pimatic

pimatic is a home automation framework that runs on node.js. It provides a common extensible platform for home control and automation tasks.

It defines several shemata for different home devices and sensors, so that all devices can be controled uniform and are presented in a common interface.

Automation tasks can be defined by rules in the form of "if this then that", where the "this" and the "that" part can be fully custimized by plugins. See the rules section for more details.

The mobile frontend plugin provieds a nice web frontend with a sensor overview, device control and rule definition. The web interface is built using express and jQuery Mobile.

Installation

First you need to install node.js that comes with the package manager npm. Then you can run

mkdir pimatic-app
npm install pimatic --prefix pimatic-app

to install the pimatic framework.

Configuration

I recommend to start with the default config:

cd pimatic-app
cp ./node_modules/pimatic/config_default.json ./config.json

The config is in the json format and currently includes five sections:

{ 
  "settings": { ... },
  "plugins": [ ... ],
  "devices": [ ... ],
  "rules": [ ... ]
}

The "settings"-section

The "settings"-section contains the configuration for the http- and https-server. You have to set "username" and "password" for the authentication or disable it. In the default config just the http-server is enabled and configurated to run on port 80.

See the config-shema for more details and all configuration options.

The "plugins"-section

In the "plugins"-section you have to list all plugins to load in the form of

{ 
  "plugin": "plugin-name" 
}

where "plugin-name" ist the name and directory of the plugin you want to load. All plugins are installed in the node_modules directory and prefixed with pimatic-.

Available Plugins:

The "devices"-section

The "devices"-section should contain all devices, you want to have registered in the framework. An actuator is typically provided by a plugin, so take a look at the desired plugin for more details about the configuration of your devices. A device configuration has the form

{ 
  "id": "light",
  "class": "SomeSwitch",
  "name": "Light in the kitchen",
  ...
}

where the "id" should be unique, the "name" should be human readable description and "class" determines the plugin and type of the device.

The "rules"-section

The "rules"-section can contain a list of rules in the form of:

{ 
  "id": "printerOff",
  "rule":  "if its 6pm then turn the printer off"
}

where "id" should be a unique string and rule a string of the form "if ... then ...".

Running

The server can be started with

cd pimatic-app/node_modules
sudo .bin/pimatic.js

To daemonize pimatic you can run:

cd pimatic-app/node_modules
sudo .bin/pimatic.js start

You can also use status, stop, restart.

###Install global

To make pimatic available global you can run:

cd ./node_modules/pimatic
sudo npm link

Then pimatic can be used with:

sudo pimatic.js [start|stop|status|restart]

Documentation

pimatics source files are annotated with literate programming style comments and docs. You can browse the self generated documentation with the source code side by side.

Extensions and Hacking

The framework is built to be extendable by plugins. If you have devices that are currently not supported please add a plugin for your devices. As well, if you have a nice Ideas for plugins or need support for specials actuators you are welcome to create a issue or submit a patch.

For plugin development take a look at the plugin template.
