• 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

winget install hwinfo-tui

Or download the portable executable - no installation required.

pip install hwinfo-tui

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 .

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

# 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

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

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]
• --stale-after INTEGER - Mark the data stale after this many seconds without a new row (3-3600) [default: 15]
• --help - Show this message and exit

Live logs: monitor follows HWiNFO's log for as long as it runs. You can start it before HWiNFO logs, or point it at a file that doesn't exist or isn't readable yet, and it shows a waiting screen until the file has the sensors and data. When HWiNFO stops and restarts logging (truncating or recreating the file), the monitor reopens it on its own. When rows stop arriving, a yellow "Stale" bar says so, and it clears when they resume.

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

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

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"

• Python: 3.10 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.

• 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

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

Stuck on "Waiting for HWiNFO to log"

• Ensure HWInfo is actively logging to the CSV file (Sensors > Logging start)
• Verify the file path and permissions; the screen names the file and what is missing

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"
