 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.

-# Odroid PowerMate Logger and Plotter
+# Power Consumption Logger Example
 
-This directory contains two Python scripts to log power data from an Odroid PowerMate device and visualize it.
+Based on this script, you can monitor power consumption and implement graph plotting.
 
-1.  `logger.py`: Connects to the device's web server, authenticates, and logs real-time power data from its WebSocket to a CSV file.
+## How to Run the Script
-2.  `csv_2_plot.py`: Reads the generated CSV file and creates a plot image of the power, voltage, and current data over time.
 
-## Prerequisites
+### Install Python Virtual Environment
 
-### 1. Clone this example
+```shell
-```bash
+sudo apt install virtualenv
-git clone https://github.com/hardkernel/odroid-powermate.git
+virtualenv venv
-cd odroid-powermate/example/logger
+. venv/bin/activate
 ```
 
-### 2. Python and Virtual Environment
+### Install require package
 
-It is highly recommended to use a Python virtual environment to manage project dependencies and avoid conflicts with other projects.
+```shell
-
+pip install grpcio-tools requests websockets protobuf
-Ensure you have Python 3 installed.
-
-1.  **Create a virtual environment:**
-    Open your terminal in this directory and run:
-    ```bash
-    python3 -m venv venv
-    ```
-    This will create a `venv` directory containing the Python interpreter and libraries.
-
-2.  **Activate the virtual environment:**
-    *   **On Windows:**
-        ```powershell
-        .\venv\Scripts\activate
-        ```
-    *   **On macOS and Linux:**
-        ```bash
-        source venv/bin/activate
-        ```
-    Your terminal prompt should now show `(venv)` at the beginning, indicating that the virtual environment is active.
-
-### 3. Install Required Libraries
-
-With the virtual environment activated, install the necessary Python packages:
-
-```bash
-pip3 install requests websockets protobuf pandas matplotlib python-dateutil scipy
 ```
 
-### 4. Protobuf Generated File
+### Build `status_pb2.py`
 
-The `logger.py` script uses Google Protocol Buffers (Protobuf) to decode real-time data from the WebSocket. This requires a Python file, `status_pb2.py`, which is generated from a Protobuf definition file (`status.proto`).
+```shell
-
+python -m grpc_tools.protoc -I ../../proto --python_out=. status.proto
-**How to Generate `status_pb2.py`:**
-
-1.  **Install Protobuf Compiler Tools:**
-    You need the `grpcio-tools` package, which includes the `protoc` compiler and Python plugins. You can install it via pip:
-    ```bash
-    pip3 install grpcio-tools
 ```
 
-2.  **Locate the `.proto` file:**
+### Execute script
-    Ensure you have the `status.proto` file in the current directory. This file defines the structure of the data messages.
 
-3.  **Run the Compiler:**
+```shell
-    Execute the following command in your terminal. This command tells `protoc` to look for `status.proto` in the directory (`-I../../proto`) and generate the Python output file (`--python_out=.`) in the same place.
+# python3 logger.py -u <username> -p <password> <address>
-    ```bash
+python3 logger.py -u admin -p password 192.168.30.5
-    python3 -m grpc_tools.protoc -I../../proto --python_out=. status.proto
 ```
-After running this command, the `status_pb2.py` file will be created, and `logger.py` will be able to use it.
-
-## Usage
-
-The process is a two-step workflow: first log the data, then plot it.
-
-### Step 1: Log Power Data with `logger.py`
-
-Run `logger.py` to connect to your Odroid Smart Power device and save the data to a CSV file.
-
-**Syntax:**
-```bash
-python3 logger.py <host> -u <username> -p <password> -o <output_file.csv>
-```
-
-**Arguments:**
-*   `host`: The IP address or hostname of the Odroid Smart Power device (e.g., `192.168.1.50`).
-*   `-u`, `--username`: The username for logging in.
-*   `-p`, `--password`: The password for logging in.
-*   `-o`, `--output`: The path to save the output CSV file. This is required if you want to generate a plot.
-
-**Example:**
-
-This command will log in and save the power data to `power_log.csv`.
-
-```bash
-python3 logger.py 192.168.1.50 -u admin -p mypassword -o power_log.csv
-```
-
-The script will continue to log data until you stop it with `Ctrl+C`.
-
-### Step 2: Generate a Plot with `csv_2_plot.py`
-
-Once you have a CSV log file, you can use `csv_2_plot.py` to create a visual graph.
-You can also use the csv file recorded from PowerMate Web.
-
-**Syntax:**
-```bash
-python3 csv_2_plot.py <input.csv> <output.png> [options]
-```
-
-**Arguments:**
-*   `input_csv`: The path to the CSV file generated by `logger.py`.
-*   `output_image`: The path to save the output plot image (e.g., `plot.png`).
-
-**Optional Arguments:**
-*   `-t`, `--type`: Specify which plots to generate. Choices are `power`, `voltage`, `current`. Default is all three.
-*   `-s`, `--source`: Specify which power sources to include. Choices are `vin`, `main`, `usb`. Default is all three.
-
-**Example 1: Default Plot**
-
-This command reads `power_log.csv` and generates a plot containing power, voltage, and current for all sources, saving it as `power_graph.png`.
-
-```bash
-python3 csv_2_plot.py power_log.csv power_graph.png
-```
-
-**Example 2: Custom Plot**
-
-This command generates a plot showing only the **power** and **current** for the **MAIN** and **USB** sources.
-
-```bash
-# main, usb power consumption
-python csv_2_plot.py power_log.csv custom_plot.png --type power --source main usb
-```
-
-## Example Output
-
-Running the plot script will generate an image file similar to this:
-
-![plot.png](img/plot.png)
-
-The 5-unit scale is highlighted with a blue dotted line, and the 10-unit scale is highlighted with a red dotted line.
