Hi All

With lots of help from people here and Liam Gladdy's brilliant original decoding of the Sky protocols, I've got working control going of Sky HD+ and apparently SkyQ uses the same setup.

It's pretty straightforward - I create an Activity Script which connects to the Sky box

var IPAddress="";
var Port=49160;
var Timeout=100;
var str = "";
var receivedText = "";
var len;
var command="";

function ConnecttoSky()
socket = new TCPSocket(false);
socket.onConnect = onConnect;
socket.onData = onData;
socket.onClose = onClose;
socket.onIOError = onIOError;
socket.connect(IPAddress, Port, Timeout);

Then the only callback we really need is OnData

function onData(){
var code;
var writeText;

// System.print("Ondata.");
receivedText =;

if (receivedText.length < 24){
len = 1;
else {
//System.print("Writing Data");
code = SkyRemoteCommands[command];
// System.print ("Hex is " + showHEX(String.fromCharCode(code & 0xff)));
writeText = "\x04\x01\x00\x00\x00\x00"+chr[Math.floor(224 + (code/16))]+chr[code % 16];
socket.write (writeText);
writeText = "\x04\x00\x00\x00\x00\x00"+chr[Math.floor(224 + (code/16))]+chr[code % 16];
socket.write (writeText);

// socket.write (ArrayToString([0x04,0x01,0x00,0x00,0x00,0x00,Math.floor(224 + (code/16)),code % 16]));
// socket.write (ArrayToString([0x04,0x00,0x00,0x00,0x00,0x00,Math.floor(224 + (code/16)),code % 16]));



and this uses two fixed arrays

ar SkyRemoteCommands = new Array()

SkyRemoteCommands = {

var chr=new Array()

"\xF0", "\xF1", "\xF2", "\xF3", "\xF4", "\xF5", "\xF6", "\xF7", "\xF8", "\xF9", "\xFA", "\xFB", "\xFC", "\xFD", "\xFE", "\xFF"]

Then, when I want to use one, I just set the global variable command, and then call ConnectToSky()


That's it - really simple and very reliable.
