Not sure, I did go through all know APIs and the app itself, and I don’t think there is something especially useful not already discovered in an API. A way to switch between HDMI devices, that would be awesome.
I am super happy to get PRs. But I am unsure if this fits into this media component.
Actually there is an Ambilight component Philips Android TV Ambilights (Light) component
Check that out, it supports a lot of different modes. Maybe your change is already built in or it fits better there.
Ideally we should built a python module for the Philips TV. It should support everything from media player, app switching and amiblight stuff, so everything the API supports.
This python module should then be used for both Ambilight and media player.
