ESP8266 Project using Blynk IFTTT and Google Assistant | ESP 01 Home Automation 2021

In this IoT tutorial, I have made the ESP8266 Project using Blynk IFTTT and Google Assistant to control relays with voice commands or manual switches. To make this ESP-01 home automation system I have used all the FREE IoT applications.

NodeMCU Blynk control 4 relays

ESP32 Blynk control 8 relays with sensors

Important points:
1. In code, you have to update only the BLYNK_TEMPLATE_ID & BLYNK_DEVICE_NAME as shown in the video.
2. Uncomment GPIOs in the code as per the microcontroller (NodeMCU or ESP01).
3. Keep all the 10 files (.ino & .h) in the same folder.
4. Connect the GPIO-0 with GND before programming ESP-01.
**Please take proper safety precautions while working with high voltages.

During the video, I have explained the syntax for updating the Datastream Value in the Blynk cloud server so you can connect any Blynk projects with Google assistant through the IFTTT to control the appliances with the voice commands from anywhere in the world. For this internet of things project, I have used NodeMCU and ESP01. If the NodeMCU or ESP01 is connected with WiFi then you can control the relays from anywhere in the world from mobile, and monitor the real-time feedback in the Blynk IoT applications.

I really want to thank you. I have been watching your videos for 2 years and i learned a lot. I did a lot of your tutorials. I love how simple and efficient you explain things. Thank you man.

[appalchandra]

If the video is too l0ng, That's no problem. But without details of each component and all steps, the video is not helpfull.
You are the great. Thank you so much big brother. Love from Bangladesh...🇧🇩

[topnotchgamer]

Excellent tutorial sir, Love from Bagladesh.❤❤❤

[invisiblestudy]

What is use of relay ?
What is output voltage? 2:52

[mertertorer]

Do you know the board configuration for esp 8266 12-e ?

[gopinathkamaraj]

You have used a capacitor in your custom pcb board but have not mentioned it's value can i know the value of the capacitor please. I need it for my project 😢

[silugr]

I am trying to drive a single channel relay with node MCU . I am powering relay and node MCU with different sources. The relay is blinking but the relay click is not happening. Can someone please help me

[rhodiumindia]

New blynk app problem.
Save template in browserand app did not show the template

[akhila]

Code for switch is unavailable
Can you please attach the code required and library in comment section

[reciansanjeev]

Bhai I am unable to code my nodemcu please help me ... During coding it showing Error compilation in Esp 8266

[sureshgurjar]

Yah complete PCB mil sakti hai kya with component

[uhacks]

@Tech StudyCell  sir what do I need to change in sketch to use touch switch using tp223 instead of push button?

[kuroshikurt]

My friend im trying to get the code but still i cannot find it

[meenakshisundaramramanatha]

Nice project sir. Built it as per tutorial.
I am trying to replace push button to HTTM sensor, where I have problem with sensor state when the relays are controlled by blynk. Kindly help me with this.

[Anhad]

Do you have this product all assembelled available please?

[csekeerthiga.v.n.r]

I am getting "BlynkEdgent.h" :No such file directory error message...Any solution?

[jijeshkorothpoyil]

Hai
Can we use the same single nodemcu to work with ifttt and blynk simultaneously in a single program?
Ie;
I need to get telegram call when motion detected in my home and I should be able to control my lights through blynk.
Is it possible?

[rehmanullah]

Sir, I'm having issue, kindly reply me in your previous video of 4 channel relay.

[uhacks]

Sir can you please give code for 4 channel relay for this same project? Waiting for your reply . Soon I have to submit project.

[FZaighumJawadAslam]

bro i have done all the steps clearly but when i press ESP8266 Blynk device buttons that i created which are OFF and ONN two button nothing happens...what could be the issue. it doesnot turn the state of button to ONN . it stays OFF
