The difference between a condition and a trigger can be confusing. The difference is that the trigger looks at the event that is happening, ie a car engine turning on. Conditions looks at the current state of the system, ie is the car engine on.

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.

Scanning for connected devices is easy to setup. See the instructions for our [supported routers][routers] or [scan the network using nmap][nmap]. This approach does have its limitations. It will only be able to detect if a device is home. It also struggles with iPhones because they disconnect from the WiFi if idle, marking them as not home while they are not.

Home Assistant currently supports two third party services for presence detection: [OwnTracks][ha-owntracks] and [Locative][ha-locative]. 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.
