Whenever I push the button, a playlist will start for 30 seconds. Afterwards I want it to switch back to the sonos radio that we always listen to.

I was wondering if there is a possibility to switch (back) to sonos radio after a certain amount of time.

Or is there any work around?

thanks

What is it?
Hub TCP server for using the IR module via HTTP.
Both to record of new signals with a given name and to play them back.
Using net since SDK doesn't have the nodejs HTTP-module available.

Why?
I really wanted to be able to call my IR module from my phone homescreen or Google Home (via IFTTT). I got it working so I wanted to share it if anyone else find it helpful 🙂

The code is what could be called a POC, so code feedback and/or changes are totally welcome.

How does it work?

Record a signal GET {ip}:1338?record={name_of_signal} Plays a signal GET {ip}:1338?cmd={name_of_signal} Cancel recording GET {ip}:1338?cancelRecord=true

Example;

call GET 192.168.0.100:1338?record=volume_up Press Volume Up on remote towards IR module returns 200 OK Signal volume_up stored! call GET 192.168.0.100:1338?cmd=volume_up returns 200 OK Signal sent! Volume goes up 🙂

The code

module.json

{ "name": "IRTCP", "version": "1.0.0" }

main.js

// main.js const net = require("net"); const ir = require("ir"); const datastore = require("datastore"); const utils = require("./utils"); const respondToClient = function(c, statusCode, message) { c.write( "HTTP/1.1 " + statusCode + "\r\n" + "\r\n" ); c.write(message); c.end(); } const handleCmd = function(c, cmd) { datastore.get(cmd, function(err, strBuffer) { if (!err && strBuffer) { var signal = new Uint32Array(utils.str2ab(strBuffer)); if (!ArrayBuffer.isView(signal)) { return respondToClient(c, "422 Unprocessable Entity", "Unknown signal"); } ir.play(signal, function(err) { if (!err) { return respondToClient(c, "200 OK", "Signal sent"); } return respondToClient(c, "500 Internal Server Error", "Couldn't send signal"); }); } else { return respondToClient(c, "422 Unprocessable Entity", "Unknown cmd"); } }); } const handleRecord = function(c, name) { /* TODO: add a timeout for listening for complete */ ir.record(); console.log("recording signal..."); ir.on("recordComplete", function(signal) { datastore.put(name, utils.ab2str(signal.buffer), function(err) { if (!err) { console.log("Signal " + name + " stored!"); return respondToClient(c, "200 OK", "Signal " + name + " stored!"); } else { return respondToClient(c, "500 Internal Server Error", "Couldn't store signal"); } }); }); } var server = net.createServer(function(c) { console.log('server connected'); c.on('end', function() { console.log('server disconnected'); }); c.on('data', function(data) { console.log(data); var match = data.toString().match(/GET \/\?.[^ ]*/); if (!match) { return respondToClient(c, "403 Forbidden", "Forbidden method"); } var params = utils.parseParams(match[0].split("GET /?")[1]); if (params.cmd) { return handleCmd(c, params.cmd); } else if (params.record && params.record.length > 0) { return handleRecord(c, params.record); } else if (params.cancelRecord) { ir.cancelRecord(); console.log("recording canceled!"); return respondToClient(c, "200 OK", "Recording canceled!"); } else { return respondToClient(c, "403 Forbidden", "Forbidden params"); } }); }); server.listen(1338, function() { console.log('server bound', server.address().port); });

utils.js

const ab2str = function(buf) { return String.fromCharCode.apply(null, new Uint16Array(buf)); } const str2ab = function(str) { var buf = new ArrayBuffer(str.length*2); var bufView = new Uint16Array(buf); for (var i=0, strLen=str.length; i < strLen; i++) { bufView[i] = str.charCodeAt(i); } return buf; } const parseParams = function (s) { var obj = {}; var arr = s.split("&"); var temp; for (i = 0; i < arr.length; i++) { temp = arr[i].split("="); obj[temp[0]] = temp[1]; } return obj; }; exports.ab2str = ab2str; exports.str2ab = str2ab; exports.parseParams = parseParams;

I have successfully implemented the SDK to create an OSC module that send a trigger to QLab. However, it only works once. In other words, I press the button, it send the OSC string to QLab, everything works as it should. But then it's as if it stops listening for another button press. Am I missing something? Here is my JS in main.js:

var oscClient = require("./osc").create("192.168.1.202", 53000); var buttonManager = require("buttons"); buttonManager.on("buttonDown", function(obj) { oscClient.send("/cue/2/start", function() { console.log("message sent"); }); });```

hubsdk.flic.io is currently down. Please fix this.
