Known_devices and not traceable Mac addresses

Configuration
1

Hi All,

in known_devices.yaml I have some Mac addresses that are not visible in router dhcp list but are add in this .yaml file. Also when I visit https://macvendors.com they don’t find the vendor

For example (first 3 to check vendor)

6A:C3:D7
2A:48:5D
18:B4:30

Im running some Add-Ons inside HA like:

AdGuard
MariadB
Mosquitto Broker
HA Google Backup

Will those Add-Ons (dockers) creates random Mac addresses so those will pick up by HA?

Did you take bluetooth devices into consideration? Could also be from a phone that randomly changes MAC address at specific interval (which lots of phones do nowaday as far as I read)

ohh don’t know. never heard of this. How can I check this?

I don’t have platform: bluetooth_tracker running…

Removed the unknown addresses and disabled BLT. Restart HA and the Mac addresses are back. So something in the network gives me the Mac addresses…
