pi-hole-control

Control Pi-hole with a push button.

Enables and disables Pi-hole with a physical push button connected on GPIO pin 40. A LED on pin 38 shows the current state.

Tested with:

• Pi-hole 2.9.5
• Python 2.7.9
• Raspberry Pi 2 running Raspbian Jessie

Features

• Uses the command line utility pihole to enable and disable DNS blocking
• Status polling to set LED state if Pi-hole was disabled through web interface
• Runs as system service (see scripts/init.d)

Installation

1. Install Pi-hole ad-blocking software:

   curl -L install.pi-hole.net | bash
   

2. Copy this file to /home/pi

   or wherever you prefer, e.g. /usr/local/bin

3. Connect button and LED:

   • wire a normally open push button to GPIO pin 40 and ground
   • wire a LED to a resistor to GPIO pin 38 and ground

4. Install script as system service:

   if this script was not installed in /home/pi: change $DIR and $LOG_DIR in pihole-control script.

   sudo copy ./scripts/init.d/pihole-control /etc/init.d/
   sudo chmod 755 /etc/init.d/pihole-control
   sudo update-rc.d pihole-control defaults
   

5. Start daemon

   sudo service pihole-control start
   

6. Press the button to disable/enable Pi-hole DNS blocking as needed

TODO

• Use Pi-hole API once released instead of pihole utility
