This is a short update, I will post technical details in next posts:

• I reworked PCBs, now they are 1cm shorter as well as fixed some other annoying things found in previous version
• Static analysis CI build went from 1 hour (and killed by GitHub CI so no results) to 4 minutes
• I think about using GUIslice (https://github.com/ImpulseAdventure/GUIslice) as a GUI lib because it supports RGB displays.
• ESP code will be done in Rust, simply because I hate Arduino libs; STM32 code is C++.
• Made a PoC for processing data on Raspberry Pi and showing data via Graphana (more info here: https://hackaday.io/project/198074-piweathershield in project description, manual is here: https://github.com/RobertGawron/HardwareDataLogger-RemoteProcessing/tree/main/Target)
• Massive refactor of the project's structure.
