For this ESP32 project, I have used the FREE plan of the Blynk IoT platform and I have not used any external Bluetooth module. The ESP32 can also save the last GPIO states in NVS flash memory (EEPROM).
During this IoT tutorial video, I have covered the following topics:
00:09 Quick demo on the ESP32 IoT Project with Bluetooth.
02:38 Circuit of ESP32 IoT-based home automation system.
03:13 Setup Blynk IoT cloud for the ESP32 project.
04:19 Source Code for the ESP32 Bluetooth project.
06:01 Set up Blynk IoT app Mobile Dashboard.
06:39 Connect Bluetooth app with ESP32.
Required Components (without PCB) for the ESP32 project.
1. ESP32 DEV KIT V1
2. 4-channel 5V SPDT Relay Module
3. TSOP1838 IR receiver (with metallic casing)
4. Switches

Important Links:
New Blynk IoT Cloud: blynk.cloud/dashboard/register
Important points:
1. The Bluetooth app need "Nearby Devices" permission in your mobile.
2. IR receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code.
3. ESP32 can save the last GPIO state after power failure.
4. You can control relays with Bluetooth, switches & IR remote if WiFi is not available.
5. Install the correct version of the ESP32 board and libraries as mentioned in the code.
6. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.
During this Blynk tutorial video, I explained how to create a home automation system step by step. The cool thing is, you don't need any extra Bluetooth gadgets for controlling things through Bluetooth.
You can also add Blynk Automations to control the relays with the pre-defined timer.
With this ESP32 home automation project, you can control the relays without WiFi from the Bluetooth app, IR remote, and manual switches. ESP32 will automatically reconnect with the Blynk cloud when the internet comes back and the relays will turn on as per the previous states.
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 ESP32 smart relay module PCB can be used for different ESP32 projects which I will cover in upcoming videos.

Thanks brother you are teaching us without forcing us to pay or something else its very hard to find people like you
Lots of love from Nepal 🇳🇵
Hi brother
Excelente aporte. Gracias!
You are great sir ❤❤❤❤
Great,a very nice person
Have you used eeprom memory to store relay status....
Sir I'm using active High Relay Module, pls tell me in which part shuld I modify for the active High relay
Is it possible to use it from anywhere in the world along with the voice commands and manual switches or the app? If possible, then please suggest how to do that.....
Good job bro......... Please make 16 channel same project .
🤩🤩🤩nice video bro..... thanks for sharing......
Thank you too
Thanks sir..
Welcome
Thanks for sharing. I think, it is better to use EspAlexa library 2.7.0 as this is free instead of Blynk ( chargeable). I request please make a project. Second I think you are the best and very sincere to your job that’s why I request you to start a series on Home Assistant. This is truly addition knowledge for your subscribers. Thank you very much my friend.
Thanks for the feedback
Make a Super project with esp32 with these features(in 8 channel relay):
1. IR remote control
2. Bluetooth/wifi
3. Preferences.h
4. Touch sensor switch
5. Add other features which can be added
What is the difference of using built in bluetooth of esp32 and external bluetooth module? I think if we use built in, we can connect one device at a time and if we use external bluetooth module, at least 7 or 8 devices at the same time. Am I right?
with Nodemcu project if power of router and Nodemcu goes off 5 or 10 times in a day in this case Nodemcu will not connect to wifi automatically in this way all projects with Nodemcu are useless.This is due coding or due to manufacturing fault?Please guide me
Super and u r one more help Bluetooth mesh and WiFi mesh send one video
I admire your content and expertise. Could you please consider creating a brief video on using an ESP32 with Apple HomeKit? Your guidance would mean a lot to us.😊
I don't have any Apple device. May be in future
While turning on the fourth switch ESP got reset what to do pls tell me
👍👍👍
can we control this automation using Alexa or google assistant?
Sir, could you please consider making a tutorial/video to control these relays instead with the raspberry pi but using the Arduino Iot Cloud and the API they provide for the mqqt broquer exchange
Bhaiya mera project only wifi connected he ushke liye muje kon sa code dalna padega please bta dijiye ....project name home automation using node MCU esp32
Hello sir, I greatly admire your incredible work. is it possible to see the source code block for bluetooth app please? thanks ❤️
Wait. Will upload in article
Dali control system in wifi system pls tell me
I made one of your projects with NodeMcu using it works well but if power goes off then Nodemcu will not connect to wifi automatically then the project is useless 😢
Can i use this code with esp8266
Please tutorial using module SIM800L without wifi,
not all places have wifi.
Sir, If we switched ON through mobile then is it possible to switch off by manual switch?
Yes
Sir i don't want to use ir remote. In that case can I use this code
You don't have to do any changes in the code. You can use same code
Sir please add 1fan Regulators in this project
Esp8266 in Dali light control system in online and blutooth and WiFi how to control in 64 light
Plse sir add 1 fan speed with this project without using HC-05 bt module
Dali control system in blutooth system

how to fix it???🙏🙏🙏
Same problem my project how to solve ❤
Use it Alexa app connect and not use blink app .
You use blink app , we can not connecting to Alexa.
Please help and make it❤❤❤❤
Blynk and pzem
Hlo sir ye problem kaise solve kare

Same problem
@@v_3farmaviary870aap ka problem solve hu ki nahi
Bro make it 8 channel
Please make a home Automation with Arduino and sim800l GSM module
But my esp32 dead 😢😢😢 I don't have money to buy new
How to do without blynk because it is premium
Please make 8 / 10 channel relay control of the same project ❤
All are good but we are not connect to Alexa 😭😞😭
Will make video on ESPAlexa
Thanks 🙏
@@TechStudyCell plz add IR sensor and timer also in Blynk app ua-cam.com/video/CpUVssHPm_s/v-deo.htmlfeature=shared
I hope you understand.
Plz reply
sir please make 16 channel, ir remote, google assistent and not use manual switch
