Hi, I have an HC300 installed in 2010 running 2.1.1 controlled by an SR250 remote for my home theater room. It is supposed to control 6 dimmers, 2 switches, a JVC projector, Denon avr, Sony bluray player, AppleTV, and Xbox. The Apple TV and Xbox are more recent adds so not part of the initial configuration. I removed the HC300 from my rack and attempted to reconnect the IR but haven't been able to get it to work properly again. Also, the app on my phone hasn't been able to control the system for many years. Please contact me if interested in assessing my situation and resolving the issues.
