ESP32 Home Automation using Amazon Alexa + Bluetooth + IR Remote with FREE IoT platform

In this IoT internet of things project, I have shown how to make the ESP32 home automation system using Amazon Alexa, Bluetooth, IR Remote, and manual switch with the EspAlexa library (Free IoT platform). You can also control relays with voice commands and monitor the real-time feedback in the Amazon Alexa app.

For this ESP32 project, I have not used any IoT platform, and the ESP32 can save the last GPIO state in NVS flash memory using Preference library (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:
00:35 Quick demo on this ESP32 Alexa Project.
02:59 Circuit of ESP32 home automation system.
03:28 Source Code for ESP32 project using ESPAlexa.
05:53 Add devices in the Amazon Alexa app using Echo Dot.
06:42 Steps to connect ESP32 with Bluetooth app.

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:
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. 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 other Bluetooth app, just modify the code as shown in the tutorial video.

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.

With this ESP32 home automation project, you can control relays without WiFi from the Bluetooth, IR remote, and manual switches.

This smart ESP32 relay module PCB can be used for different ESP32 projects which I will cover in upcoming videos.

Iam watching your videos in Kerala 🎉🎉 thank you sir

[norules]

Sir provide the step for using shift register I am using 74hc595 & 74hc165.. how to integrate that

[mewedward]

If it esp32 hang or repair means, how you activate swich? Try to solve that also, using 2 way swich like this

[VancedUtube-bo]

I followed ur process but alexa is not recognising the devices while while adding what might be the reason ?

[AsadAli-mzou]

Great, please make a video of Nodmcu8266 using Blynk +IR with 8 channels then disconnect the power supply of Router and Nodemcu 8266 together then Show us how Nodemcu will connect to Router automatically everytime...

[yogendrajamsariya]

I think you should add fan dimmer also

[Eckmuhl]

Is that working with the Fire Stick or Google devices?

[Scroll_pedia]

Thank you brother i ve installed same device for my room after watching your previous videos

[harshverma_i]

Hello sir... please provide the link of 4step fan regulator rotary switch that you are also used in yours project.. please sir...

[pqrst]

Is this the same for the 8 relay project too???

[qadeer]

Welcome sir ❤❤❤

Good job 👏👏👍👍👏👍

Excellent 👌👍👍👍

Very nice project❤❤

[MrSk]

I tried this project but i can't find devices to connect in alexa app please can you give me a solution?

[HarbansSingh-cetm]

Good video bro ❤❤❤❤❤First like ESP32 -S3 Devkit C1 -N32R8V Module use nexte projects pleases

[WawanSetiawan_]

Sukses selalu terimakasih semoga Ilmunya membawa berkah Pa. Amiin .
Salam Kami dari Indonesia mohon izin ikut nyimak videonya.

[canisklanadam]

Very nice vide... sir please http and mit ap inventer example project

[gi_ke_films]

I HAVE A QUESTION if in alexa mobile app its is connect to mobile network not on wifi then it will work like from anywhere in the world

[_green]

Sir pls make video on 12 channel relay having temperature sensor, ldr, ir reciever . Control from esp rainmaker, google assistant... plsss siirrr

[triwahyudi]

Great tutorial.. I am new subscriber your channel, Sir can you next show me video about wifi manager in 8266 ? Thanks Sir

[mayukhbari]

One thing I don't get if the light is switched off from app or alexa but physical switch is in on state. Then how these light will turn on again only by physical switch

[Voice.Of.Nation]

any esp32 home automation with Ac fan speed control?
