Hey friends in this tutorial I will show you how to make Blynk2.0 ESP32 WiFi, IR Remote and Manual Control Home Automation with Feedback System.
I will also show you how to configure and Reset WiFi connection of ESP32 with Blynk IOT 2.0 Application.
No Hard Coding required for WiFi Network Connection.
You will be able to control your Appliances, Devices with Smartphone Blynk application from any where around world and Manual Switches as well.
I have designed PCB For this project which makes this project very simple, compact and easy to use and install. This PCB can be used for multiple projects with ESP32 Nodemcu Board.

PCB Schematic:
Reset / Reconfigure WiFi Network Credentials Blynk 2.0:-
As in the code I have set GPIO pin 34 to bring ESP32 in Setup mode.
Connect GPIO 34 to GND for 10 Sec and you will find Blue LED blinking, that means its in setup mode.
You can now reset WiFi Credentials with Blynk IOT Application as shown in video.
