Modern hardware information and monitoring tool for Linux — built with Python 3 + PyQt6.
Fast, beautiful, and accurate. Think HWiNFO meets Neofetch, with a clean dark UI.
| Category | Details |
|---|---|
| CPU | Name, cores/threads, frequency (live), temperature, cache, per-core usage bars |
| GPU | NVIDIA / AMD / Intel, VRAM, utilization, temperature, driver, clocks |
| RAM | Total/used/available, swap, type, speed, slots |
| Storage | SSD/HDD/NVMe detection, SMART status, read/write speed, partitions |
| Network | All interfaces, IPv4/IPv6, WiFi SSID/signal, live bandwidth charts |
| Sensors | Temperatures, fan RPM, battery (via lm_sensors / hwmon) |
| System | OS, kernel, DE, shell, uptime, mainboard, BIOS, package count |
| Export | JSON, TXT, PDF |
| Live charts | Smooth rolling charts, no external chart library needed |
sudo pacman -S python python-pyqt6 python-psutil lm_sensors smartmontools \
mesa-utils vulkan-tools pciutils usbutils dmidecodepip install -r requirements.txtgit clone https://github.com/yourname/hwsonnet
cd hwsonnet
./install.shThe installer:
- Checks for missing pacman packages
- Installs Python dependencies via pip
- Creates a
.desktopfile for your app launcher - Creates a
hwsonnetcommand in~/.local/bin
python main.py
# or after install:
hwsonnetFor accurate temperature and fan data:
sudo sensors-detect # follow prompts, then reboot or modprobe the suggested modules
sensors # verify outputRequires the proprietary NVIDIA driver (not nouveau):
sudo pacman -S nvidia nvidia-utils
# nvidia-smi should be available after driver installationWorks out of the box via /sys/class/drm — no extra packages needed.
sudo pacman -S smartmontools
# Run HWSonnet as root, or add yourself to the 'disk' group:
sudo usermod -aG disk $USERhwsonnet/

- MVVM-inspired: collectors = Model, pages = View+ViewModel, workers = async binding
- No blocking UI: all I/O and subprocess calls run in
QThreadworkers - No external chart library: live charts drawn entirely with
QPainter - Graceful degradation: missing tools (nvidia-smi, dmidecode, smartctl) → "N/A"
