A few years ago I purchased the Roku Express and to this day everything is working just fine. I have recently purchased an Amazon Echo dot 3rd generation. Then I have purchased a new Roku Express that works with Alexa. What I have found is that both the old Express remote and the new Express remote control both devices. Does anybody know how I can change this issue and make it to where the remotes only work with the devices they came with?
You can not with IR remotes included with express, sorry. If neither is a 3700 express, you can buy wifi remote for each and pair them to each, and abandon the IR remotes completely. Wifi remote will ionly work on express 3900 & 3930 or newer.
