i use nmap and Asus-WRT for device tracking and i have noticed recently that my windows PC is always showing as Home when its switched off. The reason i use both is because nmap is a little unreliable with iPhone devices as everyone knows.
I have checked nmap by executing it on the Pi and it cannot locate the Windows machine as online, so i checked my router and there is an entry in the ARP cache which never gets cleared. I dont know why this is happening (could be pihole as it never used to do this and that is the only recent change on the network), however its messing up my automations with my lights as the work on the device being home/not_home etc…
Is there a way to exclude a certain IP from Asus-WRT device tracker?
