IFTTT sign up: ifttt.com/join
Important points:
1. You can turn ON/OFF the automation anytime from the Blynk IoT app.
2. IR receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code.
3. The Blynk Automation will not work if the ESP32 is not connected to WiFi
4. You can control relays with switches & IR remote if WiFi is not available.
5. Install the correct version of the ESP32 board and libraries as mentioned in the code.
7. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.

During the tutorial video, I explained all the steps to make this IoT-based home automation system, and how to set up automation in the Blynk IoT platform.
In this ESP32 project, you can control the relays without internet from the IR remote and manual switches. ESP32 will automatically connect with the Blynk cloud when the internet comes back.
You can use any IR remote to control the relays, just get the HEX codes of unused IR remote buttons, and control the appliances with those buttons.
This smart relay module PCB can be used for different ESP32 projects which I will cover in upcoming videos.

your work is awesome and wonder.by doing your project in my colleage . i got 4 th place and i recieve many wonderfull wishes from staff and student's .this is becoz of u
Looks fab, all nice and neat, no ugly wires dangling about all over the place......i'm gonna throw away all my Philips hue bulbs and do this instead.....my wife's gonna love it
I just implemented this project following this great and carefully guided tutorial. Thanks a million.
You are welcome
It is very usefull project and i have been seen other your projects that's are also amazing and very usefull
Amazing project, thank you for sharing. Could you do a voice control of an analog signal, like controlling a servomotor position with google assistant?
Perfect and very very nice bro
very nice but some off us would like to redesign the pcb according to our switch board and wall outlet.... please do share the schematic and not just the gerber file
Very professional work, Thanks my friend ♥️♥️♥️♥️
Thank you too
thanks for ur video , i have made some changes to use 8 relay , im getting error ""pin 5 not included in the scope " kindly advice
Good job bro
can you please do ESP32 PCB design with 16 relays, IR, BL and wifi control, including 5V regulator. Basically only one ac in, and 16 switch control out. Controllable by IR,BL and wifi
Very well managed project on suggestion to add dc voltage and current measure as now a days all the home appliances are operated on dc voltage so on can monitor completely and some flaws are there in project when no internet is available for long device get hanged no control over push button as well as remote so we need to restart the device plz make this fix with updated virtual pins for voltage and current ...
can we increase the number of relays in this particular arrangement?
Sir
Can we control fan speed with home automatic system
What is the alternative of IR sensor?
Can we use 220v switch?
Can u do the same with esp8266, and cadio app
What I mean is, is it possible to make 4 channel relay and also universal ir remote using esp8266?
Sir may you start playlist for IoT home automation. I want to teach from you
@Tech StudyCell Bro, i just want to know that how NodeMCU will get signal abt the real time status of bulb whether its ON/OFF , Which Sensor u have used to know the Real time status of Bulb, fan, etc....
Nice Project Sir, Can u provide the link of the Design Files
Sir, I have 1 question. I have connected AI Thinker ESP32S module to 16 Channel Relay module.
It is low trigger relay. So when I run the blink program of Esp32 ( No Arduino .Only Esp32 and relay module), using Arduino IDE, Relay should turn ON at Low and turn OFF at High. This action should repeat continuously.
But the problem is When I connect relay pin to esp32 D2 pin, the relay is turned ON and always stays in ON condition. No OFF action happens.
Please provide solution.
Bro I'm making this project If,I will face any problem than I can ask you.
Thanks for the nice project ☺️
Спасибо👍

Bro I made a 6 channel home automation project for my college after watching your video.
🟢 Now I want to make another home automation project using 8 channels instead of 4 channels like this video, which will include google assistant control, 8 channel relay, temperature monitoring, IR remote control, manual control, blink app.
🙏🙏🙏 Please, please, please make a video like this.💝💝💝
Please check last video on our TH-cam channel
how to enable exposure to automation option it's not visible on our end
very nice and useful project, very well and clearly explained - thank you for your great job :) I have a question regarding your sketch - what is "fetch_blynk_state" used for ? its value is always 'true'
Please watch the complete video. If the variable is true, whenever ESP32 connect with Blynk, it will fetch the state from Blynk cloud.
cloud we add an Arduino code when i press a button (ex:pin 5) for 10 seconds break the current process and create an access point to input WiFi-ssid and password and blynk authentication code then reconnect to wifi
in-case i changed the WiFi credential
Sir i have some questions... Can i contact with you
Can I do this using ESP8266?
Bro please design a pcb for this to use directly on AC supply 220volts without 5v additional power supply
what is there is no internet or if the wifi is off ?
Thanks for video.Can you show us how to connect lora Ebyte e22 or e32 or sx1276/78 with esp32 or esp8266 to control relays?
Okay noted.... Thanks
Hlo sir I had a esp8266, would this code will for it
Great project
Thanks
Sir, pls uploade a vedio of home automation, it consists 16 Chanel relay, each realay control manually + IR+ BLINK
Wahooooooo
Excellent 100 times
Love you my brother
Love from Saudi Arabia
Thank you so much 😀
Very useful project 👍
Thanks
Perfect
Thanks
Can timer work when no internet ?
my esp32 board is not reconnecting after lost wifii connection plz guide me to solve this issue
Very advance. Sir can you add 8 Relay This project. and Can you Remove IR remote option
Great project sir thank you for this project
Sir can you please help?
Please can you make a same project but the on and off timer is in minutes format means 5 min on 5 min off and this will going in loop upto set time in hrs eg.6hr after
6hr the remaining 18hr timer will of and then again on for 6hr in loop 5min on 5min off
Bro, can you update this project to use only code with remote.
Hello sir, Pleas make a video with esp ch340
Excellent work excellent explanation all flavors are available. Can you please add eeprom and dimmer then it will be complete home applicable automation ?
Thanks. I have started working on it. But this may take some time.
It doesn’t work the ir controller why?
how much did it cost in total for developing this projectt??
👍
Super video
Nice video sir 👍👍👍
Thanks and welcome
Single pulse like a push button I mean that latching in sonoff like
After about 30-1 hours NodeMCU8266 wifi is disconnected. Without restarting the module, wifi is not being connected and apps are not working. What is the solution to this problem?
The function decode(&results)) is deprecated and may not work as expected! Just use decode() without a parameter and IrReceiver.decodedIRData. . i face this issue plz tell me
Yes I have also same problem😮💨. Are u finded solution for this
Bro..... I appriciate your work but i need your help. I have to sumbit my project in collage of home automation using esp32 wifi+bluetooth+ir + temprature+manual. So could you provide me this same code with updated version using Bluetooth 🙏🙏🙏
It is hard to add blutooth + wifi in same microcontroller
J'aime bien vos projets alors faites aussi des vidéos en Français pour nous qui parlons uniquement que le français
❤❤❤
Sir please replace GOOGLE Assistant with ALEXA and make a video
Hello Techstudycell, I have been following your videos and I have made some of your IoT automations. I appreciate you for all these nice videos.
In the codes for this automation (Both Latch and Button codes), when compiling the code, I received an error message about "BlynkTimer timer;" function, In the error message, I saw "Conflicting declaration BlynkTimer timer" please How can I solve this? Thanks.

Sir es code ko ESP8266 m upload krne ke liye kya changes krne honge?
Video on esp8266 will publish tomorrow
Thank you for the great video, i think automation option is not avilable for free Blynk users
I have used free plan. may be they have changed the policy
Can i try this code on esp8266 module ???
Its working fine
My brother, how much you paid for PCB?
