For some reason, the integration does not show any devices.

Nmap is installed and working in the HA docker container, and scanning the specified subnet shows a number of devices:

The only log message I see is that it is taking more than 10 seconds:

Logger: homeassistant.components.sensor
Source: runner.py:189
integration: Sensor (documentation, issues)
First occurred: 16:45:25 (1 occurrences)
Last logged: 16:45:25

Setup of sensor platform network_scanner is taking over 10 seconds.

However, after leaving the intergration for well over 20 mins it sill shows 0

could you help confirm if the version you are using is 1.0.7. This plugin is now available on HACS as well, you can get it up to date through it. https://hacs.xyz/

I can confirm i'm using 1.0.7 and installed it through hacs

i faced similar issue when my sophos firewall was blocking the scan requests. could you help check if you have any firewall that's blocking, or create a firewall rule to allow.

Good morning ! Can anyone help me? I have the same problem.. Let me explain: I have a local network in 10.0.0.x, and with a VPN, we reach an extent of 120 range, of 10.11.x.x (example: 10.11.47.2, 10.11.95.2, etc.) I can ping them using ssh, but nothing is found when scanning when I put 10.11.47.0/24.. Any idea?

I don't believe so. As I demonstrated in the initial post, I was able to run a ping scan from the home assistant docker container to the range I am trying to scan.

Could you enable debug log and see anything unusual?

so, I've done a bit of experimenting. It looks like hosts are dropped if they don't contain a mac address in the nmap scan. Nmap is only able to get the mac address for a device if it's on the same subnet. To demonstrate I added lines 96 and 97 to the sensor.py file:

The result was
