Replicate AdGuard Home settings into Home Assistant AdGuard Home Addon

I run 2 copies of AdGuard Home for ad-blocking on my local network. I didn't want to have to duplicate settings across the 2 instances I run.

I discovered adguardhome-sync which allows settings to be synchronised to replica instances. Neat!

But I hit a problem with the instance I had running as a Home Assistant Addon.

The instance I run as a replica is via a Home Assistant Addon and I wasn't sure how to get the config to work properly.

The base docker image for the sync app (bakito/adguardhome-sync) shows a yaml config file. So I started to create it:

cron: "*/10 * * * *"

runOnStart: true

origin:
  url: http://nuc.brunty.local:3000
  username: [insert your own username here]
  password: [insert your own password here]

replica:
  # url of the replica instance
  url: [insert your own replica URL here]
  username: [insert your own username here]
  password: [insert your own password here]

Now, the origin instance running via nuc.brunty.local was easy enough, I'd set that up myself in Portainer. So I configured the port, credentials etc.

But the instance running as a replica via I hadn't setup myself. I'd just clicked some buttons in a UI within Home Assistant.

I'd installed it via the addon. And I needed to know the port that the web interface ran on. I also needed a username and password.

I searched online, and tweeted out asking if anyone had done it before.

It seems like no-one had posted anything anywhere.

So, I searched the addon issues and found this: https://github.com/hassio-addons/addon-adguard-home/issues/201

It is the Home Assistant credentials, assuming you have exposed the web interface on a port.

Oh, it uses Home Asssitant credentials? Neat.

I went back to the addon page and noticed that there was an option to "Show disabled ports"

So I turned that option on and a "Web interface" option appeared. So I configured that there. Neat!

I also disabled SSL as I don't need it locally (this isn't accessible outside of my local network).

Now, I didn't want to use my main Home Assistant user account for this as that's an owner (principle of least privilege yo!)

So I setup a new user as a regular user, no admin permissions or anything. I can now use that username and password to access AdGuard Home!

So, here's my config for the sync setup:

adguardhome-sync.yaml:

cron: "*/10 * * * *"

runOnStart: true

origin:
  url: http://nuc.brunty.local:3000
  username: [insert your own username here]
  password: [insert your own password here]

replica:
  # url of the replica instance
  url: http://homeassistant.brunty.local:3000
  username: [insert your own username here]
  password: [insert your own password here]

Winner!
