Aura

The modifications are all based off the original Aura that can be found at https://github.com/Surrey-Homeware/Aura

New features were added and some of the original UI code was modified to make user colour selection easier.

New Features

1. JSON has been updated to auto adjust buffers for weather data
2. Colours are now super easy to adjust in the firmware.
3. Update timer was lengthened to 15 minutes (Open-Meteo only updates hourly)
4. Added WiFi signal strength indicator top right corner of TFT
5. Added hourly UV graph above temerature box
6. Weekday low/high now have trigger points and specific colours to match
7. Hourly temp has trigger for low/high with specific colours
8. Hourly POP% has trigger points/colours to cover range from 40% to 80%+
9. TFT_eSPI folder contains the User_Setup. for ILI9431, and for ST7789 (remove the _ST7789 to use)

All user adjustable settings documentmented lines in 33-69

Sample display images using existing defaults:

Aura is a simple weather widget that runs on ESP32-2432S028R ILI9341 devices with a 2.8" screen. These devices are sometimes called a "CYD" or Cheap Yellow Display.

This is just the source code for the project. This project includes a case design and assembly instructions. The complete instructions are available here: https://makerworld.com/en/models/1382304-aura-smart-weather-forecast-display
