Setup Basic Information

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:

homeassistant:
  # Omitted values in this section will be auto detected using freegeoip.io

  # Location required to calculate the time the sun rises and sets
  latitude: 32.87336
  longitude: 117.22743

  # Impacts weather/sunrise data (altitude above sea level in meters) 
  elevation: 430

  # 'metric' for Metric, 'imperial' for Imperial
  unit_system: metric

  # Pick yours from here:
  # http://en.wikipedia.org/wiki/List_of_tz_database_time_zones
  time_zone: America/Los_Angeles

  # Name of the location where Home Assistant is running
  name: Home

Password protecting the web interface

First, you’ll want to add a password for the Home Assistant web interface. Use your favourite text editor to open configuration.yaml and edit the http section:

http:
  api_password: YOUR_PASSWORD

If you decide to expose your Home Assistant instance to the internet and forget to set a password, your installation could be accessed by everybody.

See the HTTP component documentation for more options, such as the use of HTTPS encryption.
