Imagine you could control other devices with a simple JavaScript API, right from your browser.

control_devices.dreamcode.js

// Ask the coffee machine at IP 192.168.2.2 to do its job
device('192.168.2.2')
.do( 'coffee' )
.then( wakeMeUpCallback )

// turn all lights on
device.findAll('light').do('turnOn')

Checkout http://ninjablocks.com/ it's running Node and exposes webhooks to it's connected devices. Right now, you could definitely make it turn on your coffee machine, though it's probably going to need some arduino smarts to notify you when it's done. Just set your alarm for 5mins after the coffee is scheduled :P

For example, here's the temperature data (in Celsius) for my house recently:

{
  "result": 1,
  "error": null,
  "id": 0,
  "data": [{
    "t": "2013-05-06T12:00:00.000Z",
    "v": 22.077272727272728
  }, {
    "t": "2013-05-06T13:00:00.000Z",
    "v": 21.83124999999998
  }, {
    "t": "2013-05-06T14:00:00.000Z",
    "v": 21.767647058823524
  }, {
    "t": "2013-05-06T15:00:00.000Z",
    "v": 21.656521739130405
  }, {
    "t": "2013-05-06T16:00:00.000Z",
    "v": 21.374193548387094
  }, {
    "t": "2013-05-06T17:00:00.000Z",
    "v": 20.998823529411773
  }, {
    "t": "2013-05-06T18:00:00.000Z",
    "v": 20.626666666666683
  }, {
    "t": "2013-05-06T19:00:00.000Z",
    "v": 20.431168831168836
  }, {
    "t": "2013-05-06T20:00:00.000Z",
    "v": 20.22666666666667
...

Typo police: "to do it's job" should be "to do its job".

@EvanHahn fixed, cheers!

@jpillora

this is awesome! I want an API for all the things in my house! Let's make some dream code for that, would make a cool example

More typo police: "it's connected devices" should be "its connected devices".

"it's connected devices" == "it is connected devices"
