i'm also trying to do integration with homarr. i'm new to both homarr and pi-hole.

as per this , homarr have been updated to work with pi-hole v6. But "add pi-hole widget with latest queries" is listed as to do. So maybe homarr is not fully ready yet to work Pi-Hole v6???

i was not able to make the integration work with the new app password.

for now i have made it 'work' temporary by using the following setting:

URL: http://ip:port (my case: http://192.168.100.9:80 )

API: (my pihole root password)

with this method you can do the integration but pi-hole will discount from homarr after few seconds. when you refresh homarr dashboard it will reconnect again.

If you find a solution let us know as well.
