I have two roku devices. I ran the ipad remote app and picked one. I can't find any way to change now so that I control the other app. I tried killing the ipad app, but it still comes up and automatically connects to just one of my devices.
Re: How can you change your ipad controller device?
Just checked the app on my iPhone. Go to Settings, and right below where it shows which device you are connected to is a link that says "Switch Roku Device". Touch that and you will get a list of the devices on your network. I noticed it shows every device I have registered to me, even the ones not currently connected to the network, but those are grayed out and cannot be selected.
Dan Roku Stick (3600), Ultra (4640), Premiere (3920), Insignia 720p Roku TV, Sharp 4K Roku TV, Nvidia Shield, Windows 10 Pro x64 running Serviio and Plex on a wired Gigabit network.
