My son has a Roku TCL TV as do I. They are both on the same network. We both occasionally use the Roku Mobile App to operate our TVs. You can access both TVs from the same app since they are on the same network. However, we often "accidentally" keep turn on each others TV (in the middle of the night sometimes!) just when trying to active the mobile app remote. In terms of technological solutions, how do I limit access to my Roku (its a TCL Roku TV) to just my Roku mobile app? Is it even possible?
