I have two Roku Express devices in my house. The first one is in my living room and the other is in my bedroom. The two televisions are on the same wall as both rooms are adjacent. When the TV in the living room is on regardless of cable or Roku being used and the TV in the bedroom is turned on when the Roku remote for the bedroom is used all of the sudden the TV in the living room switches to Roku. The original remote of the living room was chewed up by the dog and has been replaced with a voice activated remote purchased separately. Any ideas on how to stop this from happening?
If you can see both TVs from the same position, then the remote can see both of them and the one remote will control both Rokus. That's what happens with IR controls. You can't make one control only one device if the remote can see them both. If this is the case, then the Roku players need to be repositioned so that any one remote cannot see both players. IR can be tricky, as it's possible for it to reflect on mirrors or other smooth surfaces.
You could also try using the Roku app on a phone or tablet to control the Roku. This uses your WiFi network, not IR, and will absolutely only control the Roku you have selected.
One other thing to add to what @atc98092 said. You've discovered that the Voice Remote pairs to a Roku device, and controls only that Roku device. It's the IR remote (the Roku Simple Remote that came with the Roku Express) that can control multiple Roku devices if the Roku device can pick up the IR signal (either directly, or by bouncing off certain surfaces).
So, if repositioning things as @atc98092 suggesting isn't something that can be done (wall mountings, for instance) then getting another Voice Remote and pairing it may be your only solution. And you can find the $20 Voice Remote at Walmart, Best Buy, and other retailers, so you could have one today if you really wanted to do that.
