eink-weather-display | Battery-powered E-Ink weather display for our home

Download correct image from here: https://www.raspberrypi.com/software/operating-systems/b. Flash it to an SD card with balenaEtcher https://www.balena.io/etcher/ (or use RPIs own flasher). Boot the raspberry, and do initial setup. In your router, make sure to assign a static local IP address for the device. Install display updating code. or sudo apt install git and. You can create a limited Github personal access token, which only can clone that repo. I found git to be the easiest, it was easy to just git pull any new changes. ~pip install pipenv~ Edit: I wasn't able to get pipenv working due to pijuice being system-wide package. Ended up going with all-system-wide packages. cd eink-weather-display && pip install Pillow==9.3.0 google-cloud-logging requests python-dotenv pytz Install Python deps. Setup env variables: cp .env.example .env and fill in the details. Follow installation guide from https://www.waveshare.com/wiki/10.3inch_e-Paper_HAT to get the E-Ink display working. After install, test that the demo software (in C) works. To allow PIJuice to turn on without a battery, go to general settings and enable "Turn on without battery" or similar option. Make sure to use correct PIJuice battery profile (PJLIPO_12000 for me).

Boot the raspberry, and do initial setup
sudo raspi-config Setup Wifi SSID and password (System options) Update locales, timezones, etc (Localisation options) Enable SSH server (Interface options) Enable overlayfs (Performance options) to make the FS read-only.
In your router, make sure to assign a static local IP address for the device

To allow PIJuice to turn on without a battery, go to general settings and enable "Turn on without battery" or similar option.
Make sure to use correct PIJuice battery profile (PJLIPO_12000 for me) If using pijuice_cli, remember to apply changes! It was quite hidden down below.
Test that the PIJuice works with battery too
cd rasp/IT8951 and follow install instructions (inside virtualenv if using one)
Pijuice setup using pijuice_cli. Remember to save the changes inside each setup screen! System events ~Low charge, Low battery voltage and No power: SYS_FUNC_HALT_POW_OFF (docs: https://github.com/PiSupply/PiJuice/blob/master/Software/README.md#user-functions)~. Edit: these seemed to shutdown the device every once in a while. Everything worked more stable without setting any of these. ~Wake-up alarm: every day at 04:00 UTC (6AM Helsinki time in the winter, 7AM in the summer)~ Edit: code will set these, edit main.py
After that's done, you can test the PiJuice + E-Ink display together.
Setup crontab. Run refresh on boot, and shutdown device if on battery. @reboot (cd /home/pi/eink-weather-display/rasp; ./wait-for-network.sh; python main.py;) >> /home/pi/cron.log 2>&1 # Every minute * * * * * (cd /home/pi/eink-weather-display/rasp; python shutdown_if_on_battery.py;) >> /home/pi/cron.log 2>&1
cd rasp/usb-it8951/ and follow README.md instructions to get it build and working. Build it in Raspberry Pi. Find which /dev/sdX your usb device is, and change all commands from main.py accordingly
sudo apt install imagemagick
Finally, edit main.py to have correct paddings. Due to the physical installation, not all pixels of the E-Ink display are visible.
