pihole-oled

Hardware

The OLED display is connected via I2C with 4 wires: SDA, SCL, 3.3V and GND. There is no reset pin. The "HAT" is made with a 8-pin female header, a piece of proto-board and short wires. There is nothing fancy here.

Installation

⚠️ This project requires a Raspberry Pi with Pi-hole installed, the I2C bus enabled and Python 3.5.

Software requirements

If you do not have pip3 installed, start by installing it:

sudo apt-get install python3-pip

If you do not have pipenv installed, install it too:

pip3 install --user pipenv

Note: the command above keeps everything into a ~/.local directory. You can update the current user's PATH by adding the following lines into your .bashrc (or equivalent):

export PY_USER_BIN="$(python -c 'import site; print(site.USER_BASE + "/bin")')"
export PATH="$PY_USER_BIN:$PATH"

Now install a few libraries for Pillow:

sudo apt-get install libopenjp2-7 libtiff5

Project installation

Clone this project:

git clone https://github.com/willdurand/pihole-oled.git /home/pi/pihole-oled

Install the python dependencies:

cd /home/pi/pihole-oled
pipenv install

If you plug the OLED display and run the command below, you should see some information on the display:

pipenv run python3 main.py

You can exit the script with ctrl+c.

Systemd configuration

You can install a systemd service by copying the provided configuration file using the command below. This service will automatically run the python script mentioned in the previous section on boot:

sudo cp pihole-oled.service /etc/systemd/user/

Enable, then start the pihole-oled.service:

sudo systemctl enable /etc/systemd/user/pihole-oled.service
sudo systemctl start pihole-oled.service

Dev corner

This sections is only relevant if you intent to work on this project.

We use conda to ship a (hopefully) reproducible environment to work on this project. Start by installing conda, then create the environment for this project:

conda env create -f environment.yml

Do not forget to enable this environment:

conda activate

You should have python3 (3.5) and pipenv available now.
