IoT Home Automation

A 🌐 Flask-based IoT home automation dashboard that allows users to control and monitor various smart home devices like lights, thermostats, and door locks through a user-friendly web interface.

---

⚙️ Features

• 🏡 Thermostat Control: Set and view target temperature.
• 💡 Light Control: Toggle lights on and off.
• 🔒 Door Lock Control: Lock and unlock doors remotely.
• 📊 Real-Time Status Updates: View the current status of all devices on the dashboard.

🛠️ Technologies Used

•    The programming language used to build the backend of the application, allowing communication between the web server and smart devices.

•    A simple web framework that helps create the web server and manage user requests from the interface.

•    A database system used to store logs of device actions and track history. It keeps records of what devices do over time.

• Frontend Technologies: HTML, CSS, JavaScript (with AJAX for smooth updates) These are used to create the user interface of the application, making it easy for users to interact with their smart devices.

• Device Control Architecture: Uses a Model-View-Controller (MVC) design to manage how devices are controlled and how information is displayed, keeping things organized and efficient.

🚀 Getting Started

Prerequisites

• Python 3.7 or later
• MySQL server for logging device interactions
• Required Python packages listed in requirements.txt

Installation

1. Clone the repository:

   git clone https://github.com/AlexLeetDev/IoT_Home_Automation.git
   cd IoT_Home_Automation

2. Set up a virtual environment:

   python -m venv venv

3. Activate the virtual environment:

   • On Windows:

     .\venv\Scripts\activate

   • On macOS/Linux:

     source venv/bin/activate

4. Install the required packages:

   pip install -r requirements.txt

Database Configuration

1. Start your MySQL server.

2. Create the necessary database and tables:

   CREATE DATABASE iot_home_automation;
   USE iot_home_automation;
   
   CREATE TABLE Devices (  
       device_id INT AUTO_INCREMENT PRIMARY KEY,  
       device_name VARCHAR(255),  
       device_type VARCHAR(255),  
       location VARCHAR(255),  
       created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP  
   );
   
   CREATE TABLE EventLogs (  
       log_id INT AUTO_INCREMENT PRIMARY KEY,  
       device_id INT,  
       event_type VARCHAR(255),  
       event_value VARCHAR(255),  
       event_timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP,  
       FOREIGN KEY (device_id) REFERENCES Devices(device_id)  
   );

3. Configure MySQL connection in your project files.

   Update the connection settings directly within each device file:

   db = mysql.connector.connect(
    host="localhost",
    user="your_username",
    password="your_password",
    database="iot_home_automation"
   )

🖥️ Usage

Once the application is running, you can use the IoT Home Automation dashboard to interact with connected devices. Here’s how each feature works:

• Adjust Thermostat:

  • Set a desired target temperature for your thermostat by entering a value and clicking the "Adjust" button.
  • The dashboard will display both the current temperature and your target setting.

• Toggle Light:

  • Click the "Toggle Light" button to switch the light on or off.
  • The current status of the light (On/Off) is displayed on the dashboard.

• Toggle Door Lock:

  • Click the "Toggle Door Lock" button to lock or unlock the door.
  • The dashboard will show the door’s current state (Locked/Unlocked).

Each control action sends a request to the backend, which updates the device status in real-time. This enables easy and convenient management of your smart home devices from a single interface.
