Configuring Home Assistant


When launched for the first time, Home Assistant will write a default configuration file 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 location of the folder differs between operating systems:

OS Path
macOS ~/.homeassistant
Linux ~/.homeassistant
Windows %APPDATA%/.homeassistant

If you want to use a different folder for configuration, use the config command line parameter: hass --config path/to/config.

Inside your configuration folder is the file configuration.yaml. This is the main file that contains components to be loaded with their configurations. Throughout the documentation you will find snippets that you can add to your configuration file to enable functionality.

You will have to restart Home Assistant for changes to configuration.yaml to take effect.

If you run into trouble while configuring Home Assistant, have a look at the configuration troubleshooting page and at the configuration.yaml examples.

Test any changes to your configuration files from the command line with hass --script check_config. This script allows you to test changes without the need to restart Home Assistant.
