ESP32 Home automation with Google Assistant Alexa & Manual Switches - Internet of Things 2021

In this Internet of Things project, I have shown you how to make ESP32 Home automation 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.

Visit the following website to get electronics components, modules at a very reasonable price

During the tutorial video, I have covered the following topics:
00:30 Control appliances with Google Assistant and Alexa using ESP32
00:56 Control appliances manually with switches.
01:25 Required Components for this ESP32 project.
01:48 Circuit diagram of ESP32 home automation project.
02:48 How to create and configure Sinric Pro account.
04:14 Program ESP32 with Arduino IDE
06:25 Setup Google Home App to control ESP32 with Google Assistant.
07:35 Setup Amazon Alexa App to add IoT devices.
08:37 Control relays with voice using Google Assistant

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

NodeMCU Home Automation with Google Home & Alexa

**With this IoT project I can control all 4 relays manually with switches. But as I have used the free Sinric Pro account, so I can control 3 devices with Google Assistant and Alexa. To control the fourth device, you have to purchase 1 device in Sinric Pro.

**You don't need any Alexa devices like Echo Dot or Google Home Mini. You can just use Google Home App and Amazon Alexa App for this smart home system.

**If the ESP32 is not connected with Wi-Fi, then you may face some delay while controlling the relays from switches.

Download Code for this ESP32 smart house automation project from the following article.

During the internet of things tutorial video, I have explained all the steps to make this ESP32 home automation system with Sinric Pro to control the home appliances with Wi-Fi. I have made this Google Assistant control smart home system without IFTTT. If the ESP32 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.

⚠ This video took a long time to make if you would like to buy me a coffee to say thanks, link below: ☕

[ronniepirtlejr]

You are making my Google Mini nest egg speaker go crazy every time you say "hey Google turn on light" it keeps saying " I'm sorry the lights have not been setup yet!" Lol

[gauravganguly]

The best part is, one always gets to know something new !!! Great work 👍👍

[gungunmaurya]

Best of the best video ever but don't you think there should be an Android app so we can control this system even when we are offline

[mayankgoyal]

Great videos sir. Can it be done only with alexa/google home app without 3rd party apps like sinric, blynk

[TechnicalMech]

thanks so much sir, i made this project and it is successful .but there is a little problem, the first one is when i say turn on light on google it take more time approximately 6 to 7 second, and on alexa it takes 3 to 4 second or more, and the second problem is that the 2 relay is operating with voice command on google home but the one is not working, the three relay working on google home button but not work one of these relay on voice command of google .and in alexa app, the three relay work on button and also work with voice command, plz replay

[rameshniroj]

Awesome Work,
Please Add GOOGLE ASSISTANCE + BLINK APP TO 8 RELAY MODULE
PLEASE SIR ❤️ 🙏🙏🙏

[muslimkafa]

12v relay is required for big room 5v is smal if your wire is long

[shrikantnikam]

Kya hum logic devlope kar sakte hai kya arduino ide jaisa?

[mridupabansharma]

Which is best for home automation system esp 32 or 82

[koteswararaoneelapu]

Superb sir.... please tell me how to operate 8 channel

[buddydip]

Sinric pro has lot of issues with frequent disconnections and chargable if more than 3 devices are used. I used it for sometime and switched to OpenHAB which is completely free and having lot of features and very easy to setup. Also do you think it is better to connect to the internet directly from the nodeMCU/ESP32 or use a local broker like Mosquitto and edge platform to control all local devices?

[nikkmer]

Awesome video tutorial. One question, how can I use this to start my business and sell it professionally ?

[RizalAmri]

Haii, awesome video you got here 🙏🏻💯
I also watch your other video, and i got some question, so there's no difference using custom board and normal installation expect the more clean installation from using costum board, is correct 🤔? Even though you already said on some videos no need custom board 😂🙏🏻, just make sure 👌🏻

[lpjakarta]

hi what if it is over 4 lamps, does the relay need to be replaced by using, for example, 8/12 lamps?, thanks a lot for your answer.

[getthegeet]

Can you use smart living or tunya instead of sinric or bylnk?

[jaydmatacarita]

Your video description is misleading. It should say:
Google Assistant - Sinric Pro - Esp32
Sinric Pro is $3 per device and they store your data.

[naveenkp]

I am most expected program this.
Thank you.

[kiranm]

Quick question, you have used actual switches instead of push button. I understand the mechanical switch will have its own resistance. Won't this lead into an issue? Did you face any issue on the same?

[hasratali]

Hello sir
Sar light jakar jab aati hai
Relay usi condition mein hoti hai Jo light Jane se pahle thi
Yah change ho jaati hai
