IoT Smart Home Automation

ESP32 + Firebase for app-controlled lights, fans, and sensors.

Synopsis

Home automation without a hub — app and MCU both speak directly to Firebase.

About this project

Control home appliances from a Flutter mobile app via Firebase Realtime Database. ESP32 reads sensor data (DHT11 temperature/humidity, PIR motion), publishes to Firebase, and listens for relay commands. Flutter app shows live sensor feed and relay toggles.
