CleverSwitch

A small, headless, cross-platform daemon that synchronizes host switching between Logitech keyboard and mouse. When you press the Easy-Switch button on the keyboard, CleverSwitch detects it and immediately sends the same host-switch command to the mouse — so both devices land on the same host simultaneously.

• Runs alongside Logi Options+ or Solaar without conflicts.
• Must be installed on every host you plan to switch from.
• Currently supports connections via Logitech receivers and Bluetooth.
• Tested with MX Keys and MX Master 3 on Linux, macOS, and Windows.

CleverSwitch does not override device firmware. It acts as a forwarder, which means there is a small delay after reconnection. If you switch back immediately after arriving from another host, the devices may not switch together — CleverSwitch needs a moment to set everything up after reconnection. Especially on Bluetooth. But it mostly depends on the BT version.

Installation

macOS

1. Clone the repository (or download the sources archive from Releases).
2. Open Terminal and navigate to the project folder.
3. Run:

chmod +x scripts/mac/setup.sh
./scripts/mac/setup.sh

The setup script will install Homebrew (if needed), Python, hidapi, and CleverSwitch itself. It will also ask whether you want CleverSwitch to start automatically on login.

On first run, macOS will prompt for Input Monitoring permission. If no prompt appears, grant it manually:

1. Open System Settings > Privacy & Security > Input Monitoring.
2. Click the + button.
3. Press Cmd + Shift + G and paste the path to your binary (e.g., /your/path/cleverswitch).

Use which cleverswitch to find the path.

Windows

1. Download cleverswitch.zip from the Releases page.
2. Extract the archive.
3. Add the location of cleverswitch.exe to PATH (optional, but preferred).
4. Run setup_startup_windows.bat if you want the app to start automatically. If step 3 is skipped, the script and executable must be in the same directory.

Linux

1. Clone the repository (or download the sources archive from Releases).
2. Open a terminal and navigate to the project folder.
3. Run:

chmod +x scripts/linux/setup_linux.sh
./scripts/linux/setup_linux.sh

The setup script will check for Python 3 and hidapi, install CleverSwitch, set up udev rules for non-root HID access, and optionally create an autostart entry.

From Sources

Requires Python >=3.10 on PATH.

1. Clone the repository.
2. Install:

pip install .

3. Run:

cleverswitch

Windows note: The hidapi DLL must be downloaded manually and placed in a directory on your PATH.

Linux note: Install udev rules to allow non-root HID access:

sudo cp rules.d/42-cleverswitch.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && sudo udevadm trigger
# Unplug and replug the receiver

macOS note: On first run, macOS will prompt for Input Monitoring permission (see macOS section above).

Homebrew

Will be available once the Homebrew formulae criteria are met:

• be known (e.g. GitHub repositories should have >=30 forks, >=30 watchers or >=75 stars)
• be used by someone other than the author

Run on Startup

macOS

Handled by setup_mac.sh during installation. To set up separately:

chmod +x scripts/mac/setup_startup.sh
./scripts/mac/setup_startup.sh

Windows

1. Place setup_startup_windows.bat in the same directory as cleverswitch.exe (unless it's already on PATH).
2. Run setup_startup_windows.bat.

To verify, open Task Manager and look for cleverswitch.exe in the Details tab.

Linux

Handled by setup_linux.sh during installation. To set up separately, use your distro's autostart mechanism (e.g., GNOME Tweaks, KDE Autostart) or see other methods.

Uninstall

macOS

chmod +x scripts/mac/uninstall.sh
./scripts/mac/uninstall.sh

This stops and removes the launch agent (if configured) and uninstalls the CleverSwitch package.

Linux

chmod +x scripts/linux/uninstall_linux.sh
./scripts/linux/uninstall_linux.sh

This removes the autostart entry, uninstalls the CleverSwitch package, and optionally removes udev rules.

Windows

1. Delete the cleverswitch folder.
2. Remove the startup entry: open Task Manager > Startup tab, find cleverswitch, and disable/delete it.

From Sources

pip uninstall cleverswitch

Configuration

Will be available in later releases.

Hook Scripts

Will be available in later releases.

Relation to Solaar

CleverSwitch is inspired by Solaar and uses the same HID++ 2.0 protocol knowledge, but is an independent, minimal implementation. It does not import or depend on Solaar.
