Home Automation using NodeMCU ESP8266 and Blynk 2.0 with real-time feedback | IoT Projects 2021

In this IoT project, I have shown how to make the Home Automation using NodeMCU ESP8266 and Blynk 2.0 to control 4 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.

For the ESP32 Blynk 2.0, please refer to the following video
• Home Automation using ...
Important points:
**In code, you have to update only the BLYNK_TEMPLATE_ID & BLYNK_DEVICE_NAME as shown in the video.
**Keep all the 9 files (.ino & .h) in the same folder.
**You can only control the appliances if the WiFi is connected.
**Please take proper safety precautions while working with high voltages.
During this internet of things tutorial video, I have explained all the steps to configure the new Blynk 2.0 platform for any ESP8266 home automation system. Also explained how to create templates, and add Datastreams (Virtual Pin) in the Blynk IoT cloud account. If the NodeMCU connected with WiFi then you can control the relays from anywhere in the world. And you can also monitor the real-time feedback in the Blynk IoT applications. So with this smart house project, you can convert any appliance to IoT devices and control them through the internet.
