Dreamscreen is one product that has pretty decent backlit TV capabilities. It now is using Wifi and in the future they will add some “Dream Connect” device but who knows when that will happen. For now you have to use the app on your phone to change HDMI input source and change other configurations.
I searched and didn’t really find anybody who did the integration with SmartThings however looks like it’s possible based on github and some python scripts running on a Raspberry Pi or similar:
Has anybody tried integrating this into a DTH? If not, I may give it a try using some of the work done already and maybe Flask to call out python scripts on a RASPI3 I got hanging around. Thoughts? Interest?
