v1.0.6.0

New

• Power in the system tray — an optional second tray icon shows the live total power as plain text (e.g. a big "180" over "watt"), or a red icon when the device is disconnected. Right-click it for a dropdown of every live sensor value (per-pin voltage / current / power, totals, temperatures, cable rating).
• Toggles for the power icon and the unit label, available both in Settings and in the app icon's tray menu.

Notes

• The tray icons use the StatusNotifierItem protocol. On GNOME a tray / AppIndicator extension is required to see them.

Install

Precompiled binary

The tarball is self-contained (app binary + udev rule + one-time install.sh):

tar xzf wireview-linux-1.0.6.0-linux-x64.tar.gz
cd wireview-linux-1.0.6.0-linux-x64
./install.sh          # installs the udev rule (grants serial access, no logout needed)
./WireView2

Ubuntu 24.04 LTS / 26.04 LTS (PPA)

sudo add-apt-repository ppa:sparvoli/wireview-hwmon
sudo apt update
sudo apt install wireview-linux

Ubuntu / Debian (.deb)

sudo apt install ./wireview-linux_1.0.6.0_amd64.deb

Fedora (COPR or .rpm)

sudo dnf copr enable emaspa/wireview-linux && sudo dnf install wireview-linux
# or, the standalone RPM (works on Fedora 42/43/44):
sudo dnf install ./wireview-linux-1.0.6.0-1.x86_64.rpm

Arch / CachyOS / EndeavourOS (AUR)

paru -S wireview-linux-bin   # prebuilt, tracks the latest release

A community source package, wireview-linux, also exists but may lag behind.

Flatpak (Bazzite / Silverblue / immutable distros)

flatpak install ./wireview-linux-1.0.6.0-x86_64.flatpak
flatpak run io.github.emaspa.WireViewLinux

The 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/v1.0.6.0/udev/99-wireview.rules -o /etc/udev/rules.d/99-wireview.rules
sudo udevadm control --reload-rules && sudo udevadm trigger

---

The udev rule (installed by every native package, the tarball's install.sh, or the host step above for Flatpak) grants serial access directly via MODE=0666 + a logind uaccess ACL — no group membership or logout required on a normal desktop session.

v1.0.4.4

Fixes

• GUI startup crash on systems without a resolvable default font (#2) — the Inter font is now bundled directly as a project asset under WireView2/Assets/Fonts/ and referenced via the avares:// URI scheme, so font resolution no longer goes through the platform default-font path that fails on Ubuntu 25.10. FontManagerOptions.DefaultFamilyName is set explicitly. The Avalonia.Fonts.Inter NuGet dependency is gone.
• App preventing system shutdown / logout (#1) — the close-to-tray handler was vetoing OS-driven close requests during a session end, which session managers reported as "App is preventing shutdown". It now only swallows the close when the user explicitly clicks the window's X; ApplicationShutdown / OSShutdown close reasons pass through so the app exits cleanly.

The bundled Inter font is licensed under SIL OFL 1.1.

v1.0.4.3

Fixes

• GUI startup crash on systems without a resolvable default font (#2, second attempt) — the previous fix in 1.0.4.2 only registered the bundled Inter font; Avalonia was still calling the platform default-font lookup which fails on Ubuntu 25.10. This release explicitly sets FontManagerOptions.DefaultFamilyName so $Default resolves to the bundled Inter font, bypassing platform font discovery entirely.

v1.0.4.2

Fixes

• GUI startup crash on systems without a resolvable default font (#2) — Avalonia was hitting Could not create glyphTypeface. Font family: $Default on fresh installs (e.g. Ubuntu 25.10). The app now registers the bundled Inter font as the default, so startup no longer depends on fontconfig resolving a system default.
• App preventing system shutdown / logout (#1) — the close-to-tray handler was vetoing OS-driven close requests, which session managers reported as "App is preventing shutdown". Close-to-tray now only triggers when the user explicitly closes the window; OS shutdown / session-end requests pass through.

v1.0.4.0

What's New

• Config V3 support: Full support for config version 2 (UiConfigStructV2) — ARGB theme colors, background/fan bitmaps, display inversion
• Config version detection fix: Reads actual config version from device instead of guessing from firmware version
• Theme preset system: 6 Thermal Grizzly presets (TG1–TG6) + Custom, with auto-detection when loading config
• Close-to-tray: Window hides on close instead of exiting — reopen from tray icon
• Performance optimization: Chart axis updates are paused when the window is hidden/minimized
• AutoStart sync on startup: App syncs its auto-start setting with the OS state at launch

v1.0.3.2

Bug fixes

• ReadExact: Fixed Environment.TickCount wrap-around causing spurious timeouts after ~24.9 days of uptime. Replaced with TickCount64.
• SendData, WriteConfig, SpiFlashReadBytesAsync: Serial port is now always closed on exception via try/finally. Previously, a timeout or IO error mid-operation would leave the port open, hanging all subsequent operations.

See v1.0.3.1 and v1.0.3.0 for previous changelogs.

v1.0.3.1

Bug fixes

• DeviceLogParser: Fixed inverted switch logic that could cause unknown datalog entry types to be incorrectly processed instead of skipped (matches original upstream behavior)
• WriteConfig: Added offset bounds check to prevent silent byte truncation for configs exceeding 255 bytes
• HwmonDevice: Added socket response length validation (max 1024 bytes) to prevent memory exhaustion from malformed daemon responses
• HwmonDevice: Added config version validation before unmarshaling — unknown versions now return null instead of blindly deserializing

See v1.0.3.0 for the full hwmon + daemon integration changelog.
