Home Automation using Amazon Alexa:

How it works:

User speaks a command to Alexa, triggering an action, like turning on a light. The Alexa Skill interprets the command and sends it to the AWS IoT platform. AWS IoT forwards the command securely to the ESP32 connected to the user’s home Wi-Fi. Upon receiving the command, the ESP32 processes it and translates the command into an IR signal to control an IR-enabled device, like a TV or air conditioner.

The IR signal is emitted to control the targeted device. After executing the command, the ESP32 sends feedback or status updates back through AWS IoT. The user may receive confirmation via the Alexa-enabled device or a visual interface indicating the action’s completion.
