This is Go library and a terminal application for remote control of LG WebOS smart televisions. Works on Linux and Windows and probably on OS X as well. It has been tested with LG 42LB650V-ZN television.

Download pre-built executable binary for your OS/architecture from: https://github.com/snabb/webostv/releases

Run the downloaded application in a terminal window. On Linux, add execute permissions after downloading (chmod 755 webostvremote-linux-amd64). The IP address or name of the TV can be given as a command line argument:

./webostvremote 192.0.2.123

If the address is not supplied, it will try to connect to the default address LGsmartTV.lan.

Install Go compiler if you do not have it:

curl https://dl.google.com/go/go1.12.linux-amd64.tar.gz | sudo tar xzC /usr/local
PATH=$PATH:/usr/local/go/bin

(See https://golang.org/dl/ for newer version and more detailed instructions.)

Compile:

git clone https://github.com/snabb/webostv.git
cd webostv
go build ./cmd/webostvremote

The compiled binary webostvremote is produced in the current working directory. If there are errors, try again with up-to-date Go compiler version.

package main

import "github.com/snabb/webostv"

func main() {
	tv, err := webostv.DefaultDialer.Dial("LGsmartTV.lan")
	if err != nil {
		panic(err)
	}
	defer tv.Close()
	go tv.MessageHandler()

	_, err = tv.Register("")
	if err != nil {
		panic(err)
	}

	err = tv.SystemTurnOff()
	if err != nil {
		panic(err)
	}
