Usage

In the background, using Homebrew Services (Homebrew installations only)

Run brew services start timrogers/tap/litra-autotoggle.

litra-autotoggle will run in the background, and your Litra will turn on when your webcam turns on, and off when your webcam turns off. If no Litra device is connected, the listener will keep on running, but will do nothing.

[!NOTE] When starting the service for the first time on a macOS device, you will receive a notification warning you about software running in the background.

From the command line

Just run litra-autotoggle. Your Litra will turn on when your webcam turns on, and off when your webcam turns off.

The following arguments are supported:

• --serial-number to point to a specific Litra device. You can get the serial number using the litra devices command in the litra CLI.
• --require-device to enforce that a Litra device must be connected. By default, the listener will keep even if no Litra device is found.
• --video-device (Linux only) to watch a specific video device (e.g. /dev/video0). By default, all video devices will be watched.

Configuring udev permissions (Linux only)

On most Linux operating systems, you will need to manually configure permissions using udev to allow non-root users to access and manage Litra devices.

To allow all users that are part of the video group to access the Litra devices, copy the 99-litra.rules file into /etc/udev/rules.d.

Next, reboot your computer or run the following commands as root:

# udevadm control --reload-rules
# udevadm trigger
