OpenOptions+

An open-source Logi Options+ alternative for Windows, built with AI assistance

Configure your Logitech mouse locally: battery percentage and charging status, DPI, SmartShift, button remapping, and application profiles.

OpenOptions+ is an independent, experimental desktop application inspired by Logi Options+. It combines an Italian-language Electron interface with a native Windows HID++ backend. Development was assisted by artificial intelligence, including Codex and REA for local application research, implementation, and testing.

Features

Feature	Current implementation
Battery monitor	Real battery percentage and charging indication when reported by the mouse
Logitech device discovery	Compatible HID++ 2 devices over Logi Bolt, supported USB receivers, or direct HID interfaces
Mouse DPI	Reads the sensor's supported values, writes only supported DPI, and checks the readback
SmartShift	Reads and changes automatic wheel shifting on compatible devices
Button remapping	Back, Forward, and middle-click: copy/paste, undo/redo, desktop, Task View, screenshot, media controls, and browser tabs
Per-application profiles	Automatically chooses a profile by the foreground executable's filename
Scrolling and pointer	Natural-scroll inversion and Windows pointer speed
Local settings	JSON import/export, local persistence, tray operation, and diagnostics

No cloud account is required. No Logitech driver, application bundle, extracted code, or original artwork is distributed with this project.

Download and run

1. Open Releases.
2. Download OpenOptionsPlus-0.1.0-windows-x64.zip from Assets. The automatic “Source code” archives are for developers.
3. Extract the entire ZIP to a writable folder.
4. Open OpenOptions+.exe inside the extracted OpenOptions+ folder.

The portable ZIP includes the Electron runtime. Node.js and npm are not needed to use the downloaded app. Keep the accompanying files next to the executable. The build targets Windows x64 and uses the system's .NET Framework 4.8; hardware testing has been performed on the development machine, not every Windows version.

The first release is experimental and unsigned. Publisher verification and automatic updates are not provided. Download from this repository's Releases page and follow your computer's software policy. SHA256SUMS.txt is provided beside the ZIP; PowerShell can calculate the downloaded file's hash with:

Get-FileHash .\OpenOptionsPlus-0.1.0-windows-x64.zip -Algorithm SHA256

First use

• Wake your mouse and click Aggiorna (Refresh). Battery readings refresh automatically every 30 seconds.
• Select the device to configure supported hardware settings.
• Open Impostazioni (Settings) to enable button remapping. It starts disabled.
• The X hides the window to the tray. Right-click the tray icon and choose Esci e disattiva le rimappature to exit completely.

Scope of input settings: button mappings and natural scrolling use a global Windows mouse hook and apply to all mice, including non-Logitech mice. Windows pointer speed is also global. DPI and SmartShift are device settings. Hardware and Windows pointer-speed changes can remain after closing the app; hook-based actions stop when the app exits. Imported profiles do not silently enable the hook.

Compatibility and current limits

Hardware verified: Logitech MX Master 3S through a Logi Bolt receiver. Real battery percentage, charging state, DPI values, and SmartShift state were read. Writing the existing DPI value and reading it back was verified. This is not a claim of compatibility with every Logitech mouse.

Other HID++ 2 devices may expose different features. Unsupported or unreadable controls are disabled. A sleeping device may require physical movement and Refresh. Logi Options+ running at the same time can compete for settings; avoid configuring the same mouse in both apps simultaneously.

Not implemented in this version:

• Logitech Flow / multi-computer control
• Smart Actions or custom macros
• Receiver pairing and firmware updates
• Keyboard key remapping or backlight configuration
• Proprietary gesture-button diversion
• Cloud backups and automatic updates

Keyboards can be discovered and may report a battery level, but this version configures mouse controls. Windows can block injected shortcuts into applications running with higher privileges. The UI is currently in Italian; translation contributions are welcome.

Build from source

Requirements: Windows x64, Node.js 24 LTS (24.11+) with npm, and the .NET Framework C# compiler installed with Windows/.NET Framework 4.8.

git clone https://github.com/Kibra2025/OpenOptionsPlus.git
cd OpenOptionsPlus
npm ci
npm run install:runtime
npm run build:native
npm start

Build the same portable layout and ZIP used for Releases:

npm run package
npm run archive

Output: dist/OpenOptions+/ and release/OpenOptionsPlus-0.1.0-windows-x64.zip. A release archive is refused if the portable output contains user data.

npm run test:syntax
npm test
npm run test:native
npm run test:desktop

The first three commands do not change device settings. The desktop smoke test uses isolated profiles and briefly enables a pass-through mouse hook; it also writes back the current Windows pointer speed. See verification notes and contributing.

How it works

Electron renderer → isolated preload API → main process → C# helper
                                                        ├─ Windows HID / HID++
                                                        └─ Windows mouse hooks

• renderer/ — local UI and original SVG device illustrations
• app/ — Electron lifecycle, validated IPC, and JSON persistence
• native/LogiBridge.cs — HID discovery, HID++ feature requests, and input handling
• scripts/ — build and release packaging

The renderer runs with context isolation and sandboxing. It cannot access Node.js directly. The app uses feature discovery and device replies rather than fabricated demonstration devices. Local profiles and Chromium data are created in data/ next to a portable executable; they are excluded from this repository and release assets.

AI-assisted development

This project was created with substantial AI assistance. REA was used for static research on a locally installed application; that research had incomplete coverage. OpenOptions+ is an independent implementation, not a full reconstruction of Logi Options+ or its native driver. Public protocol references, including Solaar's HID++ documentation in source, informed the wire-format implementation.

AI-generated code and successful smoke tests do not establish correctness on all devices. Reproducible bug reports, hardware compatibility reports, code review, and tests are welcome. See third-party notices.
