Configure Home Assistant

When launched for the first time, Home Assistant will write a default configuration file, called configuration.yaml, enabling the web interface and device discovery. It can take up to a minute for your devices to be discovered and appear in the user interface.

The configuration.yaml is written in YAML, stored in .homeassistant, and can be modified with a text editor.

See the components overview page to find sample entries for your devices and services. For a sensor that is showing random values, the entry would look like the sample below:

  - platform: random

The Setting up devices part contains the additional documentation details about adding devices and services and customization.

For further details about configuration, please take a look at the configuration documentation.
