In this IoT project, I demonstrate how to set up Smart Home Automation with Alexa using the ESP8266 and Amazon Echo Dot. This ESP8266 Alexa Home Automation project solely relies on the Amazon Alexa App for controlling home devices with 4 relays. Even without the internet, you can manage devices with push buttons. Once the device is online, the NodeMCU ESP8266 auto-connects to WiFi, preserving the relay module’s last state.
Earlier we built Alexa Home Automation with fauxmoESP Library, but here we used Espalexa Library. I have designed the custom PCB for this project to make the device portable. I have also provided the complete schematic, PCB details, Gerber File, Bill of Materials and Source Code. The system works without any third-party IoT apps, making it straightforward for home automation setup.
