There are roku commands that when a roku sees them issues hdmi-cec signal over the hdmi cable and controls the tv the roku is connected to, no use of the tv IR pickup sensor. But only one roku remote ever had those commands preset and that was the Onn Roku Soundbar IR remote, very rare to find. But there are universal remotes that have access to these commands via use of advanced code or EFC's that 5 digit codes for individual commands. Your roku HAS to be able to accept IR commands this won't work with roku stick!! The universal remotes are the Inteset 422-3 and One-For-All urc-7880. Each has roku code 03061 on board that accepts these efc's, the commands are Tv power- 00147, volume up- 00134, volume down- 00136, and mute- 00140. to map these commands to universal remote:
1. roku device with setup code 03061
2. press and hold set?magic for two blinks, release
3. enter 9 9 4
4. tap set/magic for one blink
5. enter 5 digit efc
6. pick a key
