hi, i have the same problem, how did you solve it?
Hi, this takes the writing off my screen but the backlight stays on
Great. Worked for me too. Thanks so much for sharing!
not working on my Dell laptop as well
i am using old dell laptop running hassio, it says no directory found
So, I have the same issue. I’m running on an old lenovo convertable that uses eMMC.
However, you can, on boot edit grub (press e). This allows me to blank the screen but not power it down.
Appropriate hardware is tricky.
I want to go with this solution to programmatically turn off or dim my Laptop since recently there has been a massive advancement in using the laptop screen as a dashboard.
I’m running HAOS but whenever I try to run this automation via the call_service it responds with Event fired successfully but NOTHING happens. Trying from the Advanced SSH addon yields a similar result with an error:
tee: /sys/class/backlight/intel_backlight/brightness: Read-only file system
Plugging in a keyboard works, but that option kinda sucks. Any ideas as to why Home Assistant cannot run this as an automation? With the keyboard plugged in I’ve made sure to touch the file with a chmod, giving it maximum permissiveness.
UPDATE: I got it to work, it turns out call_service has been depreciated and replaced by perform action. Thank you, works like a charm!
Hi Blues. I did everything as you wrote but at the end of editing i was not able to save it. “w” was not working. The key simpli didnt work , but “q” did. Is it might be read only? Can you please help how to save the change?
THank you
