Introduction
Have you ever wanted to control your home appliances with a simple tap on your smartphone? With the ESP32 WiFi Bluetooth Smart Home Automation project, you can do just that. This project allows you to control eight lamps using a manual switch and the Blynk app, giving you complete control over your home appliances from anywhere.
Getting Started
To create this smart home automation system, you will need the following components:
- ESP32
- 8-channel relay module
- Existing switchboard
Once you have these components ready, follow the circuit diagram provided to connect them accordingly. To make the circuit more compact, we recommend designing a custom PCB using JLCPCB. Their affordable price and premium quality make them a reliable choice for custom design PCB projects.
Configuring the Blynk App
To control the eight relays from the Blynk app, you need to configure it accordingly. Download the Blynk app from the Google Play Store or App Store, and create a new project named “ESP32 Automation”. Select the “ESP32 Dev board” as the connection type, and choose “Wi-Fi” as the connection method. Blynk will send an authentication token to your email, which you need to copy and paste into the code.
Add eight virtual buttons to the Blynk app to control the relays. Configure each button with the appropriate virtual pin and set the mode to “switch”. This will allow you to turn the relays on and off with a simple tap on the app.
Uploading the Code
Download the code for this project from our website iotcircuithub.com and install the ESP32 board and required libraries. In the code, enter your Wi-Fi credentials and the authentication token provided by Blynk. Once you have made these changes, upload the code to the ESP32 board.
Controlling Your Home Appliances
After successfully uploading the code, connect the lamps to the relay module as per the circuit diagram. Supply 5 volts to the ESP32 using a mobile charger, and turn on the power supply. Install the “Bluetooth Switch” app on your smartphone and pair it with the ESP32. Now, you can control your home appliances using the Blynk app and the manual switch.
FAQs
Q: Can I control my home appliances without an internet connection?
A: Yes, you can control your appliances using the manual switch and the Bluetooth app even without an internet connection.
Q: How many appliances can I control with this project?
A: This project allows you to control up to eight appliances using the Blynk app and the manual switch.
Q: Can I customize the app interface?
A: Yes, you can customize the Blynk app interface by adding additional buttons and modifying the existing ones.
Conclusion
Creating your own smart home automation system is now within reach. With the ESP32 WiFi Bluetooth Smart Home Automation project, you can control your home appliances with ease using the Blynk app and a manual switch. By following the provided circuit diagram, configuring the Blynk app, and uploading the code, you will have a fully functional smart home automation system at your fingertips.
