A:
My Harmony controls an LG OLED 4K TV, Xfinity cable box, Apple TV, Yamaha A/V receiver and Panasonic DVR seamlessly. It really does replace five remotes. I managed to accidentally crushed one, bought another, and Logitech had all the settings saved, so they programmed the new remote over the Internet. When I ruined the first, it was really cumbersome to handle three remotes ( TV, receiver, and cable) again.
