The `gpslogger` device tracker platform allows you to detect presence using [GPSLogger](http://code.mendhak.com/gpslogger/). GPSLogger is an open source app for [Android](https://play.google.com/store/apps/details?id=com.mendhak.gpslogger) that allows users to set up a `GET` request to update GPS coordinates. This can be configured with Home Assistant to update your location.

To integrate GPSLogger in Home Assistant, add the following section to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
device_tracker:
  - platform: gpslogger
    password: !secret gpslogger_password
```
{% configuration %}
password:
  description: Separate password for GPS Logger endpoint. If provided using regular API password to contact endpoint will result in 401 response.
  required: false
  type: string
{% endconfiguration %}

## {% linkable_title Setup on your smartphone %}

Install [GPSLogger for Android](https://play.google.com/store/apps/details?id=com.mendhak.gpslogger) on your device.

After the launch, go to **General Options**. Enable **Start on bootup** and **Start on app launch**.

  GPSLogger Settings
</p>

Go to **Logging details** and disable **Log to GPX**. **Log to KML**, and **Log to NMEA**. Enable **Log to custom URL**.

  Logging Details
</p>

Right after enabling, the app will take you to the **Log to custom URL** settings.

<p class='img'>

  Log to custom URL details
</p>

The relevant endpoint is: `/api/gpslogger`

```text
https://[IP address Home Assistant]:[Port]/api/gpslogger?
   latitude=%LAT&longitude=%LON&device=%SER&accuracy=%ACC
   &battery=%BATT&speed=%SPD&direction=%DIR
   &altitude=%ALT&provider=%PROV&activity=%ACT
```

Add the above URL after you modified it with your settings into the **URL** field. Remove the line breaks as they are only there to make the URL readable here.

- It's HIGHLY recommended to use SSL/TLS.
- Use the domain that Home Assistant is available on the internet or the public IP address. This can be a local IP address if you are using an always on VPN from your mobile device to your home network.
- Only remove `[Port]` if your Home Assistant instance is using port 443. Otherwise set it to the port you're using.
- For Home Assistant only the above URL, as written, will work - do not add or remove any parameters.
- Make sure to include your [API password](/components/http/) if you have configured a password. Add `&api_password=[Your password]` to the end of the URL. 
- You can change the name of your device name by replacing `&device=%SER` with `&device=[Devicename]`.

If your battery drains fast then you can tune the performance of GPSLogger under **Performance** -> **Location providers**

A request can be forced from the app to test if everything is working fine. A successful request will update the `known_devices.yaml` file with the device's serial number.
