Thanks - yes, I got the “steps” (not a script, I don’t think, as you have to enter each command separately) from that exact webpage. I don’t know enough about RPi / Linux to know which set of steps to use, so I used the first set (“For Raspbian / RetroPie / Twister OS v2.0.2”), which seemed to work. The /x-c1 directory was initially a subdirectory within /umbrel, but then I ran the commands again, and now I have an /x-c1 directory off of the root, next to /umbrel. [on edit: to be clear I have two /x-c1 directories, one off the root and one as a subdirectory of /umbrel]
I also ran the steps they offered for crontab (whatever that is), which I think should make the fan start automatically. But I’m really out of my depths here, learning as I go along.
The temp is now up to 85 degrees celsius, so I’m pretty sure the fan isn’t running.
I have / can see the fan.py file within /x-c1. If I “run” it, shouldn’t that start the fan? How do I do that in Linux?
UPDATE: if I cd to the /x-c1 directory off of the root, and then type
sudo python fan.py&
It asks for me to enter the password for the umbrel (by writing “[sudo] password for umbrel:”), then (after I enter the password) it says
What the heck does that mean?
Now, when I run “jobs” it gives this response:
+ Running sudo python fan.py &
