Wireless Stack
As a backend developer, I rarely see hobby projects with such a clean separation of concerns. The way the ESP32 handles the deep sleep cycle and reliably pushes JSON payloads to the .NET Docker container is exactly how commercial products are built.
I absolutely love the clean, modern dashboard. It doesn't look like a typical, clunky DIY project – it feels like a premium app. Having real-time access to barometric pressure and humidity right from my phone, with zero lag, is fantastic. It's stable, reliable, and looks great.
Looking at the Weather32 repository taught me more about connecting hardware to a modern web stack than my university classes. The documentation is clear, and seeing how C++ on the microcontroller communicates with a C# backend was a huge 'aha' moment for me. Highly recommended for anyone learning IoT.
I've built several weather stations based on random tutorials, but this one takes the crown. Using the 18650 battery shield combined with the ESP32's low power modes means I don't have to run cables to my balcony anymore. The telemetry data is incredibly accurate and the UI is lightning fast.
