LogiLockLED

LogiLockLED is a specialized application that manages the LED lighting of Logitech devices. The software allows adjusting colors, lighting effects, and synchronization between compatible devices. It supports models of keyboards, mice, and other peripherals from the Logitech brand. The configuration is applied directly to the hardware and persists after the application is closed.

• Individual color control. Allows assigning specific colors to each compatible LED zone of the device. Customization is done via palette selection or hexadecimal RGB values. Changes are visualized in real-time before final application.
• Predefined lighting patterns. Includes breathing modes, color cycle, wave, and pulse. Each pattern offers adjustable parameters such as speed, direction, and intensity. Effects work in a coordinated manner across all connected devices.
• Cross-device synchronization. Coordinates lighting between multiple Logitech peripherals connected to the same system. Maintains color and effect consistency across different products. Works with G-series devices and other compatible models.
• Brightness modification. Adjusts the light intensity of the LEDs from minimum to maximum level. The control works for both static and dynamic modes. Includes progressive dimming via slider controls.
• Configurable profiles. Allows creating and saving custom configurations for different uses or applications. Profiles are stored locally in JSON format. Includes options for importing and exporting configurations.
• Command-line interface. Provides control via terminal parameters for automation. Supports scripting and remote command execution. Includes complete documentation of syntax and parameters.
• Automatic device detection. Identifies Logitech peripherals connected to the system without requiring additional drivers. Displays model, LED capabilities, and connection status. Updates the list in real-time when new devices are connected.
• Firmware updates. Checks for and applies firmware updates for compatible devices. Maintains a local database of versions and changelogs. Includes a safe mode for recovery from failures.
• Portable mode. Runs without installation from a USB drive or local folder. Does not write values to the Windows registry. Stores configuration in a local file within its directory.
• Status notifications. Displays visual confirmations for applied configuration changes. Indicates communication errors with devices. Provides specific error codes for diagnosis.
• Cross-platform compatibility. Works on Windows 10 and Windows 11 systems. Supports 32 and 64-bit architectures. Includes an experimental version for Linux via a compatibility layer.
• Optimized resource consumption. Uses minimal CPU percentage during normal operation. Frees up resources when running in the background. Does not interfere with games or intensive applications.

LogiLockLED was created in 2022 by infra223 as a personal utility to control Logitech devices. The initial development used Python with custom libraries for HID communication. The first public version was released on GitHub in January 2023. The code is actively maintained with monthly updates.
