PiHole e-Paper Display

Outputs the result of pihole chronometer to a Waveshare 2.7 inch e-Paper hat.

Enable SPI Interface on the Raspberry Pi

Before connecting the e-paper display to the Raspberry Pi the SPI interface needs to be enabled. This can be accomplished by using the raspi-config command and selecting Interfacing options -> SPI -> Yes

Installation

sudo apt update -y && sudo apt install -y python3 python3-pil
git clone https://github.com/ca0abinary/raspi_pihole_epd.git

To make it run on a schedule:

cd raspi_pihole_epd
crontab -l > cronjobs
echo "* * * * * $(pwd)/display.py" >> cronjobs
crontab cronjobs

Files

• display.py
  • Main application, parses the output of pihole chronometer and displays on the result to the e-paper hat
• display-web.py
  • Displays the website graph using selenium, webdriver, and imagemagick
  • 4gray.png
    • Support for converting images to 4 grey (from adafruit article)
• EPD support files
  • epd2in7.py - if you have another type of display this file can be swapped out
  • epdconfig.py - config file from waveshare
  • FiraCore-Regular.ttf - mono-space font from the excellent FiraCode project. This can be swapped out for a standard font such as Roboto if the strings running off-screen bothers you. A mono-space font makes the chronometer output look nicer.
