Unofficial Linux port of the Thermal Grizzly WireView Pro II desktop application. Built with .NET 8.0 and Avalonia UI.
A Windows build (WireView Plus) is also available on the Releases page - see Windows under Installation.
- Real-time monitoring - Voltage, current, and power readings across all 6 pins with live charts, plus custom charts: pick any telemetry series, per-series colors, manual or auto Y scaling
- Device configuration - Fan speed, display settings, fault alarms, thresholds
- Configuration profiles - Save, load, and manage named device configurations
- Data logging - On-device log readback and CSV export, browsable per power cycle
- Desktop notifications - Via
notify-send - Software shutdown on fault - Optional system shutdown when a fault alarm triggers, for eGPU or setups where the hardware shutdown header cannot be connected
- LAN monitoring - Read WireViews on other machines over the network, optionally publish this host's device, and remotely view/edit a remote device's configuration (HMAC-authenticated). See LAN monitoring below
- Theme editor - Customize the device display: background images, text and highlight colors, display inversion, with a live preview. Theme files (.wv2t) are compatible with the official Windows app
- Firmware updates - Flash the bundled firmware (v05, build 20260902_0741) from the Device page over USB DFU. Requires the
dfu-utilpackage; compares the bundled and device firmware by version and build date, refuses an image made for another product, and warns before downgrades
Warning: firmware flashing restarts the device into its STM32 bootloader and rewrites its flash. It follows the same DFU procedure as the official Windows client (and refuses to start if
dfu-utilor the firmware image is missing), but a power loss or unplug mid-flash can leave the device unbootable until reflashed manually. This is unofficial software, not affiliated with or endorsed by Thermal Grizzly: flash at your own risk. The previous experimentaldfu-enabledbranch has been removed in favor of this built-in implementation.
hwmon integration: If you want sensor data exposed to
sensors, Grafana, conky, btop, and other monitoring tools via/sys/class/hwmon/, see wireview-hwmon. The kernel module and daemon work standalone without this app, and this app can also use them as an alternative to direct serial communication (see below). That project also includeswireviewctl, a CLI tool for monitoring and scripting device commands from the terminal.
The app supports two ways of communicating with the device:
| Mode | How it works | Features |
|---|---|---|
| Direct serial | App talks to the device over /dev/ttyACM* |
Full control (default) |
| hwmon + daemon | App reads sensors from /sys/class/hwmon/, sends commands via the wireviewd daemon socket |
Full control, plus sensor data available to system monitoring tools |
The app auto-detects the connection mode at startup. If the wireview-hwmon kernel module is loaded, the app uses hwmon for sensor data and connects to the daemon's Unix socket (/run/wireviewd.sock) for commands - configuration read/write, fault clearing, screen control, and device info all work through the daemon. If the daemon is not running, the app still displays sensor data in read-only mode.
Commands that change the device through the daemon (configuration writes, NVM store/reset, firmware flashing, and the serial handover used by log reads and the theme editor) need root or membership of the wireview group, which the wireview-hwmon packages create: sudo usermod -aG wireview $USER. Reading sensors needs no group. Without it the app reports the refused action with that hint, and the automatic theme preview is skipped. Use wireview-hwmon 1.7.0 or later: 1.6.0 refused wireview group members when wireviewd ran under systemd, and only 1.7.0 reports the product, so with an older daemon a Noctua Edition is shown as a WireView Pro II.
If the kernel module is not loaded, the app falls back to direct serial communication automatically.
Beyond the single local device, the app can monitor and control WireViews on other machines over the LAN - one desktop reading several servers, or two PCs watching each other.
In Settings → Remote hosts, add a comma-separated list of hosts
(192.168.1.50, or host:port for a custom port - default 9876). Each remote
device appears in the device picker as lan @ host alongside local ones, with
full live monitoring. A remote host is typically the
wireviewd daemon (Linux/Unraid) or
another copy of this app with publishing enabled (Windows).
Settings → Publish this host on the LAN opens a listener (default port
9876, configurable) so other instances can read this machine's device. Off
by default. On Linux the wireviewd daemon owns publishing, so the toggle is
hidden there.
Set the same Network secret on the publisher and the reader to allow writing to a remote device - screen changes, NVM store/reset, clear-faults, and the full configuration editor all work against a remote device. Requests are signed with HMAC-SHA256 (the secret never crosses the wire; replays rejected). Reading a remote needs no secret; only writes do, and failures are surfaced precisely (e.g. "set the network secret", "rejected by the remote host", "the remote host is unreachable").
Publishing is independent of reading - you can read remote hosts without exposing your own. There is no TLS; this targets a trusted LAN.
- Linux with USB support (tested on Ubuntu 24.04 / 26.04 LTS, Fedora 43-44, and Arch Linux; also packaged for Arch-based distros via the AUR and immutable distros like Bazzite / Silverblue via Flatpak)
- A Thermal Grizzly WireView Pro II or WireView Pro II Noctua Edition connected via USB (Noctua Edition support is tested against simulated devices only; the WireView II and its Phanteks Edition are not supported yet)
- For the hwmon + daemon mode: wireview-hwmon 1.7.0 or later
- Optional:
dfu-utilfor in-app firmware flashing (the Flatpak bundles it; deb/rpm/AUR packages list it as a recommended/optional dependency)
A self-contained Windows build, WireView Plus, is published on the Releases page (wireview-plus-<version>-windows-x64.zip). Extract it and run the executable - no installation or .NET runtime required.
sudo add-apt-repository ppa:sparvoli/wireview-hwmon
sudo apt update
sudo apt install wireview-linuxTo also install the hwmon kernel module and daemon for system-wide sensor integration:
sudo apt install wireview-hwmon wireview-hwmon-dkmsA pre-built .deb package is available on the Releases page. Download it and install:
sudo apt install ./wireview-linux_*_amd64.debsudo dnf copr enable emaspa/wireview-linux
sudo dnf install wireview-linuxOr grab the standalone .rpm from the Releases page - a single RPM works on all current Fedora releases (tested on 42, 43, and 44):
sudo dnf install ./wireview-linux-*.x86_64.rpmTo also install the hwmon kernel module and daemon for system-wide sensor integration (same COPR repo):
sudo dnf install wireview-hwmon wireview-hwmon-dkmsThe package is a self-contained binary - no .NET runtime is required. For immutable, atomic distros (Bazzite, Silverblue, Kinoite), use the Flatpak below instead.
A .flatpak bundle is available on the Releases page:
flatpak install ./wireview-linux-*.flatpak
flatpak run io.github.emaspa.WireViewLinuxThe Flatpak supports direct USB serial mode. A sandbox cannot install udev rules, so install the rule on the host once:
sudo curl -fsSL https://raw.githubusercontent.com/emaspa/wireview-linux/main/udev/99-wireview.rules \
-o /etc/udev/rules.d/99-wireview.rules
sudo udevadm control --reload-rules && sudo udevadm triggerwireview-linux-bin installs the pre-built release binary (no .NET SDK, no compile) and tracks the latest release:
paru -S wireview-linux-bin # or: yay -S wireview-linux-binA community source package, wireview-linux (maintained by arakmar), builds from source instead - note it may lag behind the latest release:
paru -S wireview-linuxTo also install the hwmon kernel module and daemon for system-wide sensor integration, load the module and enable the daemon after installing:
paru -S wireview-hwmon wireview-hwmon-dkms
sudo modprobe wireview_hwmon
sudo systemctl enable --now wireviewdFrom the next boot onward both come up automatically (the dkms package registers the module in modules-load.d and the service modprobes it on start).
The package installs above (PPA, .deb, .rpm, AUR) install the udev rule and
the system reloads it automatically, so serial access works out of the box
for the user logged in at the local seat - the rule makes the serial port and
the DFU bootloader 0660 root:dialout and gives the active session a logind
uaccess ACL, so no group membership or logout is needed there. The rule
matches the one shipped by wireview-hwmon.
If access still fails in an unusual setup (for example over SSH, where the
uaccess ACL doesn't apply), add yourself to the dialout group and log back
in:
sudo usermod -aG dialout "$USER"The tarball is self-contained: the app binary, the udev rule, and a one-time
install.sh that sets up USB serial access.
# Download and extract the latest release
curl -sL $(curl -s https://api.github.com/repos/emaspa/wireview-linux/releases/latest | grep -o 'https://.*linux-x64.tar.gz') | tar xz
cd wireview-linux-*-linux-x64
# One-time USB serial setup (installs the udev rule)
./install.sh
# Run
./WireView2Requires .NET 8.0 SDK or later.
git clone https://github.com/emaspa/wireview-linux.git
cd wireview-linux
./install.shRun it as your own user; it uses sudo where it needs root. The install script will:
- Install the udev rule (serial port and DFU bootloader
0660 root:dialout, plus auaccessACL for the user logged in at the local seat) - Only when there is no local seat session (SSH, for example): add your user to the
dialoutgroup, which needs a new login to take effect - Build the application
Or manually step by step:
git clone https://github.com/emaspa/wireview-linux.git
cd wireview-linux
# Install udev rules (grants access to the WireView USB device)
sudo cp udev/99-wireview.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules
sudo udevadm trigger
# Only over SSH or another session without a local seat (no uaccess ACL there):
# join dialout, then log in again
# sudo usermod -aG dialout $USER
# Build and run
dotnet build -c Release
dotnet run --project WireView2/ -c ReleaseIf you just want to test without logging out:
sudo chmod 666 /dev/ttyACM0This is temporary and resets when the device is unplugged.
The app has five pages accessible from the left sidebar:
| Page | Description |
|---|---|
| Overview | Summary of total current, power, voltage, cable rating, temperatures (sensors that are not connected are hidden), and a fault status/log table with per-fault clear |
| Monitoring | Real-time charts for voltage, current, power, and temperature; custom series selection, colors, and Y scaling |
| Logging | Read device logs per power cycle and export to CSV |
| Device | Device info, full device configuration (fan, display, alarms, thresholds), display theme editor, and firmware updates |
| Settings | App theme (Auto, Light, Dark, Noctua Light, Noctua Dark; Auto follows the desktop's light/dark setting and switches to the Noctua colors while a WireView Pro II Noctua Edition is selected), startup behavior, background, and LAN settings (remote hosts, publish toggle/port, network secret, log retention) |
On the Device page, you can save the current device configuration as a named profile and load it later. Profiles are stored as JSON files in ~/.local/share/PowerMonitor/profiles/.
| Mode | VID | PID | Description |
|---|---|---|---|
| Normal | 0483 |
5740 |
STM32 CDC/ACM virtual serial port |
| DFU bootloader | 0483 |
df11 |
STM32 bootloader (during firmware updates) |
