Announced one year ago was KDE Internet of Things “Kiot” with an emphasis on providing nice integration between the KDE Plasma desktop and Home Assistant for handling open-source home automation. Development on Kiot sadly fell through the cracks for most of the year but development on it recently restarted.
KDE developer David Edmundson shared that Kiot development has recently been restarted thanks to contributions from new developer Odd Østlie. Odd has been working on new features around Bluetooth, audio device handling, battery state handling for different devices, media mplayer / MPRIS connection, and more.
The main idea is that the state of your computer/desktop is known to home assistant and you can react to it. Media starts playing on PC, so mute the tv. A meeting starts (camera in use), so dim room lights and turn on the ring light.
PC turned off: wait 30s, then turn off the whole outlet to act as a master/slave power strip and save power on monitors and otherpc associated standby devices. Or just turn off desk lights.
Finally you can have scripts on the PC that do whatever you want, and you can trigger them from home assistant. Movement detected in the garden, so open the camera preview on the corner of 3rd monitor. Backup server just came online (or was woken up by wake-on-lan from ha), so run a backup if the PC is on.
