NPM version npm Build Status XO code style License

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

this is a fork of lgtv2, updated to fix some issues.

Installation

npm install lgtv2

TV configuration

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

Usage Examples

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();
    });
    
});

API

options
  • 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
methods
request(url [, payload] [, callback])

Payload and callback params are optional.

subscribe(url, callback)
disconnect()

Closes the connection to the TV and stops auto-reconnection.

getSocket(url, callback)

Get specialized socket connection for mouse and button events

Example:

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

is called when TV prompts for App authorization

connect

is called when a connection is established and authorized

connecting

is called when trying to connect to the TV

close
error

is called when Websocket connection errors occur. Subsequent equal errors will only be emitted once (So your log isn't flooded with EHOSTUNREACH errors if your TV is off)
