Tibber Price eink display

Inspired by myself but driven by https://www.youtube.com/techpirat

Preconditions

• Raspberry Pi Zero WH or Pi Zero 2 WH with Raspberry Pi OS (Bookworm)
• 7.5 eink display with red/black (Waveshare 7.5inch HD e-Paper HAT (B))
• HAT of the display that is on top of your Raspberry

Steps to install

• Install Raspberry Pi OS (UI not needed, so it's best to boot in text mode) - Min. Bookworm to get Python 3.11!
• Configure the basics using HDMI+Keyboard (or setup the Pi using SSH directly from the SD card)
  • Open raspi-config
    • Setting up SSH
    • Setting up Wifi
    • Enable SPI (required to connect the Waveshare Display!)
• Install required python packages

apt update
apt install python3-pil python3-matplotlib python3-requests

• Clone this repository
• Create Tibber API key at least with homes and price scope. Additional scopes are not used!
  • Put your tibber key in the file configuration.py!
• Run the create_price_chart.py to create the first chart
• Run the chart_to_display.sh to display the chart on the eink display

Optional: Disable the LED

Edit the /boot/config.txt file. Add to the end (if not existend) under [all]:

dtparam=act_led_trigger=none
dtparam=act_led_activelow=on

Run frequently with crontab

Open the cron of the user with crontab -e. And add the following lines:

0 * * * * cd tibber-eink-display/ && python3 ./create_price_chart.py && python3 ./chart_to_display.sh

This updates the chart every hour and displays it on the eink display.
