Adding Home Automation to KDE
The machine you're in front of all work-day has an awful lot of useful information that can be useful in your home management.
I have a script lower my blinds if I turn on the camera during the afternoon as otherwise there's an annoying glare. My office lights and monitor both have a redder hue at night, but disabling night-mode on my PC automatically disables the main light performing redshift too. I want my screen to turn off not 10 minutes after activity, which is simultaneously both annoyingly too long and too short, but the moment the motion sensor in my room says I've left.
Home Assistant, the best open source home automation tool out there supports all of this, but it needs some hooks for the PC to tell it about the current state and invoke actions on the PC.
None of the existing solutions worked well for what I wanted. I wrote something for personal use a few years ago that worked great for me, I ran it in the background and didn't plan to take it further. During the KDE Goals sprint another user suggested creating something very similar (https://phabricator.kde.org/T17435). That goal may not have been chosen, but it did motivate me to tidy up and document what I had and turn it into a more fleshed out project.
