+# Deye Charge Speed Monitor
 
-https://github.com/jmccrohan/pysolarmanv5
+A Flask-based application for monitoring Deye Inverters (and compatible models) using the Solarman V5 protocol. This tool connects directly to the inverter via Modbus over TCP to read real-time data including voltages, currents, battery status, and BMS information.
 
-https://pysolarmanv5.readthedocs.io/en/stable/
+## Features
 
-https://pysolarmanv5.readthedocs.io/en/stable/examples.html
+- **Real-time Monitoring**: Reads critical data such as Input/Output Voltage, Grid/Load Currents, Battery SOC, Temperature, and Power.
+- **BMS Integration**: Retrieves detailed Battery Management System (BMS) data for up to two battery packs.
+- **Web Interface**: Provides a user-friendly dashboard to view inverter status (served at `/`).
+- **JSON API**: Exposes raw data via a RESTful endpoint (`/api/data`) for integration with other systems.
+- **PDF Utility**: Includes a tool to extract register information from Deye Modbus PDF manuals.
+
+## Prerequisites
+
+- Python 3.x
+- A Deye Inverter (or compatible) connected to the network.
+- Inverter IP address, Serial Number, and Modbus Slave ID.
+
+## Installation
+
+1.  **Clone the repository:**
+
+    ```bash
+    git clone <repository-url>
+    cd deyeChargeSpeed
+    ```
+
+2.  **Create and activate a virtual environment:**
+
+    ```bash
+    python -m venv venv
+    # Windows
+    .\venv\Scripts\activate
+    # Linux/Mac
+    source venv/bin/activate
+    ```
+
+3.  **Install dependencies:**
+
+    ```bash
+    pip install -r requirements.txt
+    ```
+
+4.  **Configuration:**
+
+    Copy the example configuration file and update it with your inverter details:
+
+    ```bash
+    cp config.py.example config.py
+    ```
+
+    Edit `config.py`:
+    ```python
+    INVERTER_IP = "192.168.x.x"
+    INVERTER_SERIAL = 1234567890
+    INVERTER_PORT = 8899
+    INVERTER_SLAVE_ID = 1
+    ```
+
+## Usage
+
+1.  **Start the application:**
+
+    ```bash
+    python app.py
+    ```
+
+2.  **Access the dashboard:**
+
+    Open your web browser and navigate to `http://localhost:5000`.
+
+## Utilities
+
+### PDF Register Extractor
+
+Located in `docs/extract_pdf.py`, this script helps identify Modbus registers from Deye PDF manuals.
+
+**Usage:**
+1.  Place your PDF manual in the `docs/` folder.
+2.  Update the filename in `docs/extract_pdf.py` if necessary (defaults to `Modbus储能-组串-微逆宁波德业V118-1.pdf`).
+3.  Run the script:
+    ```bash
+    python docs/extract_pdf.py
+    ```
+4.  Check `pdf_output.txt` for the extracted register locations and context.
