An addon to remove the duplicate or unwanted or guest devices from Network overview page,
In my case usually my main router acts a DHCP server. Somehow when there is no internet TP-Link Deco’s starts giving out random IP’s for the same the same device with some random mac address. This makes a lot of redundant entries.
I usually run "sudo sqlite3 /etc/pihole/pihole-FTL.db “DELETE FROM network” probably every 10 days to remove unwanted entries from network page.
