IoT based projects using ESP32 Alexa Home Automation | Enter WiFi Credentials Over the Air
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 https://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.
