 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`).

-Host detection is done via Nmap's "fast scan" (`-F`) of the most frequently used 100 ports, with a host timeout of 5 seconds.

-To use this device tracker in your installation, add the following to your `configuration.yaml` file:
-
-```yaml
-# Example configuration.yaml entry
-device_tracker:
-  - platform: nmap_tracker
-    hosts: 192.168.1.0/24

-home_interval:
-  description: The number of minutes Nmap will not scan this device, assuming it is home, in order to preserve the device battery.
-  required: false

-## Examples

-A full example for the `nmap` tracker could look like the following sample:
-
-```yaml
-# Example configuration.yaml entry for Nmap
-# One whole subnet, and skipping two specific IPs.
-device_tracker:
-  - platform: nmap_tracker
-    hosts: 192.168.1.0/24
-    home_interval: 10
-    exclude:
-     - 192.168.1.12
-     - 192.168.1.13
-```
-
-```yaml
-# Example configuration.yaml for Nmap
-# One subnet, and two specific IPs in another subnet.
-device_tracker:
-  - platform: nmap_tracker
-    hosts:
-      - 192.168.1.0/24
-      - 10.0.0.2
-      - 10.0.0.15
-```
-
-In the above example, Nmap will be call with the process:
-`nmap -oX - 192.168.1.1/24 10.0.0.2 10.0.0.15 -F --host-timeout 5s`
