Unlock Ubuntu as automation trigger

[broyuken1 (Broyuken)]

I am running home assistant core I think (whatever hassio is now) on a pi. My main PC runs Ubuntu and I have a light strip behind the monitor. I’d like to turn on the light strip whenever my PC is unlocked. How can I use the locked/unlocked status of Ubuntu to trigger an automation in HA?

Home Assistant Core is Home Assistant running in a python virtual environment. Hassio became ‘Home Assistant OS’.

[Linux, Gnome] Retreive the lock or unlock state of your linux computer

Hello there. I’m working on my room occupancy project, and because i rarely move when i’m at my computer, i wanted to get data on when i’m using it. First i used a simple ping, but the horrible trust is that i leave my computer running most of the time. So i went instead for something who could tell if i’m actively using it. I found that Gnome send dbus signal when the screensaver is enable, and when that happens my computer auto-lock So i’ve written a dirty python script, set it up as a sys…

I’ve not tried this, but the idea from the links below is that Ubuntu’s dbus subsystem run the shown script on lock or unlock, in this script run the hass cli utility showing in the 2nd link below to turn the light on or off, depending on if screen is locking or unlocking.

Good hunting!
