source lgtv-venv/bin/activate
pip install git+https://github.com/klattimer/LGWebOSRemote

To install it system wide:

sudo python -m venv /opt/lgtv-venv
source /opt/lgtv-venv/bin/activate
sudo pip install git+https://github.com/klattimer/LGWebOSRemote

Example usage

# Scan/Authenticate
$ lgtv scan
{
    "count": 1,
    "list": [
        {
            "address": "192.168.1.31",
            "model": "UF830V",
            "uuid": "10f34f86-0664-f223-4b8f-d16a772d9baf"
        }
    ],
    "result": "ok"
}
$ lgtv auth 192.168.1.31 MyTV
# At this point the TV will request pairing, follow the instructions on screen

# Commands are basically
#$ lgtv TVNAME COMMAND COMMAND ARGS

$ lgtv MyTV on
$ lgtv MyTV off

# If you have the youtube plugin
$ lgtv MyTV openYoutubeURL https://www.youtube.com/watch?v=dQw4w9WgXcQ

# Otherwise, this works reasonably well
$ lgtv MyTV openBrowserAt https://www.youtube.com/tv#/watch?v=dQw4w9WgXcQ

Caveats

You need to auth with the TV before being able to use the on command as it requires the mac address.

TODO

Implement the following features:

closeToast
createAlert
closeAlert
getSystemSettings

Bugs

I couldn't test youtube because it seems the app isn't installed and not available to download right now maybe they're updating it?
