Hi @lo414
Welcome to the Roku Community.
We would like to know how we can help. May I know what type of remote you are using right now?
It seems like you're using one remote with more than one device; we suggest that you buy a new remote instead of using one remote with two devices. As of the moment, you can download the Roku mobile app to use as your remote with your other device.
We hope that this can be helpful.
Best Regards,
Arvy
