I made my old fan smart - WiFi control high voltage devices with ESP32

🔧 DIY smart fan project — ESP32, relays, and Home Assistant

⚠️ Safety Warning
This project involves working with high voltage (mains power). Do not touch the relay module or any exposed wiring while it’s connected to live power.
Always disconnect the fan from power before wiring or making adjustments.
