In this IoT project, I have shown how to make Alexa home automation project with manual switches using NodeMCU or ESP8266 and relay module. With this internet of things project, you can control 4 home appliances from Alexa and manual switches with and without internet. So this is a very useful homemade IoT based home automation system that you can easily make with NodeMCU, Relay Module, Push Buttons, and Alexa Echo Dot devices.

For this Alexa smart home project, I have not used any custom design PCB or any third-party IoT Apps. I have used Amazon Alexa App to connect NodeMCU with Alexa Echo Dot, so after watching this tutorial video you can make this useful NodeMCU project at home.

Required components for this project from amazon.com (Affiliate link):
1. NodeMCU amzn.to/2WoR2A2
2. 4-channel Relay Module (5V) amzn.to/3r2HuJ4
3. Push Buttons
4. Alexa Echo Dot Smart Speaker amzn.to/37sSd84

Required components for this project from amazon.in (Affiliate link):
1. NodeMCU amzn.to/3fJA4EG
2. 4-channel Relay Module (5V) amzn.to/2BQ5Y3o
3. Push Buttons
4. Alexa Echo Dot Smart Speaker amzn.to/2PkTOTe

During the video, I have shared the circuit and code for this IoT project. So after watching the complete tutorial video you can easily make this ESP8266 Alexa smart home project.

There is a limitation, the NodeMCU, and the echo dot smart speaker should be connected with the same wifi network.

Soon I will publish the complete article on my website and share the link here.

If you face any issue please let me know in the comment section.
