+As an alternative to the router-based device tracking, it is possible to directly scan the network
+for devices by using Nmap. The IP addresses to scan can be specified in any format that Nmap understands,
+including the network-prefix notation (`192.168.1.1/24`) and the range notation (`192.168.1.1-255`).
+
+If you're on Debian or Ubuntu, you might have to install the packages for arp and nmap. Do so by
+running `apt-get install net-tools nmap`.
+
+```yaml
+# Example configuration.yaml entry
+device_tracker:
+  platform: nmap_tracker
+  hosts: 192.168.1.1/24
+  home_interval: 10
+```
+
+`home_interval` is an optional value set in minutes.  This will be the number of minutes nmap will not
+scan this device, assuming it is home, in order to preserve the device battery.
+
+See the [device tracker component page](/components/device_tracker.html) for instructions how to
+configure the people to be tracked.
