Try it right here: pick a hotspot, then choose any of the built-in actions.~/.config/openlogi/config.tomlliveschema_version = 2selected_device = "2b042"[devices.2b042.bindings]MiddleClick = "MissionControl"DpiToggle = "CycleDpiPresets"Thumbwheel = "VolumeUp"Forward = "BrowserForward"Back = "BrowserBack"GestureButton = "AppExpose"MX Master 4Writes straight to config.toml — auto-switches per app.FeaturesEverything Options+ does — without the account.OpenLogi drives your mouse over HID++ directly: buttons, DPI, SmartShift and per-app profiles, from a native app that never phones home.Remap any buttonBind any of 44 built-in actions to each physical button, per device — plus custom shortcuts, app launchers and scripted actions.44 ACTIONSDPI control & presetsSet pointer resolution and cycle your own presets, written straight to the sensor over HID++.HID++ 0x2201SmartShiftFlip the wheel between ratchet and free-spin, or let it switch automatically by scroll speed.HID++ 0x2111Per-app profilesLayer per-application overlays that auto-switch the moment your focused app changes.AUTO-SWITCHBolt, Unifying, Lightspeed, Bluetooth or wiredReach devices over a Logi Bolt, Unifying or Lightspeed receiver, a direct Bluetooth pairing, or a USB cable — no receiver required.BOLT · UNIFYING · LIGHTSPEED · BLE · USBLive device viewA carousel of paired devices with battery percentage and charge state for everything online.BATTERY · CHARGELocal-firstYour mouse.

On Linux, the same applies to Solaar.FAQQuestions, answered.Is OpenLogi made by Logitech?No. It's an independent, open-source project, not affiliated with or endorsed by Logitech. "Logitech", "MX Master" and "Options+" are their trademarks.Do I have to quit Logi Options+?Yes. OpenLogi and Options+ both speak HID++ to the same device, and only one can own a receiver at a time — quit Options+ (including its menu-bar agent) first.Which mice are supported?MX Master 4, 3S and 3, MX Anywhere 3, Signature M650 and Ergo M575 — over a Logi Bolt, Unifying or Lightspeed receiver, direct Bluetooth, or USB. Keyboards get F-row remapping, Fn-lock and RGB or backlight control; Litra lights and Logitech webcams are supported too.Does it run on Linux or Windows?All three are supported. Linux ships .deb, .rpm and Arch packages with udev rules and a systemd user unit. Windows is the newest port — validated end-to-end on Windows 11 hardware, with signed .msi installers in every release.Does it need an account or send telemetry?Neither. The only network calls are device-image downloads and an opt-in update check that's off by default — everything else stays on your machine.Where are my settings stored?In a single plain-text TOML file. The GUI writes your bindings, presets and profiles to it directly, the Settings window covers app-wide preferences, and the file stays hand-editable.
