Because I only have one source component and the remote for that component can control my receiver's volume via CEC, the only thing I strictly speaking need the Harmony for is power the system on and off, unless I need to change the sound mode or deal with yet another stupid error message from my television that I don't care about. I can fire off the power-up and power-down macros via the Hub with voice commands via either Alexa or Google Assistant, so I really don't need to futz with the actual Harmony remote much at all.
