By default, Home Assistant will try to detect your location from IP address geolocation. Home Assistant will automatically select a temperature unit and time zone based on this location. You can overwrite this by adding the following information to your `configuration.yaml`:

```yaml
homeassistant:
  latitude: 32.87336
  longitude: 117.22743
  elevation: 430
  unit_system: metric
  time_zone: America/Los_Angeles
  name: Home
  whitelist_external_dirs:
    - /usr/var/dumping-ground
    - /tmp
```
