IoT Project using ESP RainMaker with Google Assistant Alexa & Manual Switch - ESP32 Projects 2022

In this ESP32 project, I have shown you how to make IoT Project using ESP RainMaker with Google Assistant Alexa to control relays with voice commands and manual switches. I have used all the free tools for this IoT-based home automation system.

During the ESP Rainmaker tutorial video, I covered the following topics:
01:40 Control relays with Google Assistant and Alexa using ESP32
03:03 Control appliances manually with switches.
04:34 Required Components for this IoT project.
04:49 Circuit diagram of ESP32 home automation project.
05:44 Source codes for the ESP Rainmaker Project.
07:38 Program ESP32 with Arduino IDE
08:02 Update WiFi details through OTA with ESP Rainmaker.
09:24 Connect Amazon Alexa with the ESP Rainmaker app.
10:08 Connect Google Home with the ESP Rainmaker app.

Required Components for the ESP32 home automation system
1. ESP32 Devkit.
2. 4-channel or 8-channel 5V SPDT Relay Module.
3. Switches or Push Buttons.

Download the Code for ESP32 IoT project with ESP Rainmaker from the following article:

Download PCB Gerber File of ESP32 control 8 relays:

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 application on mobile.
3. You can control relays from any WiFi network if ESP32 is connected to WiFi.
4. Update the Preference URLs to install the ESP32 board version 2.0.3 as shown in the video.
5. To generate the QR code, press and hold the ESP32 BOOT button for 4 seconds.
6. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.

During the internet of things tutorial video, I explained all the steps to make this IoT-based home automation system, and how to connect Rainmaker with Google Assistant and Amazon Alexa app.
In this ESP32 project, you can control the relays without internet from the manual 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 in the Amazon Alexa and Google Home IoT applications. So with this smart house 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.

I did it and it's working fine....I used the vin pin from esp to supply power to Relay module and used a 5v 1amp charger adapter to power up the esp...

[prajwalhn]

Was exactly waiting for this!! Thank you!

[shijilt]

It works really well. Thank you for the code.
added OLED display to show status of 8 relay and WiFi connectivity, it works really well.
Unlike Blynk Rainmaker is really good. Blynk used to cause lots of issues if offline.

[erustuscheruiyot]

I thank you for this. Three days on the wait. Thank you and following every detail.

[duynguyen]

Thank you very much for my first step of making diy smart home.
Respect!

[shandradm]

1.thank you working
2.not working with server without internet
3.how i change relay state for last state?

[aravindhanvivekanandhan]

thank u man last video i mention comments do rainmaker project now u done You are great
can u add more sensor related to home like door sensor security alram, motion sensor

[pqrst]

I tried this project and it really work and I'm really happy from it thank you for this video i just have 1 issue with this project is that when ever esp32 restart it sets all the relays to off mode. Is there any way to make it remember which relay was on and which was off . Please reply

[Maii.c]

Hi! Nice video, could you teach how to conect two Relays and a stepper motor (or cc motor) to open, close (or set height with percentages) a roller blind?

[contalivreemaberto]

Excellent very educational video.
Could you please make another one with the thermostat function.
With DS18B20 and also with DHT11
I thank you in advance

[luisenriquehernandezzamora]

thanks for the amazing but i have a question in case i don't have an ESP32 board, can i use an ESP8266 instead?

[IoT-InternetDasCoisas]

Perfect, complete and detailed video tutorial, I made it here and it worked correctly, please, can you make a Tutotial like this, with ESP Rainmaker and MQTT together?
Congratulations on the video and the channel!"

[Garagebd.]

Sir the project is very nice please add 3rd speed fan dimmer to it

[paulhowes]

Great project. I got this working no problem. Is it possible to have 2 of these on the same network and within rainmaker? What needs to be changed in the code to make each esp32 unique.

Many thanks

[kamalkamel]

Thank you very much for all the work you have done and shared. well done my friend

[sunfoundermakereducation]

The very practical project, thank you very much.

[iuhere]

nice video, only issue is that once net is down it becomes useless for any remote control mechanism, basically it becomes a dead switch just like our non smart regular home switches, at lease if the wifi is available irrespective of internet, then we should be allowed to locally use the controls, lik esphome or homeassistant or even tasmota, or esp purna, but rainmaker becomes uselss once you are without internet. This was only limitation otherwise it is very good overall.

[ravirajkala]

I have been an ardent follower of your videos and have constructed most of your circuits. In this one, is there any way to remember the last state of relay before power cut?

[muhammadnor]

I really like this project, thank you sir.

[pnfactinfo]

Very nice project & detail explanation. Please make a project using RainMaker with fan speed controller.
