Setup basic information
As part of the default onboarding process, Home Assistant can detect your location from IP address geolocation. Home Assistant will automatically select a temperature unit and time zone based on this location. You may adjust this during onboarding, or afterwards at Settings > System > General.
If you prefer YAML, you can add the following information to your
homeassistant: name: Home latitude: 32.87336 longitude: 117.22743 elevation: 430 unit_system: metric currency: USD time_zone: "America/Los_Angeles" external_url: "https://www.example.com" internal_url: "http://homeassistant.local:8123" allowlist_external_dirs: - "/usr/var/dumping-ground" - "/tmp" allowlist_external_urls: - "http://images.com/image1.png" media_dirs: media: "/media" recordings: "/mnt/recordings" legacy_templates: false
You will not be able to edit anything in Settings > System > General in the UI if you are using YAML configuration for any of the following: name, latitude, longitude, elevation, unit_system, temperature_unit, time_zone, external_url, internal_url. Additionally, some options are only visible after “Advanced Mode” is enabled on your User Profile.

List of external URLs that can be fetched. URLs can match specific resources (e.g.,
http://10.10.10.12/images/image1.jpg) or a relative path that allows access to resources within it (e.g.,
http://10.10.10.12/images would allow access to anything under that path)
Reload Core Service
Home Assistant offers a service to reload the core configuration while Home Assistant is running called
homeassistant.reload_core_config. This allows you to change any of the above sections and see it being applied without having to restart Home Assistant. To call this service, go to the “Services” tab under Developer Tools, select the
homeassistant.reload_core_config service and click the “CALL SERVICE” button. Alternatively, you can press the “Reload Location & Customizations” button under Developer Tools > YAML.
