Controls Litra Glow and Litra Beam USB conferencing/streaming lights
Solution is thanks to two existing command-line tools, which we learned from to create our own solution:
- https://github.com/kharyam/litra-driver (a PyUSB driver that doesn't work on macOS)
- https://ultracrepidarian.phfactor.net/2022/03/09/controlling-the-logitech-litra-on-macos/ (instructions for using shell functions with 'hidapitester' to control a Litra Glow)
We ship amd64 and x86_64 versions of the hidapitester binary from https://github.com/todbot/hidapitester ; the correct one should be autoselected, which means this works with both Intel and Apple Silicon M1/M2 chips
You can also use the hid-litra.py script without Alfred, but only on macOS
Use 'litra [-d {glow,beam}] [-t TEMP] [-b PERCENT] [{on,off}]'
If you specify a TEMP or PERCENT value, 'on' is presumed unless 'off' is specified.
