ESP8266 NodeMCU Home automation with Google Assistant using Arduino IoT Cloud

In this IoT project, I have shown, how to make ESP8266 NodeMCU Home automation with Google Assistant using Arduino IoT Cloud IoT platform.

Here I have used Altium PCB Designer to make the PCB...

3. PC817 Optocuplors (4 no)
4. 510-ohm 0.25-watt Resistor (4 no) (R1 -- R4)
5. 1k 0.25-watt Resistors (5 no) (R5 -- R9)
6. LED 5-mm (5 no)
7. 1N4007 Diodes (4 no) (D1 -- D4)
8. Push Buttons (4 no)
9. Terminal Connectors
10. 5V DC supply

During the Arduino IoT cloud tutorial video, I have explained all the steps to make this ESP8266 smart home system with Arduino IoT Cloud to control the home appliances with and without the internet. I have also shown how to connect Google Home with Arduino Cloud to control the relays with voice commands. If the ESP8266 connected with Wi-Fi, then you can control the relays from anywhere in the world with the Arduino IoT Cloud mobile app and Google Home. And if there is no internet, still you can control the relays manually with buttons. 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 say "Hey Google, turn on Switch" to control the home appliances.

hi but is it possible to control everything remotely? that is, away from home? thanks

[AsadAli-mzou]

Nice, please make video of 8 channel home automation using KME Smart ....Thanks

[deepbasak]

I uploaded the code into the esp 8266, but it has push button code can you make it for switch. And also make that it can remember it's last stage after power cut. 🙏Please 🙏❤❤.

How to check if node mcu is connected with wifi

[DivitSeenivasan]

Bro i am a diplamo electronics student and doing a project which is a solar ups system with multi sourse power with relay and controller(Arduino uno and gsm module for sms commands). Can u teach me of doing the relay support and interfacing the controller to power and load. Please bro

Congratulations on your contribution, so that we can have more knowledge. I tried to see the code, but there is nothing, it is empty.
