+# Contributing to Home Assistant
+
+Everybody is invited and welcome to contribute to Home Assistant. There is a lot to do...if you are not a developer perhaps you would like to help with the documentation on [home-assistant.io](https://home-assistant.io/)? If you are a developer and have devices in your home which aren't working with Home Assistant yet, why not spent a couple of hours and help to integrate them? 
+
+The process is straight-forward.
+
+ - Fork the Home Assistant [git repository](https://github.com/balloob/home-assistant).
+ - Write the code for your device, notification service, sensor, or IoT thing.
+ - Check it with ``pylint`` and ``flake8``.
+ - Create a Pull Request against the [**dev**](https://github.com/balloob/home-assistant/tree/dev) branch of Home Assistant.
+
+Still interested? Then you should read the next sections and get more details. 
+
+## Adding support for a new device
+
+For help on building your component, please see the [developer documentation](https://home-assistant.io/developers/) on [home-assistant.io](https://home-assistant.io/).
+
+After you finish adding support for your device:
+
+ - Update the supported devices in the `README.md` file.
+ - Add any new dependencies to `requirements_all.txt`. There is no ordering right now, so just add it to the end.
+ - Update the `.coveragerc` file.
+ - Provide some documentation for [home-assistant.io](https://home-assistant.io/). The documentation is handled in a separate [git repository](https://github.com/balloob/home-assistant.io).
+ - Make sure all your code passes Pylint and flake8 (PEP8 and some more) validation. To generate reports, run `pylint homeassistant > pylint.txt` and `flake8 homeassistant --exclude bower_components,external > flake8.txt`.
+ - Create a Pull Request against the [**dev**](https://github.com/balloob/home-assistant/tree/dev) branch of Home Assistant.
+ - Check for comments and suggestions on your Pull Request and keep an eye on the [Travis output](https://travis-ci.org/balloob/home-assistant/).
+
+If you've added a component:
+
+ - Update the file [`home-assistant-icons.html`](https://github.com/balloob/home-assistant/blob/master/homeassistant/components/frontend/www_static/polymer/resources/home-assistant-icons.html) with an icon for your domain ([pick one from this list](https://www.polymer-project.org/1.0/components/core-elements/demo.html#core-icon)).
+ - Update the demo component with two states that it provides
+ - Add your component to home-assistant.conf.example
+
+Since you've updated `home-assistant-icons.html`, you've made changes to the frontend:
+
+ - Run `build_frontend`. This will build a new version of the frontend. Make sure you add the changed files `frontend.py` and `frontend.html` to the commit.
+
+### Setting states
+
+It is the responsibility of the component to maintain the states of the devices in your domain. Each device should be a single state and, if possible, a group should be provided that tracks the combined state of the devices.
+
+A state can have several attributes that will help the frontend in displaying your state:
+
+ - `friendly_name`: this name will be used as the name of the device
+ - `entity_picture`: this picture will be shown instead of the domain icon
+ - `unit_of_measurement`: this will be appended to the state in the interface
+ - `hidden`: This is a suggestion to the frontend on if the state should be hidden
+
+These attributes are defined in [homeassistant.components](https://github.com/balloob/home-assistant/blob/master/homeassistant/components/__init__.py#L25).
+
+### Proper Visibility Handling
+
+Generally, when creating a new entity for Home Assistant you will want it to be a class that inherits the [homeassistant.helpers.entity.Entity](https://github.com/balloob/home-assistant/blob/master/homeassistant/helpers/entity.py) class. If this is done, visibility will be handled for you. 
+You can set a suggestion for your entity's visibility by setting the hidden property by doing something similar to the following.
+
+```python
+self.hidden = True
+```
+
+This will SUGGEST that the active frontend hides the entity. This requires that the active frontend support hidden cards (the default frontend does) and that the value of hidden be included in your attributes dictionary (see above). The Entity abstract class will take care of this for you.
+
+Remember: The suggestion set by your component's code will always be overwritten by user settings in the configuration.yaml file. This is why you may set hidden to be False, but the property may remain True (or vice-versa).
+
+### Working on the frontend
+
+The frontend is composed of [Polymer](https://www.polymer-project.org) web-components and compiled into the file `frontend.html`. During development you do not want to work with the compiled version but with the seperate files. To have Home Assistant serve the seperate files, set `development=1` for the *http-component* in your config.
+
+When you are done with development and ready to commit your changes, run `build_frontend`, set `development=0` in your config and validate that everything still works.
+
+### Notes on PyLint and PEP8 validation
+
+In case a PyLint warning cannot be avoided, add a comment to disable the PyLint check for that line. This can be done using the format `# pylint: disable=YOUR-ERROR-NAME`. Example of an unavoidable PyLint warning is if you do not use the passed in datetime if you're listening for time change.

+# Home Assistant [![Build Status](https://travis-ci.org/balloob/home-assistant.svg?branch=master)](https://travis-ci.org/balloob/home-assistant) [![Coverage Status](https://img.shields.io/coveralls/balloob/home-assistant.svg)](https://coveralls.io/r/balloob/home-assistant?branch=master) [![Join the chat at https://gitter.im/balloob/home-assistant](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/balloob/home-assistant?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
 
-Home Assistant provides a platform for home automation. It does so by having modules that observe and trigger actors to do various tasks.
+[demo]: https://home-assistant.io/demo/
 
-It is currently able to do the following things:
- * Track if devices are home by monitoring connected devices to a wireless router (currently supporting modern Netgear routers or routers running Tomato firmware)
- * Track and control lights
- * Track and control WeMo switches
- * Track and control Chromecasts
- * Turn on the lights when people get home when the sun is setting or has set
- * Slowly turn on the lights to compensate for light loss when the sun sets and people are home
- * Turn off lights and connected devices when everybody leaves the house
- * Download files to the host machine
- * Open a url in the default browser at the host machine
- * Simulate key presses on the host for Play/Pause, Next track, Prev track, Volume up, Volume Down
- * Controllable via a REST API and web interface
- * Support for remoting Home Assistant instances through a Python API
- * Android Tasker project to control Home Assistant from your phone and report charging state.
+Home Assistant is a home automation platform running on Python 3. The goal of Home Assistant is to be able to track and control all devices at home and offer a platform for automating control.
 
-![screenshot-states](https://raw.github.com/balloob/home-assistant/master/docs/states.png)
-
-Current compatible devices:
- * [WeMo switches](http://www.belkin.com/us/Products/home-automation/c/wemo-home-automation/)
- * [Philips Hue](http://meethue.com)
- * [Google Chromecast](http://www.google.com/intl/en/chrome/devices/chromecast)
- * Wireless router running [Tomato firmware](http://www.polarcloud.com/tomato)
- * Netgear wireless routers (tested with R6300)
-
-The system is built modular so support for other devices or actions can be implemented easily.
-
-Installation instructions
--------------------------
-* The core depends on [PyEphem](http://rhodesmill.org/pyephem/) and [Requests](http://python-requests.org). Depending on the components you would like to use you will need [PHue](https://github.com/studioimaginaire/phue) for Philips Hue support, [PyChromecast](https://github.com/balloob/pychromecast) for Chromecast support and [ouimeaux](https://github.com/iancmcc/ouimeaux) for WeMo support. Install these using `pip install pyephem requests phue ouimeaux pychromecast`.
-* Clone the repository and pull in the submodules `git clone --recursive https://github.com/balloob/home-assistant.git`
-* Copy home-assistant.conf.default to home-assistant.conf and adjust the config values to match your setup.
-  * For Tomato you will have to not only setup your host, username and password but also a http_id. The http_id can be retrieved by going to the admin console of your router, view the source of any of the pages and search for `http_id`.
-* If you want to use Hue, setup PHue by running `python -m phue --host HUE_BRIDGE_IP_ADDRESS` from the commandline and follow the instructions.
-* While running the script it will create and maintain a file called `known_devices.csv` which will contain the detected devices. Adjust the track variable for the devices you want the script to act on and restart the script or call the service `device_tracker/reload_devices_csv`.
-
-Done. Start it now by running `python start.py`
-
-Web interface and API
----------------------
-Home Assistent runs a webserver accessible on port 8123. 
-
-  * At http://localhost:8123/ it will provide a debug interface showing the current state of the system and an overview of registered services.
-  * At http://localhost:8123/api/ it provides a password protected API.
-
-A screenshot of the debug interface:
-![screenshot-debug-interface](https://raw.github.com/balloob/home-assistant/master/docs/screenshot-debug-interface.png)
-
-All API calls have to be accompanied by an 'api_password' parameter (as specified in `home-assistant.conf`) and will
-return JSON encoded objects. If successful calls will return status code 200 or 201.
-
-Other status codes that can occur are:
- - 400 (Bad Request)
- - 401 (Unauthorized)
- - 404 (Not Found)
- - 405 (Method not allowed)
-
-The api supports the following actions:

-
-Architecture
-------------
-The core of Home Assistant exists of two parts; a Bus for calling services and firing events and a State Machine that keeps track of the state of things.
-
-![screenshot-android-tasker.jpg](https://raw.github.com/balloob/home-assistant/master/docs/architecture.png)
-
-For example to control the lights there are two components. One is the device_tracker that polls the wireless router for connected devices and updates the state of the tracked devices in the State Machine to be either 'Home' or 'Not Home'.
-
-When a state is changed a state_changed event is fired for which the device_sun_light_trigger component is listening. Based on the new state of the device combined with the state of the sun it will decide if it should turn the lights on or off:
-
-    In the event that the state of device 'Paulus Nexus 5' changes to the 'Home' state:
-      If the sun has set and the lights are not on:
-        Turn on the lights
-    
-    In the event that the combined state of all tracked devices changes to 'Not Home':
-      If the lights are on:
-        Turn off the lights
-        
-    In the event of the sun setting:
-      If the lights are off and the combined state of all tracked device equals 'Home':
-        Turn on the lights
-
-By using the Bus as a central communication hub between components it is easy to replace components or add functionality. For example if you would want to change the way devices are detected you only have to write a component that updates the device states in the State Machine.
-
-### Components
-
-**sun**
-Tracks the state of the sun and when the next sun rising and setting will occur.
-Depends on: latitude and longitude
-Action: maintains state of `weather.sun` including attributes `next_rising` and `next_setting`
-
-**device_tracker**
-Keeps track of which devices are currently home.
-Action: sets the state per device and maintains a combined state called `all_devices`. Keeps track of known devices in the file `known_devices.csv`. 
-
-**Light**
-Keeps track which lights are turned on and can control the lights.

+
+arduino:
+    port: /dev/ttyACM0
+
+Variables:
+
+port
+*Required
+The port where is your board connected to your Home Assistant system.
+If you are using an original Arduino the port will be named ttyACM*. The exact
+number can be determined with 'ls /dev/ttyACM*' or check your 'dmesg'/
+'journalctl -f' output. Keep in mind that Arduino clones are often using a
+different name for the port (e.g. '/dev/ttyUSB*').
+
+A word of caution: The Arduino is not storing states. This means that with
+every initialization the pins are set to off/low.

+
+This device tracker needs telnet to be enabled on the router.
+
+Configuration:
+
+To use the Actiontec tracker you will need to add something like the

+you can modify the home_interval variable.
+
+device_tracker:
+  platform: actiontec
+  host: YOUR_ROUTER_IP
+  username: YOUR_ADMIN_USERNAME
+  password: YOUR_ADMIN_PASSWORD
+  # optional:
+  home_interval: 10
+
+Variables:
+
+host
+*Required
+The IP address of your router, e.g. 192.168.1.1.
+
+username
+*Required
+The username of an user with administrative privileges, usually 'admin'.
+
+password
+*Required
+The password for your given admin account.
+
+home_interval
+*Optional
+If the home_interval is set then the component will not let a device
+be AWAY if it has been HOME in the last home_interval minutes. This is
+in addition to the 3 minute wait built into the device_tracker component.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This module provides an API and a HTTP interface for debug purposes.
+
+By default it will run on port 8123.
+
+All API calls have to be accompanied by an 'api_password' parameter and will
+return JSON. If successful calls will return status code 200 or 201.
+
+Other status codes that can occur are:
+ - 400 (Bad Request)
+ - 401 (Unauthorized)
+ - 404 (Not Found)
+ - 405 (Method not allowed)
+
+The api supports the following actions:
+
+/api - GET
+Returns message if API is up and running.
+Example result:
+{
+  "message": "API running."
+}
+
+/api/states - GET
+Returns a list of entities for which a state is available
+Example result:
+[
+    { .. state object .. },
+    { .. state object .. }
+]
+
+/api/states/<entity_id> - GET
+Returns the current state from an entity
+Example result:
+{
+    "attributes": {
+        "next_rising": "07:04:15 29-10-2013",

+    "state": "below_horizon"
+}
+
+/api/states/<entity_id> - POST
+Updates the current state of an entity. Returns status code 201 if successful
+with location header of updated resource and as body the new state.
+parameter: new_state - string
+optional parameter: attributes - JSON encoded object
+Example result:

-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This module provides an API and a HTTP interface for debug purposes.
-
-By default it will run on port 8123.
-
-All API calls have to be accompanied by an 'api_password' parameter and will
-return JSON. If successful calls will return status code 200 or 201.
-
-Other status codes that can occur are:
- - 400 (Bad Request)
- - 401 (Unauthorized)
- - 404 (Not Found)
- - 405 (Method not allowed)
-
-The api supports the following actions:
-
-/api/states - GET
-Returns a list of entities for which a state is available
-Example result:
-{
-    "entity_ids": [
-        "Paulus_Nexus_4",
-        "weather.sun",
-        "all_devices"
-    ]
-}
-
-/api/states/<entity_id> - GET
-Returns the current state from an entity
-Example result:
-{
-    "attributes": {
-        "next_rising": "07:04:15 29-10-2013",
-        "next_setting": "18:00:31 29-10-2013"
-    },
-    "entity_id": "weather.sun",
-    "last_changed": "23:24:33 28-10-2013",
-    "state": "below_horizon"
-}
-
-/api/states/<entity_id> - POST
-Updates the current state of an entity. Returns status code 201 if successful
-with location header of updated resource and as body the new state.
-parameter: new_state - string
-optional parameter: attributes - JSON encoded object
-Example result:
-{
-    "attributes": {
-        "next_rising": "07:04:15 29-10-2013",
-        "next_setting": "18:00:31 29-10-2013"
-    },
-    "entity_id": "weather.sun",
-    "last_changed": "23:24:33 28-10-2013",
-    "state": "below_horizon"
-}
-
-/api/events/<event_type> - POST
-Fires an event with event_type
-optional parameter: event_data - JSON encoded object
-Example result:
-{
-    "message": "Event download_file fired."
-}
