I first made this project using Raspberry Pi Zero and Python (link), and then I re-made it using ESP32 and Arduino. My weather dashboard shows the current weather and a bar chart of 5-day high and low temperatures. There's also a menu interface for switching Wi-Fi connections.

Hardware setup: ESP32 paired with a Nextion NX8048T050 HMI touchscreen display on UART2.

Features:

• Weather data fetching from Open-Meteo API
• Utilizes WiFi library for network connection management
• Utilizes Nextion GUI designing commands to draw a 5-day weather bar chart
• Automatic location detection via IPInfo.io API
• Geocoder for location name resolution via Nominatim API

The next step is to set up all the binaries/elf and RTOS from scratch without using the Arduino framework. I don't know how hard would it be. I hope I'll make it in a few weeks.
