MQTT WebOS Service

For WebOS 6. Maybe it works for earlier or later versions...?

Setup tv

There are two options:

WebOS developer

You can use the default way, as a LG WebOS developer: https://webostv.developer.lge.com/develop/app-test/using-devmode-app/

Rooted TV

Or you can root your tv, and get some additional options:

So start with https://rootmy.tv
Enable the SSH server in the Homebrew Channel
Set up your dev environment with the ares-cli: https://www.webosbrew.org/pages/configuring-sdk.html

Connect TV

Then you can connect with your tv:

ares-setup-device

Install app and service

Check out the code
Update these fields:

const host = 'YOUR MQTT BROKER HOST';
const port = '1883'; // OR THE POR OF THE BROKER
const username = 'YOUR MQTT USERNAME';
const password = 'YOUR MQTT PASSWORD';

Run the following commands:

ares-package tv-app/ tv-service/
ares-install ./com.slg.tv_0.0.1_all.ipk

The service and app are now installed.

Starting the service

The app is now installed on the home screen, and can be started from there.

If you've rooted your tv, you can also use a script to start the service automatically when starting the tv.

Copy the start_tv_service-file to /var/lib/webosbrew/init.d and make it executable:

chmod +x start_tv_service

After that, the service should start automatically.

Using the service

In Home Assistant, add two new sensors:

sensor:
  - platform: mqtt
    name: "LG TV PlayState"
    state_topic: "tv-service/playState"
  - platform: mqtt
    name: "LG TV AppId"
    state_topic: "tv-service/appId"

Now you can make an automation to listen to these states and turn lights on or off, or whatever you want to do...

TODO

Use the app to configure the service via the tv
Send a screenshot/some color information to color lights when pausing
