Home Assistant Community Add-on: Pi-hole

mmhhh I have two instances of HASSIO, on my main I use Adguard, on my second I use pi-hole. And then I use as DNS address 1 the address of HASSIO main, and DNS address 2, the address of HASSIO second

SO from HASSIO main, I guess I can’t access the HASSIo/PI-HOLE on the second? Because I wish to have the 2 switches (to turn on/off Adguard and turn on/off pihole), only in HASSIO main

Of course I will not use localhost, but just the IP address 192.168.1.x
