Simple Node.js module to remote control LG WebOS smart TVs.

this is a fork of LGTV.js, heavily modified and rewritten to suite my needs.

With v1.4.0 the location and filename of the keyFile is changed, so you likely will have to accept the connection on your TV again after upgrading to 1.4.0.

• node-red-contrib-lgtv - Node-RED Nodes to control LG webOS Smart TVs.
• lgtv2mqtt - Interface between LG WebOS Smart TVs and MQTT.
• homebridge-webos-tv - Homebridge plugin for LG WebOS TVs.
• ioBroker.lgtv - LG WebOS SmartTV adapter for ioBroker.

npm install lgtv2

You need to allow "LG Connect Apps" on your TV - see http://www.lg.com/uk/support/product-help/CT00008334-1437131798537-others

Subscribe to volume and mute changes and output to console:

var lgtv = require("lgtv2")({
    url: 'ws://lgwebostv:3000'
});

lgtv.on('error', function (err) {
    console.log(err);
});

lgtv.on('connect', function () {
    console.log('connected');
    
    lgtv.subscribe('ssap://audio/getVolume', function (err, res) {
        if (res.changed.indexOf('volume') !== -1) console.log('volume changed', res.volume);
        if (res.changed.indexOf('muted') !== -1) console.log('mute changed', res.muted);
    });
    
});

Turn TV off:

var lgtv = require("lgtv2")({
    url: 'ws://lgwebostv:3000'
});

lgtv.on('error', function (err) {
    console.log(err);
});

lgtv.on('connect', function () {
    console.log('connected');
    lgtv.request('ssap://system/turnOff', function (err, res) {
        lgtv.disconnect();
    });
    
});

• url - websocket url of TV. default: 'ws://lgwebostv:3000'
• timeout - request timeout in milliseconds, default: 15000
• reconnect - reconnect interval in milliseconds, default: 5000
• keyFile - path for key storage. Will be suffixed with hostname/ip of TV. default: Linux: ~/.lgtv2/keyfile-, macOS: ~/Library/Preferences/lgtv2/keyfile-
• saveKey - you can override this with your own function for saving the key
• clientKey - you have to supply the key here if you're using a custom saveKey method

lgtv.getSocket(
    'ssap://com.webos.service.networkinput/getPointerInputSocket',
    function(err, sock) {
        if (!err) {
            sock.send('click');
        }
    }
);
