mechhome

A framework for DIY home automation and security monitoring in node.js

MechHome for node.js

This project provides a framework for DIY home automation and security monitoring.

npm install mechhome

MechHome currently relies on a Redis backend, meaning you must first install Redis.

config/mechhome.properties supplies parameters for the application and all plugins.

The application won't do a whole lot without plugins defined: mechhome.plugins = plugin name 1,...,plugin name N

Plugins are implemented by creating a plugins/plugin_name/index.js file with the following at a minimum:

function init(appHandle) { appHandle.register('plugin name', function(type, obj) { // Handle application events here }); exports.init = init;

The appHandle currently provides access to the following:

  • register('plugin name', callback) - This allows the plugin to receive event data
  • log('type', object) - Messaging to other plugins (rename might be in order)
  • config['key'] - Access to properties file
  • setZone(oldZone, newZone) - Modify a zone (see database.js:initialize() for example definition)

See some of the existing plugins for more examples.

This project is in early development, and any feedback/changes are appreciated.

  • UX/UI work for the web_interface plugin - I'm not a web developer and it shows...
  • Implement proxy plugin to allow MechHome processes on other machines to forward device data, etc.
  • Add implementation details (and Arduino code) for the arduino_device plugin (dcrouse)
  • Create 'device' plugins for system alerts, HVAC (e.g. Nest), lighting control, X11, etc.
  • Evolve the concept of zone types, with different behavior for doors vs. motion sensors, for example. Should types be plugins?
  • Create non-persistent 'database' plugin alternative to the current Redis-backed database.js.
  • Improve the way zones are defined (i.e. not hard-coded in database.js:initialize())
  • Finish demo plugin
  • Write some tests!
  • Lots more...
