+# ODROID Remote HTTP Power Manager (OWPM)
+
+A web-based remote power and monitoring tool for ODROID Single Board Computers (SBCs), powered by an ESP32. This project provides a comprehensive web interface to control power, monitor real-time metrics, and access the serial console of your ODROID from any web browser on your local network.
+
+## Features
+
+- **Web-Based UI**: Modern, responsive interface built with Bootstrap and vanilla JavaScript.
+- **Power Control**: Independently toggle Main (e.g., 12V) and USB (5V) power supplies.
+- **Power Actions**: Remotely trigger Reset and Power On/Off actions.
+- **Real-time Metrics**: Monitor voltage, current, and power consumption with a live-updating graph.
+- **Interactive Serial Terminal**: Access your ODROID's serial console directly from the web UI via WebSockets.
+- **Wi-Fi Management**:
+    - Scan and connect to Wi-Fi networks (STA mode).
+    - Enable Access Point mode (AP+STA) to connect directly to the device.
+    - Configure static IP settings.
+- **System Info**: View device uptime and connection status.
+- **Customizable Theme**: Switch between light and dark modes, with the preference saved locally.
+
+## Prerequisites
+
+Before you begin, ensure you have the following installed and configured on your system:
+
+- **[ESP-IDF (Espressif IoT Development Framework)](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html)**: This project is developed and tested with ESP-IDF v5.x.
+- **[Node.js and npm](https://nodejs.org/)**: Required to build the web application. Node.js LTS version (e.g., 18.x or later) is recommended.
+
+## How to Build and Flash
+
+1.  **Clone the repository:**
+    ```bash
+    git clone <your-repository-url>
+    cd odroid-remote-http
+    ```
+
+2.  **Build the Web Application:**
+    The web interface needs to be compiled before building the main firmware.
+    ```bash
+    cd page
+    npm install
+    npm run build
+    cd ..
+    ```
+
+3.  **Set up the ESP-IDF environment:**
+    Open a terminal and source the ESP-IDF export script. The path may vary depending on your installation location.
+    ```bash
+    . $HOME/esp/esp-idf/export.sh
+    ```
+
+4.  **Set the target chip:**
+    Specify your ESP32 variant (e.g., `esp32`, `esp32s3`).
+    ```bash
+    idf.py set-target esp32
+    ```
+
+5.  **(Optional) Configure the project:**
+    You can configure project-specific settings, such as default Wi-Fi credentials, by running `menuconfig`.
+    ```bash
+    idf.py menuconfig
+    ```
+
+6.  **Build the project:**
+    This command compiles the application, bootloader, partition table, and embeds the compiled web page data.
+    ```bash
+    idf.py build
+    ```
+
+7.  **Flash the firmware:**
+    Connect your ESP32 board to your computer and replace `/dev/ttyUSB0` with your device's serial port.
+    ```bash
+    idf.py -p /dev/ttyUSB0 flash
+    ```
+
+8.  **Monitor the output:**
+    To view the serial logs from the device, use the `monitor` command. This is useful for finding the device's IP address after it connects to your Wi-Fi.
+    ```bash
+    idf.py -p /dev/ttyUSB0 monitor
+    ```
+    To exit the monitor, press `Ctrl+]`.
+
+## Usage
+
+1.  After flashing, the ESP32 will either connect to the pre-configured Wi-Fi network or start an Access Point (AP).
+2.  Check the serial monitor logs to find the IP address assigned to the device in STA mode, or the default AP address (usually `192.168.4.1`).
+3.  Open a web browser and navigate to the device's IP address.
+4.  You should now see the ODROID Remote control panel.
