As per Pi-Hole’s API, it seems that one can both fetch information & update its status, namely get the status (is update needed, version information, etc.) and make changes to the hole’s configuration like whitelist a domain, blacklist a domain, etc.
This feature’s request suggested solution is to replace the current package by @fabaff with the one developed here
This will allow for better pi-hole support by HASS all around IMHO.
