<p>The device tracker component offers presence detection for Home Assistant. It supports two different methods for presence detection: scan for connected devices on the local network and connect to third party service.</p>
<p>Scanning for connected devices is easy to setup. See the instructions for our <a href="/components/#presence-detection">supported routers</a> or <a href="/components/device_tracker.nmap_scanner/">scan the network using nmap</a>. This approach does have its limitations however, it will only be able to detect if a device is home. It also struggles with iPhones because they disconnect from WiFi if idle, marking them as not home when they actually are.</p>

<p>Home Assistant currently supports two third party services for presence detection: <a href="/components/device_tracker.owntracks/">OwnTracks</a> and <a href="/components/device_tracker.locative/">Locative</a>. OwnTracks is an app that you install on your iPhone or Android phone that allows you to push the location of your device to Home Assistant using an MQTT broker. An MQTT broker is an Internet of Things communication platform that you can <a href="/components/mqtt/#run-your-own">freely host yourself</a> or get <a href="/components/mqtt/#run-your-own">a private instance for free in the cloud</a>.</p>
