✨ Features

• Real-time Monitoring: Live sensor data visualization with configurable refresh rates
• gping-inspired UI: Clean interface with statistics table and interactive chart
• Unit-based Filtering: Automatically groups sensors by units, supports up to 2 units simultaneously
• Dual Y-axes: Charts can display different units on left and right axes
• Clean Interface: Focused visualization without unnecessary interactive distractions
• Responsive Design: Automatically adapts to terminal size with compact mode
• Fuzzy Sensor Matching: Partial sensor name matching with suggestions
• Rich Statistics: Min, max, average, and 95th percentile calculations

📦 Installation

Windows (Recommended)

winget install hwinfo-tui

Or download the portable executable - no installation required.

Cross-Platform

pip install hwinfo-tui

From Source

git clone https://github.com/hwinfo-tui/hwinfo-tui.git
cd hwinfo-tui

# Quick setup (recommended)
./setup.sh  # or setup.bat/setup.ps1 on Windows

# Manual setup
python -m venv venv
source venv/bin/activate  # or venv\Scripts\activate on Windows
pip install -e .

🚀 Quick Start

1. Configure HWInfo64 logging (Windows): Open HWiNFO → Sensors → Start Logging → Choose CSV format and location

2. Monitor sensors:

   # Basic usage
   hwinfo-tui monitor sensors.csv "CPU Package"
   
   # Multiple sensors
   hwinfo-tui monitor sensors.csv "Core Temperatures" "GPU Temperature" "CPU Package"
   
   # Mixed units with custom settings
   hwinfo-tui monitor sensors.csv "Total CPU Usage" "Core Temperatures" --refresh-rate 0.5 --time-window 600

💡 Usage Examples

# Single unit (temperature)
hwinfo-tui monitor sensors.csv "Core Temperatures" "GPU Temperature" "CPU Package"

# Single unit (percentage)
hwinfo-tui monitor sensors.csv "Total CPU Usage" "GPU Core Load" "GPU Memory Usage"

# Dual units (temperature + percentage)
hwinfo-tui monitor sensors.csv "Core Temperatures" "Total CPU Usage" "GPU Temperature"

# Dual units (power + temperature)
hwinfo-tui monitor sensors.csv "CPU Package Power" "CPU Package" "GPU Power"

# List available sensors
hwinfo-tui list-sensors sensors.csv
hwinfo-tui list-sensors sensors.csv --unit "°C" --limit 20

📋 Command Line Reference

Main Command

Usage: hwinfo-tui [OPTIONS] COMMAND [ARGS]...

A gping-inspired terminal visualization tool for monitoring real-time hardware sensor data from HWInfo.

Options:

• --version - Show version information and exit
• --install-completion - Install completion for the current shell
• --show-completion - Show completion for the current shell
• --help - Show this message and exit

Commands:

• monitor - Monitor hardware sensors in real-time
• list-sensors - List all available sensors in the CSV file

---

monitor

Usage: hwinfo-tui monitor [OPTIONS] CSV_FILE SENSOR_NAMES...

Monitor hardware sensors in real-time.

Arguments:

• CSV_FILE (required) - Path to HWInfo sensors.csv file
• SENSOR_NAMES... (required) - One or more sensor names to monitor (supports partial matching)

Options:

• -r, --refresh-rate FLOAT - Update frequency in seconds (0.1-60.0) [default: 1.0]
• -w, --time-window INTEGER - History window in seconds (10-7200) [default: 300]
• --help - Show this message and exit

---

list-sensors

Usage: hwinfo-tui list-sensors [OPTIONS] CSV_FILE

List all available sensors in the CSV file.

This command helps you discover sensor names for monitoring.

Arguments:

• CSV_FILE (required) - Path to HWInfo sensors.csv file

Options:

• -u, --unit TEXT - Filter sensors by unit (e.g., '°C', '%', 'W')
• -l, --limit INTEGER - Maximum number of sensors to display (1-1000) [default: 50]
• --help - Show this message and exit

⚙️ HWInfo64 Setup (Windows)

1. Download and install HWInfo64 (Windows only)
2. Open Sensors window → File → Start Logging
3. Choose CSV format and location
4. Set logging interval (1-2 seconds recommended)
5. Use the generated CSV file with HWInfo TUI

🔧 Unit Filtering

HWInfo TUI automatically filters sensors based on their units:

• Single Unit: All sensors with the same unit (e.g., °C)
• Dual Units: Up to 2 different units on separate Y-axes
• Auto-exclusion: Incompatible sensors excluded with warnings

# Third unit [W] would be excluded and show a warning
hwinfo-tui monitor sensors.csv "Core Temperatures" "Total CPU Usage" "CPU Power"

💻 System Requirements

• Python: 3.8 or higher
• Terminal: Any modern terminal with color support
• Platform: Windows (HWInfo64 is Windows-only)
• Dependencies: typer, rich, plotext, pandas, watchdog

Note: While HWInfo TUI can run on any platform with Python, HWInfo64 is only available for Windows. On other platforms, you can use HWInfo TUI with CSV files generated on Windows.

🚀 Performance

• Memory Usage: < 50MB baseline, < 100MB with full data retention
• CPU Overhead: < 2% of single core during normal operation
• Startup Time: < 2 seconds from launch to first display
• Update Frequency: Configurable from 0.1 to 60 seconds

🛠️ Troubleshooting

No matching sensors found

hwinfo-tui list-sensors sensors.csv  # Check available sensors
hwinfo-tui monitor sensors.csv "CPU" "GPU"  # Use partial names

Too many units excluded

• Maximum 2 units supported - group sensors by similar units

File not found

• Ensure HWInfo is actively logging to the CSV file
• Verify file path and permissions

Poor performance

hwinfo-tui monitor sensors.csv "CPU" --refresh-rate 2.0 --time-window 120

Debug mode

HWINFO_TUI_LOG_LEVEL=DEBUG hwinfo-tui monitor sensors.csv "CPU"
