Adding PiHole (or AdGuard) next to HA on my RPI?

Hi,
I’m running Home-assistant Supervised on Raspbian GNU/Linux 11 (bullseye) (32BIT OS; on a harddisk)
This setup is many years old and updated only a few times per year.

Now I’d like to add Pi-Hole or ADGuard on to it. I just want to use that as a local DNS proxy with a sinkhole for Add-related URLs
This is just for a test. I may install it on a separate PI later. I want to see how it behaves first.

I tried curl -sSL https://install.pi-hole.net | bash
but then it said “this installer will transform your device into a network-wide ad blocker!”
I quickly stopped the script as it felt like it was going to reformat my harddisk

Questions:
As of today:

  1. what is the recommended solution? PiHole or AdGuard
  2. If I go for PiHole, would it be safe to just run the above-mentioned script? Would it leave my HA setup alone? or would it break it ?
  3. Did I read that correctly that HA-supervised will no longer be supported ?

My current versions:

  • Core: 2025.4.4
  • Supervisor: 2025.11.5
  • Operating System: <this is blank; I guess because the OS is not supported)
  • Frontend: 20250411.0

Any advise is greatly appreciated,

As of 2025.12, it is already unsupported as are 32-bit systems.

Did a quik forum search, very easy :wink:

Regarding to pi-hole → PI-hole installation - #6 by errut

You can install Adguard as a Add-on via HA webinterface.

That is blank because you are not running any version of HAOS.

I recommend you either never update again, as any further updates will break your supervised version…
Alternative is to get a new server that is 64bit, install using HAOS or Container which ARE supported, and restore a backup from your current supervised.

I also do not recommend installing PiHole or AdGuard, but that is a more personal issue. Never install software that messes with your DNS if you don’t understand it.

from what I see, the add-on just allows to manage an existing Pi-hole installation
It does not include the installation itself

Hi,

Correct. I used that 2 years ago with Pihole installed on a separate RPI3.
Pi-hole does not have a build in (container) install procedure on a HA OS system as far as I know.

AdGuard can be installed via Add-Ons
