Question: Possible to retrieve input 'name' as seen by the TV?
Hello - this is more of a feature/capability question. First off - much thanks for your help and support in building and maintaining this plugin. 

I previously had devices directly wired to the LG TV HDMI inputs; this made it super easy to do automations based on what device was being used (or "activity", in Harmony parlance). LG TV lets you 'name' the inputs; I'm guessing there is some sort of HDMI fingerprint it remembers and displays that name of the device on the screen when you cycle through HDMI inputs. 

I recently added an AV Receiver to my setup and now have all my devices wired through the AVR. This makes automating based on the HDMI input port no longer possible. However, interestingly, the LG TV seems to be able to "see" the fingerprint of the device still; maybe the AVR is passing it through somehow. Depending on what signal I have my AVR displaying, the TV can see that I have a "PS4" or an "Apple TV" device on, which are the names I gave these devices when they were directly connected to the TV. I'm wondering if there is a way I can query for the value of this "name" in a Homekit shortcut/automation? This would allow me to do X or Y based on the current device in use w/ the TV.
