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.
It offers the following functionality through built-in components:
* Track if devices are home by monitoring connected devices to a wireless router (supporting [OpenWrt](https://openwrt.org/), [Tomato](http://www.polarcloud.com/tomato), [Netgear](http://netgear.com))
* Track and control [Philips Hue](http://meethue.com) lights
* Track and control [WeMo switches](http://www.belkin.com/us/Products/home-automation/c/wemo-home-automation/)
* Track and control [Google Chromecasts](http://www.google.com/intl/en/chrome/devices/chromecast)
* Track running services by monitoring `ps` output
The system is built modular so support for other devices or actions can be implemented easily. See also the [section on architecture](#architecture) and the [section on customizing](#customizing).
If you run into issues while using Home Assistant or during development of a component, reach out to the [Home Assistant developer community](https://groups.google.com/forum/#!forum/home-assistant-dev).
The last command will start the Home Assistant server and launch its webinterface. By default Home Assistant looks for the configuration file `config/home-assistant.conf`. A standard configuration file will be written if none exists.
If you are still exploring if you want to use Home Assistant in the first place, you can enable the demo mode by adding the `--demo-mode` argument to the last command.
After you got the demo mode running it is time to enable some real components and get started. An example configuration file has been provided in [/config/home-assistant.conf.example](https://github.com/balloob/home-assistant/blob/master/config/home-assistant.conf.example).
Your wireless router is used to track which devices are connected. Three different types of wireless routers are currently supported: tomato, netgear and luci (OpenWRT). To get started add the following lines to your `home-assistant.conf` (example for Netgear):
*Note on tomato:* Tomato requires an extra config variable called `http_id`. The value can be obtained by logging in to the Tomato admin interface and search for `http_id` in the page source code.
*Note on luci:* before the Luci scanner can be used you have to install the luci RPC package on OpenWRT: `opkg install luci-mod-rpc`.
Once tracking, the `device_tracker` component will maintain a file in your config dir called `known_devices.csv`. Edit this file to adjust which devices have to be tracked.
As an alternative to the router-based device tracking, it is possible to directly scan the network for devices by using nmap. The IP addresses to scan can be specified in any format that nmap understands, including the network-prefix notation (`192.168.1.1/24`) and the range notation (`192.168.1.1-255`).
