Deprecation warning

This add-on is in a deprecated state!

The Pi-hole add-on is now deprecated and will no longer be supported, maintained and will not receive future updates or fixes.

Pi-hole used to be a great solution to filter network traffic, but it has been a challenge to keep/get it in a working state as an add-on.

Meanwhile, the AdGuard team published an alternative: AdGuard Home.

AdGuard Home as surpassed Pi-hole in terms of capabilities, features, and stability, and Home Assistant provides a good integration with AdGuard. Above all, the AdGuard Home team has been supportive in developing the add-on.

For those reasons, it is no longer viable to keep maintaining the Pi-hole add-on, which has been problematic at best.

We strongly recommend migrating to the AdGuard Home add-on, which is available in the add-on store.

About

Pi-hole is an advertising-aware DNS- and web server, meant to be run on a dedicated Raspberry Pi connected to your home network. Pi-hole lets you block advertisements for every device that connects to your network without the need for any client-side software.

This add-on is a port of Pi-hole to be able to run on Home Assistant and is based on Alpine Linux and is using Docker.

Installation

The installation of this add-on is pretty straightforward and not different in comparison to installing any other Home Assistant add-on.

  1. Ensure your Home Assistant device has a static IP and static external DNS servers!
  2. Search for the "Pi-hole" add-on in the Supervisor add-on store and install it.
  3. Start the "Pi-hole" add-on
  4. Check the logs of the "Pi-hole" add-on to see it in action.

Configuration

Note: Remember to restart the add-on when the configuration is changed.

Example add-on configuration:

log_level: info
update_lists_on_start: true
ssl: false
certfile: fullchain.pem
keyfile: privkey.pem
interface: eth0
ipv6: true
ipv4_address: ''
ipv6_address: ''
hosts:
  - name: printer.local
    ip: 192.168.1.5
  - name: router.local
    ip: 192.168.1.1
  - name: router.local
    ip: "FE80:0000:0000:0000:0202:B3FF:FE1E:8329"

Note: This is just an example, don't copy and paste it! Create your own!

Option: log_level

The log_level option controls the level of log output by the addon and can be changed to be more or less verbose, which might be useful when you are dealing with an unknown issue. Possible values are:

  • trace: Show every detail, like all called internal functions.
  • debug: Shows detailed debug information.
  • info: Normal (usually) interesting events.
  • warning: Exceptional occurrences that are not errors.
  • error: Runtime errors that do not require immediate action.
  • fatal: Something went terribly wrong. Add-on becomes unusable.

Please note that each level automatically includes log messages from a more severe level, e.g., debug also shows info messages. By default, the log_level is set to info, which is the recommended setting unless you are troubleshooting.

Using trace or debug log levels puts the dnsmasq daemon into debug mode, allowing you to see all DNS requests in the add-on log.

Option: update_lists_on_start

Download and process all configured ad block lists on add-on startup by setting this option to true. This will add startup time to your add-on but will give you the most recent versions of the ad block lists on start.

When this option is set to false you will still get updated lists once in a while. A scheduled task will take care of that.

Note: When starting the add-on for the very first time, the lists will be updated, regardless of the value of this option.

Option: ssl

Enables/Disables SSL (HTTPS) on the web interface of Pi-hole. Set it true to enable it, false otherwise.

Option: certfile

The certificate file to use for SSL.

Note: The file MUST be stored in /ssl/, which is the default

Option: keyfile

The private key file to use for SSL.

Note: The file MUST be stored in /ssl/, which is the default

Option: interface

Configures the interface the Pi-hole DNS server should be listening to. By leaving it empty, the add-on will try to auto-detect the interface to use.

Note: This option is in place in case auto-detection fails on your setup.

Option: ipv6

Set this option to false to disable IPv6 support.

Option: ipv4_address

Manually set the IPv4 address for Pi-hole to use. By leaving it empty, the add-on will try to auto-detect the interface to use.

Note: This option is in place in case auto-detection fails on your setup.

Option: ipv6_address

Manually set the IPv6 address for Pi-hole to use. By leaving it empty, the add-on will try to auto-detect the interface to use.

Note: This option is in place in case auto-detection fails on your setup.

Option: hosts

This option allows you create your own DNS entries for your LAN. This capability can be handy for pointing easy to remember hostnames to an IP (e.g., point printer.local to the IP address of your printer).

Add a list of hosts you want to add. Some hosts can have both IPv4 and IPv6 addresses. In that case, simply add the host twice (with both addresses).

See the example above this chapter for a more visual representation.

Sub-option: name

This option specifies the DNS name of the host you are adding. Its value could be a short style hostname like: printer or a longer one printer.local.

Sub-option: ip

The IP address this specified host must point to. Its value must be an IPv6 or IPv4 IP address.

Option: leave_front_door_open

Adding this option to the add-on configuration allows you to disable authentication on the admin interface by setting it to true and leaving the password empty.

Note: We STRONGLY suggest, not to use this, even if this add-on is only exposed to your internal network. USE AT YOUR OWN RISK!

Using the Pi-hole integration in Home Assistant

Home Assistant offers a Pi-hole integration that allows you to retrieve statistics and interact with your Pi-hole installation.

To enable this integration, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
pi_hole:
  host: localhost:4865
  api_key: ""

For more information and documentation about configuring this sensor, please check the documentation of Home Assistant.
