#Clight describes itself as a "C daemon that turns your webcam into a light sensor".
My overlay has the latest v4.11 release available for fellow #Gentoo users.
See my post for links: https://blog.ferki.it/2024/05/01/packaging-clight-4-11-for-gentoo/
If you liked similar software such as Calise and Redshift, and you are looking for an actively maintained solution, setting up Clight may be a good weekend project :)
Happy hacking!

I am now a GURU contributor \o/
GURU is an official package repository maintained collaboratively by #Gentoo users: https://wiki.gentoo.org/wiki/Project:GURU
I maintain several unofficial packages in my overlay, like #Laminar, #Proselint, #Clight, #Vale, #OfflineIMAP3, #actionlint, #dive.
Having direct access to GURU allows me to publish these into an official source for the greater benefit of the wider #community.
#Clight is a light sensing daemon.
Clight captures occasional frames from webcams or readings from sensors to detect the ambient lightness. Clight then exposes these values on DBus for other programs to use the data. Clight uses modules for implementing functionality, including adjusting screen and keyboard brightness, screen gamma, etc. Clight provides an easy to use API for developing custom modules.
