System Performance Notifier Service

A lightweight Windows service that monitors system performance (CPU, GPU, RAM, Temperatures) and transmits real-time data to an ESP32 display via USB/Serial.

🚀 Features

• Real-time Monitoring: CPU/GPU usage & temps, RAM utilization.
• Hardware Support: Supports modern hardware (Intel Core Ultra, RTX 40/50 series) via AIDA64.
• Plug & Play: Auto-detects ESP32 devices and handles reconnections.
• Background Service: Runs silently as a Windows Service.

📋 Requirements

• OS: Windows 10 / 11 (64-bit)
• Software:
  • .NET 9.0 Runtime
  • AIDA64 Extreme/Engineer (Recommended for sensor data)
• Hardware: ESP32-S3 Development Board with Display (e.g., ESP32-8048S050)

🛠️ Installation & Setup

1. Configure Sensors (AIDA64)

For the most reliable temperature readings (especially on newer motherboards like ASUS Z890), we use AIDA64's Shared Memory feature.

1. Open AIDA64.
2. Go to File > Preferences > Hardware Monitoring > External Applications.
3. ✅ Check "Enable Shared Memory".
4. Click OK.

2. Install the Service

The included PowerShell script handles building, installing, and starting the service.

1. Open PowerShell as Administrator.
2. Navigate to the Scripts folder.
3. Run the installer:

   cd Scripts
   .\service-manager.ps1 install

3. ESP32 Setup

1. Flash your ESP32 with the compatible firmware (Arduino/PlatformIO project).
2. Connect the ESP32 to your PC via USB.
3. The service will automatically detect the device (looking for USB Vendor ID 1A86 by default).

🎮 Management

You can manage the service using the interactive menu:

.\Scripts\service-manager.ps1

Or use simple commands:

• Check Status: .\Scripts\service-manager.ps1 status
• View Logs: .\Scripts\service-manager.ps1 logs -Live
• Restart: .\Scripts\service-manager.ps1 restart
• Uninstall: .\Scripts\service-manager.ps1 uninstall

⚙️ Configuration (appsettings.json)

Located in the installation directory (usually bin\Release\net9.0-windows\win-x64).

{
  "SystemMonitor": {
    "SerialPort": "AUTO",          // "AUTO" or specific port like "COM3"
    "BaudRate": 115200,
    "TransmissionInterval": 1000,  // Update every 1 second
    "ESP32VendorId": "1A86",       // Change if using a different ESP32 board
    "ESP32ProductId": "7523"
  }
}

Loading

1. Data Collection: The service reads data from AIDA64 Shared Memory (or WMI/Performance Counters as fallback).
2. Processing: Data is formatted into a compact JSON object.
3. Transmission: JSON is sent over USB Serial to the ESP32.
4. Display: ESP32 parses JSON and updates the UI.

❓ Troubleshooting

"CPU Temp is 0°C"

• Ensure AIDA64 is running.
• Ensure "Enable Shared Memory" is checked in AIDA64 preferences.
• Check logs: .\Scripts\service-manager.ps1 logs

"ESP32 Not Detected"

• Check USB cable connection.
• Verify the Vendor ID in appsettings.json matches your device (Check Device Manager > Ports > Details > Hardware Ids).
