I have 2 hisense tvs 1 above the other. I have one of the rechargeable voice remotes. I paired it to one TV and a few days later it started controlling both volumes and voice controls everything on both tvs at the same time
Hisense Roku tv's? Point the voice pro at your cellphone camera, if you see flashes its emitting IR commands and so would control all tv's thst use the IR commands. It has to be paired to given Roku tv, then it would only control one roku tv at a time.
