ESP32 + OLED Display: Display Weather from Home Assistant

Ever wanted a sleek, always-on display showing the current weather right from your Home Assistant dashboard? I did—and after some tinkering, I built one using an ESP32 and a tiny OLED screen. In this guide, I’ll walk you through the process, sharing pitfalls I encountered (like why my first attempt showed gibberish instead of temperatures) and how to avoid them. Why This Project? I love having ambient displays around my home that show useful info without needing to open an app.
