I am trying to just use my ROKU TV remote. I went through the set up steps to pair it to my cable box. Turn everything off. Connect the HDMI cable. Turn in my ROKU TV. Turn on my cable box with cable remote. Select the input. Press Enter.
but it won’t pair!!!! Very frustrated as I need this simple for my elderly aunt.
Perhaps a better alternative would be to use a "Universal Remote". I personally use an RCA Model RCRN04GR remote, and it controls an Arris cable box, my Sharp/Roku TV for starters. That may be all you need for your own applications. In my application, it ALSO controls a Pioneer Receiver, a Sony DVD player, and a Magnavox DVD/VCR Recorder.
It may present Too Many buttons for your aunt, but, all I can say is I'm elderly, and it works for me, and my wife is elderly, and it works for her because she knows which buttons turn the TV on and off and change channels on the cable box and control volume and mute. And for her, that is sufficient.
