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 (
If you’re on Debian or Ubuntu, you might have to install the packages for
nmap. Do so by running
$ sudo apt-get install net-tools nmap. On a Fedora host run
$ sudo dnf -y install nmap.
To use this device tracker in your installation, add the following to your
# Example configuration.yaml entry device_tracker: - platform: nmap_tracker hosts: 192.168.1.1/24
- hosts (Required): The network range to scan in CIDR notation, eg.
- home_interval (Optional): The number of minutes nmap will not scan this device, assuming it is home, in order to preserve the device battery.
- exclude (Optional): Hosts not to include in nmap scanning.
A full example for the
nmap tracker could look like the following sample:
# Example configuration.yaml entry for nmap device_tracker: - platform: nmap_tracker hosts: 192.168.1.1/24 home_interval: 10 exclude: - 192.168.1.12 - 192.168.1.13
See the device tracker component page for instructions how to configure the people to be tracked.
