 5 times followed by FF (>>), Play/Pause/ Rewind (>>), Play/Pause, FF. Once there, go to the "RF Remote Menu" and then the "Pairing Menu". You may have to break out an IR remote to re-enable it if it causes your RF remote to no longer pair.
