Samsung TV Control can't select HDMI1/HDMI2 etc

[marklynch]

The problem

I am trying to control a samsung TV and be able to switch reliably between the sources.

When I call the media_player.source with hdmi1 it gives the following error.

Entity media_player.samsung_cu8000_43_tv_2 does not support source HDMI1

The full keycodes list on the documentation page only lists:

KEY_TV
KEY_HDMI

However, the source for this lists additional sources: https://github.com/kdschlosser/samsungctl

KEY_TV
KEY_HDMI1
KEY_HDMI2
KEY_HDMI3
KEY_HDMI4

It would be great if these additional sources could be added - happy to have a try adding these if can provide a steer in the right direction.

I had a bit of a further dig into the code and added some additional sources here as follows:

core/homeassistant/components/samsungtv/media_player.py

Line 43 in a102eaf

SOURCES = {"TV": "KEY_TV", "HDMI": "KEY_HDMI"}

Updated to:

SOURCES = {"TV": "KEY_TV", "HDMI": "KEY_HDMI", "HDMI 1": "KEY_HDMI1", "HDMI 2": "KEY_HDMI2"}

This makes it appear in the media player menu - but doesn't appear to do anything on the TV ☹

I've been playing around with https://github.com/kdschlosser/samsungctl to see if I can get that working in order to confirm if this should work. Will continue looking.

I really hope this gets figured out. This is my only problem with this.
