This project implements a smart home automation system for controlling fans and switches using Alexa integrated with Cardio software. Voice commands are handled through combined Alexa skills, enabling both individual device control and scene-based automation.
An ESP8266/ESP32 microcontroller communicates with Cardio software to execute switching commands via relay modules. A DHT11 temperature and humidity sensor continuously monitors environmental conditions. Based on preset temperature thresholds, the fan is automatically controlled to improve comfort and energy efficiency.
Users can also monitor real-time temperature and humidity data through a dashboard. The system supports manual, voice, and automated control modes.
