- In this IoT project, I have shown you how to make the Arduino IoT Cloud with Alexa home automation system using NodeMCU ESP8266, and Arduino UNO to control relays with voice commands, IR remote, and manual switches. You also monitor the room temperature and real-time feedback in the Amazon Alexa app. I have used all the FREE tools for this IoT-based smart home system.

Important points:
1. You can also use Arduino Nano instead of Arduino UNO.
2. Use the IR receiver with a metal case.
4. You can use any IR remote, just get the HEX code as shown and update it in the main Arduino sketch.
5. Install the proper version of the Arduino libraries (as mentioned in the code).
6. Arduino EEPROM will store the previous states after the power cuts.
7. Please watch the complete video, otherwise you may face some issues.
8. You don't need any Alexa devices like Echo Dot. You can just use Alexa App for this IoT project.
**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 Arduino NodeMCU smart home system with Arduino Cloud to control the home appliances with and without internet. If NodeMCU is connected with WiFi then you can control the relays from anywhere in the world with Alexa. And you can also monitor the real-time feedback in the Amazon Alexa IoT applications. So with this smart home project, you can convert any appliance to IoT devices and control them through the internet.
So, now you can just say "Alexa, turn on light". that's it.

Very Informative Dada
Excelente proyecto 👌
great project friend , however I wanna ask what type of data warehouse manages the data in this project ? is it simple log files or is it within the cloud servers of amazon through the alexa app ?
You are legend
Good morning buddy, I would like to learn about Arduino, can I just get one from Ebay and go from there?
Sir, Can do ? Ethernet shield +Arduino Mega control 16chanel realy + 16 Maual switches.
Temparature is showing as 0.3 or smtime 0.33 degree in arduino cloud platofrm and even in alexa app also whats the reason
how did you download the esp8266 board and the library cause you just linked the github links?
Can i connect Arduino mega with NodeMCU esp8266 and then connect to thingspeak to visualize sensor data?
Podrías usar acces point para hacer prácticas
Make a project with blynk 2.0 and also add a fan speed controller
What is the power the bulb you are using?
Will 8266 work on 5v power supply? It needs 3.3 v
Saludos amigo tienes algún vídeo con eso 32 dónde pueda controlar la intencidad de LED ?
👍👍👍👍👍
bro code and files are not available on which link you shared shared .
Can i use esp32 cam model instead of esp32 dev kit ?
Can we make this project using node mcu?
hello can someone help me how to change the code to esp 32 im doing this for my project but im not good in coding
