Built home automation on top of your devices:
* Keep a precise history of every change to the state of your house
The system is built modular so support for other devices or actions can be implemented easily. See also the [section on architecture](https://home-assistant.io/developers/architecture.html) and the [section on creating your own components](https://home-assistant.io/developers/creating_components.html).
If you run into issues while using Home Assistant or during development of a component, reach out to the [Home Assistant help section](https://home-assistant.io/help/) how to reach us.
The last command will start the Home Assistant server and launch its web interface. By default Home Assistant looks for the configuration file `config/configuration.yaml`. 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.
