I have a sharp roku tv. I want to add a roku ultra to the tv. How will the remotes work? Will one control both devices or will I still need to use both? If one will work, how will I know which unit is being controlled?
No, there will not be conflicts between the remote either using IR or Wifi. Both home screens could be mistook for the other if you use the same theme, just use different Themes.
The ultra remote can be programmed to control the sharp tv power and volume. And if its 2019 ultra, mute command as well.
