PiholeDashboard

A simple web interface to quickly disable Pi-hole ad-blocking and show some basic stats. This was made with dark themes in mind.

Requirements

Raspberry Pi (this should work on other devices, but you'll need to adjust how the temperature and uptime stats are fetched for your device in the includes.php file for your respecitve system)
A working Pi-hole installation. See https://pi-hole.net/
php7.3
php-curl
git

Getting started

You can either host this application on the same Raspberry Pi where Pi-hole is installed, or set this up on a different machine. It is recommended to install alongside Pi-hole on the same Raspberry Pi. Below are the steps for both.

Install alongside Pi-hole on a Raspberry Pi

Note: Pi-hole already installs PHP and git, so it can be skipped.

SSH into your Raspberry Pi enter the following to php-curl: sudo apt-get install php-curl.
Next type in sudo usermod -aG video www-data. This is needed to fetch temperature data on a Raspberry Pi.
Next type in cd /var/www/html/.
Copy the PiHoleDashboard code to your machine: git clone https://github.com/obs0lete/PiholeDashboard.git piholedashboard.
Log into your Pi-hole (UI) and go to Settings > API/Web Interface.
Click on the Show API token button, then Yes, show API token.
Copy your API token.
Edit the includes.php and as follows:
- $piHole = ""; Set this to your Pi-hole URL. For example, http://pi.hole/admin
- $apiKey = ; Enter your API key here
In your SSH console, edit the /etc/lighttpd/lighttpd.conf with your editor of choice and enter the following: Note: Make sure to replace some.server with the FQDN that you will use to access this application.

$HTTP["host"] == "some.server" {
    # Ensure the Pi-hole Block Page knows that this is not a blocked domain
    setenv.add-environment = ("fqdn" => "true")
    server.document-root = "/var/www/html/piholedashboard/"
}

Note: If you want to access this via HTTPS, you will need to use the following instead of the above code. You will need to adjust the values of ssl.pemfile and ssl.ca-file to point to your certificates accorrdingly.

# Pi-hole Dashboard
$HTTP["host"] == "some.server" {
  # Ensure the Pi-hole Block Page knows that this is not a blocked domain
  setenv.add-environment = ("fqdn" => "true")

  # Enable the SSL engine with a LE cert, only for this specific host
  $SERVER["socket"] == ":443" {
    ssl.engine = "enable"
    ssl.pemfile = "/certs/combined.pem"
    ssl.ca-file =  "/certs/fullchain.pem"
    ssl.honor-cipher-order = "enable"
    ssl.cipher-list = "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH"
    ssl.use-sslv2 = "disable"
    ssl.use-sslv3 = "disable"
    server.document-root = "/var/www/html/piholedashboard/"
  }

  # Redirect HTTP to HTTPS
  $HTTP["scheme"] == "http" {
    $HTTP["host"] =~ ".*" {
      url.redirect = (".*" => "https://%0$0")
    }
  }
}

Next, edit the /etc/hosts file and add the IP address and FQDN of your Pi-hole, for example: 192.168.1.2 pi.hole
Go back to the Pi-hole UI and nvigate to Settings > Local DNS > DNS Records and add entry to resolve some.server to the same IP address of your Pi-hole.
Next, restart lighttpd by entering sudo systemctl restart lighttpd.
In a browser, go to http(s)://some.server and the Pi-Hole Daashboard should now be working.

Install on a separate server

Note: The web server setup is out of the scope of this guide. You will need to configure a working web server yourself. Note: Depending on the hardware this is running on, you may need to configure the $getTemp variable in the includes.php file with the correct commands to fetch the temperature for your system. Note: Depending on the hardware this is running on, you may need to configure the $upTime variable in the includes.php file with the correct commands to fetch the uptime for your system.

Install php7.3, php-curl, git and a web server such as nginx.

sudo apt-get install php7.3
sudo apt-get install php-curl
sudo apt-get install git
sudo apt-get install nginx

Copy the code to the location your web server's document root: sudo git clone https://github.com/obs0lete/PiholeDashboard.git
Log into your Pi-hole (UI) and go to Settings > API/Web Interface.
Click on the Show API token button, then Yes, show API token.
Copy your API token.
Edit the includes.php and as follows:
- $piHole = ""; Set this to your Pi-hole URL. For example, http://pi.hole/admin
- $apiKey = ; Enter your API key here
In a browser, access the site.

Usage

To disable Pi-hole ad-blocking, click on Disable. This will disable ad-blocking infinitely.

To (re)enable ad-blocking, click on Enable.

You can also specify how long you want to disable ad-blocking for, in minutes. In the text box, enter the amount of minutes you want to disable as-blocking for, then click on the Disable (mins) button.
