I am using nmap for device_tracker. I got all the devices tracked in the known_devices.yaml except my Windows 10 laptops, desktop. Is that due to the firewall software in Windows 10?
I had the same but with samba share not working due to Windows 10 sharing policy.
I needed to activate the SMB feature which worked for me. See the following guide
