Best ESP32 project with Alexa Google Home Automation using ESP RainMaker - IoT Projects 2022

In this IoT project, I have explained how to make an ESP32 project with Alexa, and Google Home Automation using ESP RainMaker to control relays with voice commands, IR, and manual switches and store the last state in ESP32 flash memory (EEPROM). I have used all the free tools for this IoT-based smart home system.

During the ESP Rainmaker tutorial video, I covered the following topics:
00:27 Quick demo for the ESP32 IoT Project using ESP RainMaker.
02:41 How to use Preferences library to save data in ESP32 NVS memory
04:17 Example sketch to save the last GPIO state in ESP32.
06:31 Required components for ESP32 project.
06:38 Circuit diagram of ESP32 home automation project.
07:12 Source codes for the ESP32 IoT Project.
10:20 Add device in ESP RainMaker app.

Required Components for the ESP32 internet of things project.
1. ESP32 Devkit V1.
2. 8-channel 5V SPDT Relay Module.
3. TSOP1838 IR receiver (with metallic casing)
4. Switches or Push Buttons.

Important points:
1. You don't need any Amazon echo device for this IoT Project.
2. You need to install ESP Rainmaker, Google Home, and Amazon Alexa IoT applications on mobile.
3. You don't need to install Preferences.h separately.
4. You can control relays from any WiFi network.
5. Update the Preference URLs to install the ESP32 board version 2.0.3.
6. To reset the WiFi details, press and hold the ESP32 BOOT button for 4 seconds then scan the QR code.
7. IR receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code.
8. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.

During this ESP32 IoT tutorial video, I explained all the steps to use the Preferences library to save data permanently in ESP32 NVS flash memory.
In this ESP32 project, you can control the relays without internet from the IR remote & switches. ESP32 will automatically connect with the IoT cloud when the internet comes back.

If the ESP32 is connected with Wi-Fi, then you can control the relays from anywhere in the world with Alexa and Google Assistant. And you can also monitor the real-time feedback on Amazon Alexa, and Google Home app. So with this IoT project, you can convert any appliance to IoT devices and control them through the internet.

So, now you can just ask Google Assistant, "Hey Google, turn off lights", or "Alexa, turn on light". that's it.

This is really awesome, useful and a new learning for me.

I have implemented this logic for my tomorrow’s video right now is last moment but it was worth it!!!

Thanks once again ✌🏻

[victorultimate]

Actually implemented this project following this video guide. It was fun and interesting.

[Romiqtiink]

wow what a brilliant and inspiring idea. if you add a motor to the curtain it will definitely be more interesting.

[khatrichaitanya]

your skill absoluto fine and amazing with new trend, your coding skill very high but project somehow not practical due to some minor bugs or improvement needed

when esp reboot any reason it will connect wifi

but any reason wifi hotspot restart not connect to wifi .why?

it is not practical to each time reboot esp module,

this problem not only me but many user in your subscriber,
kindly look this matter

with out support making new project not possible,
kindly do some little help to me
kindly update and upload same code with auto reconnect feature .


i hope you understand my concern

[khanlalamemes]

Is it possible to use ESP 8266 instead of ESP 32? kindly explain it.

[iamrafic]

Much waited project, thanks bro. Keep up the good work.

[SabirHussain-yyzi]

Hy sir my ir remote is not working??? How to solve this problem???

[ashishsbhavsar]

It's not reconnect automatically to wifi when router restart, have to press button or restart the esp32 module to reconnect to wifi
Except this error the Project is Amazing as I'm using this from last 8 months in my home.

Please provide solution for auto reconnect.

[allenhiyas]

this project is so great!... can you make this project with ethernet port (w5500 lan module) i want to connect this to my internet thru cable... thanks...

[novajaboticabal]

Great
Could you make a video teaching how to make a thermostat with rainmaker on esp32 and DHT22.
I'm counting on your help.
thank you in advance

[rabeeusman]

my esp32 not connecting to wiffi automatically after went offline please guide me to resolve this issue

[manojnathaneal.s]

Bro please make a video for fire detection and alarm system using blynk 2.0 app bro... That will be much useful

[biswajitcreativity]

When the wifi signal is lost and come back wifi signal the ESP 32 not connect automatically in the wifi .
And I turn off and on ESP 32 then the network connect.
Not automatically connected why sir

[rohanramachandra]

Hello sir! Can you tell us how much size this code consumes to help us select the right ESP 4M or 8M...
Also can you tell us how to interface a 2 way switch into this logic.

[markinesisetc.]

Why not connected to my wifi?only visible but not it cant connect

[drelectronics]

As now we have best home automation pls make next video on ota update with rainmaker it is possible and shown on their web

[albinbiju]

Thank u so much😃 broo can i use water pump it is overload device in same project

[koteswararaoneelapu]

Superb working sir cod
Sir, how many board working this code

[gingin-eh]

Compile windows7 not work how to fixed?
Windows 10 work
