Ruby script to turn on a LGTV running WebOS 3, using "wake on LAN".

lgtv_turn_on.rb

#!/usr/bin/ruby
# Based on: https://gist.github.com/dgv/2865897 and https://gist.github.com/zunda/187139
# Idea from: https://github.com/efpe/amazon-alexa-lg-tv
# In order for this to work, first go to the TV "General" settings and turn on "Mobile TV On".

# Change this to the actual value.
# First find the TV IP, e.g. from your router's list of connected devices.
# Then run "arp -a" on a computer and you'll see the MAC by its IP.
# Maybe you need to "ssh <the ip>" before it will turn up in arp. Not sure.
TV_MAC_ADDRESS = "xx:xx:xx:xx:xx:xx"

require "socket"

def send_wake_on_lan_packet_to_mac_address(mac_address)
  addr = ['<broadcast>', 9]
  socket = UDPSocket.new
  socket.setsockopt(Socket::SOL_SOCKET, Socket::SO_BROADCAST, true)
  data = "\xFF".force_encoding(Encoding::ASCII_8BIT)*6 + [ mac_address.gsub( /:/, '' ) ].pack( 'H12' )*16
  puts("Wake-On-Lan packet sent to MAC address "+ mac_address)
  socket.send(data, 0, addr[0], addr[1])
end

Hello good afternoon!
How do I turn the TV off and send "click", "right", "left", ie remote control commands?
