In this IoT project, I have shown how to make the Home Automation using NodeMCU ESP8266 and Blynk 2.0 to control 1 relays with real-time feedback. For this smart home project, I have used the FREE plan of the new Blynk IoT platform, so you can easily make this simple IoT-based home automation system to control the appliances with WiFi and manual switches.
