Home Assistant can get information from your wireless router to track which devices are connected. There are three different types of supported wireless routers:

- [DD-WRT](/components/device_tracker.ddwrt.html)
- [tomato](/components/device_tracker.tomato.html)
- [netgear](/components/device_tracker.netgear.html)
- [luci (OpenWRT)](/components/device_tracker.luci.html)
- [TP-Link](/components/device_tracker.tplink.html)

You can also decide to directly scan the network for devices by using the [nmap scanner](/components/device_tracker.nmap_scanner.html).

To get started add the following lines to your `configuration.yaml` (example for Netgear):

```
device_tracker:
  platform: netgear
  host: 192.168.1.1
  username: admin
  password: MY_PASSWORD
```

Once tracking, the `device_tracker` component will maintain a file in your config dir called `known_devices.csv`. Edit this file to adjust which devices have to be tracked. Here you can also setup a url for each device to be used as the entity picture.
