If I were to buy two roku express 4K+ to use in the same room where there is two TVs. Will one remote work with both roku units or are they unique enough where you can use them individually without problems.
I need to verify that one remote will not trigger both units.
The Express 4k+ comes with the voice remote that works via Wi-Fi direct. The remote can only be paired to one Roku device at at time, so you won't have any problem with one remote controlling two devices.
To expand on @renojim 's reply ...
Each wifi-direct remote will pair to and control one Roku unit only. So you'll have a separate remote to control each Roku. The remotes look identical though, so you'll probably need to label them in some way to avoid confusion.
