- In this IoT based project, I have shown how to make the ESP32 Alexa home automation system using Amazon Echo, IR Remote, and manual switch with the EspAlexa library. You can also scan QR code to enter WiFi Credentials Over the Air using ESP BLE provisioning app.

For this ESP32 project, I have not used any IoT platform. You can control the relay with IR remote, and switches if the ESP32 is not connected to WiFi.
During this IoT tutorial video, I have covered the following topics:
00:59 Quick demo on this ESP32 Alexa home automation system.
02:03 Required Components for Alexa Project.
02:09 Circuit of ESP32 IoT internet of things project.
03:48 PCB for the ESP32 control relays.
04:10 Source Code for ESP32 IoT project with WiFi provisioning.
08:03 Generate QR code for ESP BLE provisioning app.
08:32 Enter WiFi details using ESP BLE provisioning app.
09:27 Add devices in the Amazon Alexa app using ESPAlexa.
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
5. Amazon Echo Dot

Important points for this internet of things projects:
1. The IR receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code.
2. You need an Echo Dot or any other Amazon echo devices for this project.
3. The ESP32 and the echo dot smart speaker should be connected with the same WiFi network.
4. If you face any issue related to Espalexa library, then please visit github.com/Aircoookie/Espalexa
5. to reset or enter the WiFi credentials press the BOOT button for 5 seconds, before scanning please turn on the mobile Bluetooth and GPS.
6. If you face issue with QR code, enter POP and service name in the ESP BLE provisioning app.
7. Use a stable 5V 5A DC power supply.
During the ESP32 project, I explained all the steps to make the Amazon home automation system how to use WiFiProv.h library to update the WiFi credentials through OTA.
Also explained how to add this WiFi provisioning feature to any IoT platform.
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.

Bagus banget luar biasa terimakasih informasinya semoga ilmunya berkah. Salam izin ikut belajar pa..
We are having two channels taking codes from each other and the output is helpful for the diy community I love it
How to connect in switch
I have done many projects of yours successfully But I don't understand why Esp8266 doesn't connect to internet automatically like Esp32 ?
can you please provide code for 8 ch relay
Muy buenos tus videos amigo
Thanks
Can you give me the code for 8 channel relay please
can i make this project with out alexa device ????
Thanks,A great person
Most welcome
Can i use esp8622
Please make a gsm motor starter control using 2 relay START relay and STOP relay (trigger type) relay on only for 5 second via sms and phone calls and status update via sms
Ham umeed krte h ji ki agli ane wali video bt + blynk +manual+ wifi credential ho with fan speed tnx for new video ❤❤❤
Will try
Nice video bro🥰❤️...can you make video on home automation using cadio and using esp 32 chip including c-type connector means inbuild programmer on pcb.
Thanks
Ok I will try
If u have 3 in 1 project Blynk + Bluetooth + IR 8Ch using Esp32 please share the link.
will make
only light one device shows on amazon alexa
Well project ❤❤❤
Thanks
is it preference library possible with ble WiFi provisioning ?
I have tried, but getting error
@@TechStudyCell Dear friend thanks for reply. Same thing happened with me. If you get success please share with your followers. Thanks again.
Dear Friend, Have you got success with preference library if yes, please share, if not please try it out for your subscribers. your reply is keenly awaited. Thanks.
Good work. I need help on a project
How can I help you?
Please make a echo device...like Amazon alaxa 😊
You need raspberry pi
Ir ki jagha rf ko q nahi add karte?
Will try
Sir main ummid karta hu blt+blynk+manual hoga
Will try
@@TechStudyCell Thanks Sir thanks 🙏🙏🙏🙏🙏
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.😊
can't discover devices on alexa.
Esp rainmaker get disconnected (ESP rainmaker offline can't connect again with re-pairing if you want again then u have to erase flash memory and program it again to make it online and same problem persist after some days )after some days and you can operate devices manually only ,no automation is there due to out of budget on esp platform,worst platform for iot please give any solution on that.please sir. Must reply
Otherwise esp rainmaker best
If are sending any sensor data, please send it after 20 second interval
@@TechStudyCell i am using your code as it is please can you tell how we can edit and in which portion we have to edit. Also i am wants to remove DHT11, sensor portio from schematic if possible please cam you help me?
Sir please can you tell how and where i can change interval because as use your same code then you also facing the out of budget error(reconnecting issue) so please make short video on editing existing code such as change interval time. Please must reply 🙏🙏 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
If you help me u will save me sir.....❤ because with esp rainmaker your project (4 devices with fan dimmer+ir+manual+alexa) was very superb
download the code again... and try
How can i contact you
sir plese help me. this video ruclips.net/video/vBq3Ozrwj-4/видео.htmlsi=fUY5WAGt2Xip-VYM
