Pi-Hole V6 uses a completely new api. Can you add support for this?
Give this old thing a bump as v6 is now being installed and causing a few hiccups. Would be good to get HA connection working again.
For anyone else who can’t wait, a temp solution is here:
This is a custom integration that restores access to a pi-hole running v6. I found I had to manually install it as the HACS install of the integration didn’t work as expected.
Maybe someone can update the official version by looking at this one?
Don’t hesitate to create an issue if an error occurs during the installation 
Don’t have a github account, and don’t really remember the details. Just that a manual install worked fine for me. Thanks for the addon.
