Displays upcoming events, weather and air quality forecasts, and other useful daily information on an e-ink screen.
I used a Soldered Inkplate 5 Gen 2 but could probably be adapted to work with any e-ink screen that has a Wi-Fi antenna and runs Arduino.
There's two parts to the software: a small Arduino program to update the screen, and a command-line Linux program to fetch and assemble the daily information. The Linux program fetches data from a few places: Google Calendar, Open-Meteo, ChatGPT, etc. It then assembles this data into a few cards on a web page. Next, it runs a headless Chrome browser to capture a screenshot of the page. Finally, it saves the screenshot in a location where it can be served by a web server. The Arduino program wakes up once a day, connects to Wi-Fi, grabs the screenshot from the web server, updates it's display, and goes back to sleep.
