For this ESP32 project, I have not used any IoT platform, and the ESP32 can save the last GPIO state in NVS flash memory (EEPROM). You can control the relay with Bluetooth, IR remote, and switches if the ESP32 is not connected to WiFi.
During this IoT tutorial video, I have covered the following topics:
00:44 Quick demo on this ESP32 Alexa Project.
02:36 Required Components for Alexa home automation system.
02:46 Circuit of ESP32 IoT internet of things project.
04:35 PCB for the ESP32 control relay with fan dimmer.
05:17 Source Code for ESP32 IoT project with ESPAlexa.
06:35 Add devices in the Amazon Alexa app using ESPAlexa.
07:37 Connect ESP32 with Bluetooth app.
09:06 Install the IoT-based ESP32 home automation system.
Required Components (without PCB) for the ESP32 project.
1. ESP32 DEV KIT V1
2. 8-channel 5V SPDT Relay Module
3. TSOP1838 IR receiver (with metallic casing)
4. HC-05 Bluetooth module.

Steps to program ESP32 with Arduino IDE: • Programming NodeMCU ES...
Important points:
1. In the 4-step regulator step-2 & 3 must be internally connected.
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 fan speed 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. You must need an Amazon Echo device for this ESP32 Alexa project.
7. The Amazon Echo device, ESP32 must be connected to the same WiFi.
8. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.
During the ESP32 project, I explained all the steps to make the Amazon home automation system. For Bluetooth control, you can use any BLE or Bluetooth module.
With this ESP32 home automation project, you can control the fan speed and relays without WiFi from the Bluetooth, IR remote, and manual switches.
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.

This video should have at least 500.000 views. It explains multiple things about automatication and gives you a pretty good view on the object of smart home. Thank you man. You are very useful!
Local Danish authorities will run screaming away from this wire setup , yelling possible fire 🙂 Nice video by the way.
Hola. Muy buen proyecto. Saludos.
like the features, setup was difficult for some of my devices (August Door lock, ua-cam.com/users/postUgkxhB5YOMNj04GuoAosExygP4cH-dKeb4aB Bose speaker)... but all switches and outlets (5), thermostat, tankless water heater. Unfortunately all I can do is turn on/off Bose. It doesn't support volume or changing channels, but I believe that is due to the particular speaker I have.... Worth getting if you already have other devices to use it with... I don't sit around and ask Alexa questions much so that doesn't really matter to me....
Hey I wanted to ask why u haven't utilized the 8th channel of the 8 channel relay board, and if we do wish to put it to use can we still do so using the ESP32 as to add on another load and control it, please let me know
I've got a doubt with manual fan regulator
Actually since there is no vcc connected to it, how will the board sense the signal from the regulator?
Really very nice, I appreciate and learned a lot. I tried in my home, working fantastic but without using Bluetooth. One more request, can you please add matter protocol in this lovely tutorial. Overall you are my great teacher. I hope, you bring such a valued IOT projects in future. Please reply I will be very grateful to you. Thanks
Hello TechStudyCell! Relay no.8 is vacant anyways, can we utilise it by adding a device to it? Please let me know your thoughts. Thanks😐
wow I am thinking about upgrading my telescope tracking system with an esp32 or an orange pi 5. What would great is to talk the the scope on a long dark starry night? 😎 thank you.
Why don't you use inbuilt Bluetooth instead of hc05??
Can you also define and send serial commands with this?
If I connect 2 set-up in one device
Like hall and room
Can u explain how to connect two ESP 32 in one device
I love you so much sir
Nice Video 👍
Thanks
Hello bro.. please provide the link..in which i buy the 4step rotary switch fan regulator.. please brother
I had made one with your guidance but while i tap the manual switch relays continuously gets on off like the LED blinks ....what is the solution for this let me knoe in the comment
Please make a same project like this but with an additional relay which can handle high end appliance like air conditioner

I want to use Google Voice Assistant with Node MCU. without External App like Blynk, Sinic Pro, IFTTT, etc. I want to use Node.js and connect? Did you make any such videos. I tried using google assistant api in google cloud with blaze subscription as well. I am getting errors. Do we need really Rasberry PI for this?
Can we add multiple esp32 in this?
During flasing node mc it showa flash size is grater than esp32 memory please help
Wowww
Can we do this with esp8286
Can i use Arduino uno instead
Please also make integration your device with home assistant.
Esp32 has inbuilt blutooth and wifi module then why spending extra money on BT module?
BOM file and CPL file is missing..please upload the file for further
sir,I upload the code but in alexa app the devies are finding
What is the cost of PCB can we purchase only PCB from you
Hii, I have built this same project with the help of this video, however, my ESP32 is not the same. I bought "NODMCU ESP32S" which has 38 pins. Everything is perfectly working except Bluetooth, as the TX and RX pins are different. Could you please help in resolving this issue?
Thanks
Yes; I got it working. instead of using Tx and Rx pins, I have used Pin number 16 & 17.

@@firdoshdiakus4841 How ??
@@firdoshdiakus4841 Can you share ??
Superb bro, can we use it from anywhere like using it with ESP Rainmaker?
yes... but echo and esp32 must be connected with same wifi
@@TechStudyCell hi there i really loved the tutorial will make one for my home.i just have a question
Can i use esp32-cam in this project
Can we use push button please reply sirji..plz if not then plz can u provide a code for that.....pleaseeeeeeeeeee
ULN2003 instead of all the transistors and optocouplers to control the relays might save a lot of space. 🤔
ULN will not provide required isolation.
For space saving we can use smd components.
Multi channel opto isolator smd package is also there. 🤔
@@Crystalservices Do we must need the optocouplers? ULN2003 can directly pull down the relays inputs. Cant it?
@@GourabX Yes, but if we need isolation from noise generated by relays then it's required.
@@Crystalservices Yes I totally agree. And I chose to ignore that problem. 😂😂
Bro explain code(program)
Want to by this
Hi sir,do u teach also?
Iska setting kaise kiya jata hai
Hi, can I use echo dot 4 with esp32?

@@TechStudyCell does espalexa library works without an Amazon Alexa Speaker...? Actually I don't need the voice assistant but need to connect multiple ESP32 Boards, Is it possible to control the devices only with Alexa Mobile Application..? Please can you check this for me, i mean if I upload the basic espalexa code will the Alexa Mobile Application Discover the ESP32 boards... ?
Please reply
Queries??? Sorry I missed
@@TechStudyCell i have seen all your videos but did not find any video where you have used relay which can support high end appliance like air conditioner. Please suggest if these relays can support AC?
