Amazon Dash Doorbell

So, my weekend hack project came to me in the form of a tweet. Thanks to Christian Hambly for the idea:

Myself and my eldest set about installing Node, developing the required code mainly based upon the original article, and working with Pushover which I have already used previously for notifications, the final code looks as follows:

function send_pushover_notification() {

  var push = require( 'pushover-notifications' );

  var p = new push( {
      user: "xxxx",
      token: "xxxx"

  var msg = {
      message: "Somebody is at the door!",
      title: "Doorbell",
      sound: 'pushover',
      priority: 1

  p.send( msg, function( err, result ) {
      if ( err ) {
          return false;

      if(result.status == 1) {
        return true;

  return false;

var dash_button = require('node-dash-button'),
    dash = dash_button('xx:xx:xx:xx:xx:xx'),
    exec = require('child_process').exec;

dash.on('detected', function() {
    console.log('Button pushed!');



We have a server fitted in the loft which I installed Node onto, then installed PM2 in order to run the application as a service.

The eldest installed Pushover on his iPod Touch which means he knows exactly when the doorbell rings!

The final result:


Also worth considering when it comes out in the UK Amazon IOT Button
