I have two Roku Hisense TVs pretty close to each other. The problem is if I were to hit the on button on a remote both TVs would turn on is there a way to stop this I have two remotes.
Only way is to abandon the IR remote that came with the tv's and buy two Wifi Voice remotes. Once a Wifi remote is paired to a Roku, or Roku tv it will only work with that one Roku device. It can't control both of them even you wanted to.
