The xprintidle solution from martokk is awesome, simple and very versatile… except for a tiny issue: getting SSH to run properly from the command_line integration seems to be a nightmare (sample complaint post from 2020).
- You obviously can’t pass a password via argument to ssh
- no clue if it’s ever possible to install sshpassin HA Core
- SSH keys seem to be wiped with Core updates (reply at the same post)
- I mean, if you ever figure out how to add a working SSH key; the SSH add-on don’t run at the same container which the integration will execute (reply at the same post, integration docs “hint”), so testing from the add-on and seeing it working fine makes you feel like a

Other solutions I’m leaning towards:
- edit [THIS ONE WORKED!!!] installing some sort of HTTP server on my computer and make it spit out xprintidlewhenever a given page is requested… so somehow HA can pick that up through, idk, curl? Nonetheless, that’s a lot of work which could be simply done via SSH lol- I indeed installed Apache in my computer
- I added a cronjob to store xprintidle output in Apache’s folder: crontab -e; then add*/1 * * * * DISPLAY=:0 xprintidle 2>&1 > /var/www/html/xprintidle.txt- 2-year later note: after reinstalling my OS, I lost the cronjob and tried to do it by hand, before finding this very own post. Turns out this can’t be done directly with PHP (e.g. <? passthru('xprintidle');) because that process won’t be executed by your actual user lol

- some indirect trick with System Bridge
- hope for something like HASS.Agent but for Linux lol
