Smart Home Automation with Google Assistant & Alexa using NodeMCU Esp8266 (Manual + Voice).
In this loT projects, I have shown you how to make the smart home with Google Assistant & Alexa using NodeMCU ESP8266 to control relays with voice commands and manual switches. I have used all the free tools for this loT-based home automation system.
Required Components for each room for this NodeMCU home automation
1. NodeMCU
2. 4-channel 5V SPDT Relay Module
3. Switches or Push buttons.
