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.
