[WORKAROUND] LG TV Remote

Configuration

Sure. This is what I did. And it works for pre-WebOS models.
Particular script I use is for models released in 2011. Also have script for 2012 models.

In configuration.yaml add

script.powerofftv:
hidden: true
script.powerontv:
hidden: true

In the tv.py add your pairing key and your good to go. Of course restart HASS

This is the tv.py script.

Until someone works the script into a component I’ll keep using this and add shell commands for volume , channel changing, etc.

Turning TV on and off via HASS was what I needed.
