I have 2 Roku's within my home. I want to be able to control all from my phone on the Roku app. I have 1 set up but when it searches for other remote devices it doesn't find the 2nd one.
Are you're Roku devices linked to the same Roku account? If you're not sure, check the email address displayed under Settings->System->About. The devices and the phone must also be connected to the same network.
