Wifi Smart Home Automation system with Manual Switches using NodeMCU ESP8266 & Blynk | IoT Projects

In this IoT project, I have shown how to make wifi smart home automation system with manual switches using NodeMCU ESP8266, Blynk, and relay module. With this internet of things project, you can control four home appliances from the Blynk app and manual switches with and without internet and you can also monitor real-time feedback in the Blynk App. So this is a very useful homemade smart home device that you can easily make with NodeMCU, Relay Module, Push Buttons.

For this ESP8266 home automation project, I have not used any custom design PCB. I have used the Blynk IoT applications to control the relay from the smartphone through WiFi. And instead of pushbuttons, you can also connect manual switches or touch sensors to control the home appliances.
