Google Maps Location Sharing


The google_maps platform allows you to detect presence using the unofficial API of Google Maps Location Sharing.

Setup

You first need to create an additional Google account and share your location with that account. This integration will use that account to fetch the location of your device(s).

  1. You have to setup sharing through the Google Maps app on your mobile phone. You can find more information here.
  2. You need to use the cookies from that account after you have properly authenticated which you can retrieve with either Export cookies for Firefox (make sure that “Prefix HttpOnly cookies” is unchecked) or cookies.txt for Chrome/Chromium.
  3. Save the cookie file to your Home Assistant configuration directory with the following name: .google_maps_location_sharing.cookies. followed by the slugified username of the NEW Google account. Make sure to use the .com TLD (e.g., maps.google.com), otherwise the cookie won’t be able to provide a valid session.
    • For example: If your email address was [email protected], the filename would be: .google_maps_location_sharing.cookies.location_tracker_gmail_com.

Configuration

To integrate Google Maps Location Sharing in Home Assistant, add the following section to your configuration.yaml file:

# Example configuration.yaml entry
device_tracker:
  - platform: google_maps
    username: YOUR_USERNAME

Once enabled and you have rebooted devices discovered through this integration wil be listed in the known_devices.yamlfile within your configuration directory.

They will be created with indentifiers like google_maps_<numeric_id>. To be able to properly track entities you must set the track attribute to true.

Configuration Variables

username

(string)(Required)

The email address for the Google account that has access to your shared location.

max_gps_accuracy

(float)(Optional)

Sometimes Google Maps can report GPS locations with a very low accuracy (few kilometers). That can trigger false zoning. Using this parameter, you can filter these false GPS reports. The number has to be in meters. For example, if you put 200 only GPS reports with an accuracy under 200 will be taken into account - Defaults to 100km if not specified.

scan_interval

(integer)(Optional)

The frequency (in seconds) to check for location updates.

Default value:

60

As of release 0.97 Google passwords are no longer required in your configuration. Users coming from earlier releases should only remove the password entry from their configuration file (username is still required) and restart Home Assistant. The cookie file previously generated should still be valid and will allow the tracker to continue functioning normally until the cookie is invalidated.
