Harman/Kardon Hup App Simple API and Demo

API and demo to work with Harman-Kardon Web Hub App

Install

npm install harman-kardon-hubapp-api

Usage

The library provides functions to generate RESTful API endpoints. Some values set below were specific to the hackathon event from which this library was built; you will need to get these values (see the demo video referenced in the Description below).

var hk = require('harman-kardon-hubapp-api');
var request = require('request');

var hub = {                              // Harman/Kardon Hub Variables
  "SessionID":"1000",                    // Default value of the SessionID
  "DeviceID":"2586126661808",            // This was the DeviceID of the device we used at our Hackathon
  "PersistentID":"7180490900718530992",  // This was the PersistentID of the first song in our media list 
  "baseUrl":'http://10.0.1.9:8080/'      // This was the URL assigned when opening the Hub app on our iPhone
};

request(hk.initCmd(hub), function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
    hub.SessionID = JSON.parse(body).SessionID;   // resets the SessionID based on initialization call
  }
  
  // ... continue with other RESTful API calls ...
}

Description

This api and demo was built for an ATT Hackathon in San Diego in October 2015. One of the vendors participating in the demo was Harman/Kardon. Harman/Kardon provided wi-fi enabled speakers (specifically the Omni10) to hackers to see what kinds of cool things could be accomplished using their APIs and SDKs. There was a RESTful API accessible via the HKWebHubApp, as well as Android and iOS APIs. My team chose to utilize the HKWebHub App for "quick-and-dirty" hacking. We recommend going this route to get started, because it took us less than an hour to get it working initially. (Note: As of this writing, you must have an iOS device to use the HKWebHubApp).

Demos

You will need to tinker with a few parameters and setting to get these demos set up for your needs. They are mostly just here to give you an idea of how to use the library.

Sensors Demo

This demo was built to modify the song being played and adjust the volume dependent on sensor inputs posted to a server. You should be able to run it with liveDemo=false. It demonstrates many of the things you would need to do to get up and running.

node runDemo.js

Volume Control Demo

This demo was built when debugging how to use the volume control REST-ful API calls

node test_volume_control.js

Troubleshooting tips

If you run into problems, console.log the commands that the library is generating and try running them from a curl statement or from the browser. It helped me find typos and peculiarities of the interface. Here's an example:

console.log(hk.setVolumeCmd(hub,vol));
