OpenLogi

Litra lights

Control a Litra light's power, brightness, colour temperature, and camera-linked auto-power.

OpenLogi drives standalone Litra lights over their raw-HID protocol and shows them in the same device carousel as your mice and keyboards.

Litra Glow (046d:c900) and Litra Beam (046d:c901) are recognised by their raw-HID interface. Selecting one opens a Lighting tab with:

  • Power — on / off.
  • Brightness — 0–100%, mapped onto the light's native range (20–250 lumens on a Litra).
  • Colour temperature — 2700–6500 K in 100 K steps.
  • Auto-on with camera — turn the light on while any camera is in use and off when camera use stops (macOS). The manual power choice and the other settings stay independent of this policy.
[devices."raw:046d:c900:ff43:0202:serial:YOUR-SERIAL".light]
enabled = true
auto_camera = true
brightness_percent = 65
temperature_kelvin = 4600

A light's config key is its raw-HID route plus a serial number. If the HID backend exposes only a transient OS-node identity for your light, OpenLogi won't persist settings for it; openlogi light list prints the HID tuple and identity it sees, which is the fastest way to tell.

Status: Litra control works wherever raw HID does — macOS, Linux, and Windows — with the camera-linked auto-power policy on macOS.
