This project is a professional-grade solution for smart home enthusiasts and developers seeking to integrate traditional appliances into an IoT ecosystem without compromising safety or manual usability.

The Smart IoT Fan Controller enables full wireless control of a standard 220V AC fan, including its three speed levels and oscillation (swing) feature. Built on the robust ESP32 platform, this project utilizes MQTT protocol for seamless integration with any smart home dashboard or automation system, including mobile apps, Node-RED, or cloud-based platforms like HiveMQ.

Unlike many DIY smart control projects, this system is designed with real-world safety, reliability, and usability in mind. It implements a hybrid control system where the user can switch between manual and smart modes using a built-in SPDT relay logic. In case of failure, power loss, or Wi-Fi issues, the system is engineered to fall back to manual operation (using a reset button or simply unplug and plug the power cable), ensuring uninterrupted fan control without requiring technical knowledge from the end user.

This project is not just about turning a fan on or off — it's about creating a resilient and intelligent system architecture that ensures safety, ease of use, and future expandability.
