I have 2 rooms - home theater room and master bedroom that need control.
bedroom has LG-Oled, Yamaha receiver and Apple TV4k and cable box. All but the cable box are wired Ethernet. Do I need anything more than an io extender in the bedroom to gain control? Reluctant to buy a second EA unit as I will likely never use the osd. If an extender will do it - which one is recommended. Thanks in advance.
