Does anyone have an explanation for these messages?

I've test a nmap from the container on the host network, it takes about 46sec, and changing capabilities NET_RAW etc.. has no effect,
finally I've tested nmap -sn -n -PS22,80,443 -T4 192.168.1.0/24 and boom 6 sec with all the devices on my network... so in sensor.py :
def scan_network(self):
"""Scan the network and return device information."""
self.nm.scan(hosts=self.ip_range, arguments= '-sn -n -PS22,80,443,5555,8008,8443 -T4')
devices = []
restart the HA container, and now no more message and my container is 100% available really faster
but the issue is that you don't have hostname anymore, if you have PTR records you can replace -n by -R and add --dns-servers ip of your dns server

[TheFab21]

I've create a PR : in order to have the hostname you must have PTR records set on your dns server.

Same here. But your PR is not approved jet, right? @TheFab21 ?

[TheFab21]

you're right, but you can edit by your side in HA

@TheFab21
seems to work.

Just download first -zip code instead official version, then exchange your sensor.py changed file.
