Build a Smart Weather Station with ESP32 and DHT11 OLED Display
Introduction I’ve always been slightly obsessed with knowing the exact temperature of my office. Not the outside weather — I can open a window for that — but the microclimate around my desk, where the Wi‑Fi router and the afternoon sun conspire to turn summer afternoons into a slow roast. A few months ago I threw together a bare DHT11 dangling from my ESP32, just spitting readings to the serial monitor.
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.
