Web-Based Remote Garage Door Controller

The DoorController project enables the creation of a remote garage door controller that functions without requiring modifications to an existing garage door unit. This innovative design leverages a spare remote garage door controller powered by the ESP32's 3.3V output, combined with an economical magnetic (reed) switch to monitor the door's open and closed status. The magnetic switch is easily mounted on the garage door, while the reed sensor is positioned on the adjacent wall, facilitating a simple installation process.

Key Features

• Minimal Installation Effort: The design allows for easy setup without altering the garage door hardware. The electronics are housed in a compact box mounted above the magnetic switch, keeping the assembly neat and organized.

Functional Overview

The garage door controller draws power directly from the ESP32's 3.3V output, and it employs an NPN transistor to simulate a button press, effectively mimicking the action of a garage door's physical button click. The transistor's configuration provides a streamlined setup while ensuring reliable operation.

Components Used

The project can be built using the following key components, although compatible alternatives may be suitable:

• XIAO ESP32S3
• Garage Stop (Generic garage door controller)
• NC Magnetic Switch (Reed Switch)
• ElectroCookie Mini PCB Solderable Prototype Board
• Basic Starter Kit for Arduino (Includes components like a breadboard, NPN transistor, and cables)

Software Configuration

The accompanying software is provided as ready-to-use source code, implemented in the Lua scripting language. Users can easily adapt the code if desired, but it is functional as-is with the specified GPIO pin configurations.

Steps to Set Up the Project:

1. Development Environment: Install the Xedge32 development environment.
2. Clone Repository: Obtain the project files from GitHub:

   git clone https://github.com/jjsch-dev/DoorController
   cd DoorController/app
   zip -D -q -u -r -9 ../DoorController.zip .
   

3. Upload to ESP32: Use the Xedge32 IDE to upload the application to the ESP32.
4. Testing: Verify the app is functioning correctly and test its features, including accessing the garage door interface through your web browser.

Mobile Access

Users can conveniently control their garage doors from mobile devices. By adding the controller's web interface to their mobile home screen, they can seamlessly access the system from anywhere within the WiFi range.

Email Notifications

The project also includes the capability to send email notifications regarding the garage door's open or closed status. This feature can be configured via the SMTP settings in the Xedge32 IDE, allowing users to receive updates automatically.

Source Code Insight

This smart application is built with a global reactive state for real-time synchronization across multiple clients. Key pieces of code include logic for user management, sensor handling, and integration with the web interface, ensuring a responsive and intuitive user experience.

This web-based remote garage door controller serves as an effective solution for modernizing home automation systems. Its installation is straightforward, and the configuration is flexible, making it suitable for various setups.
