...just a quick question... I think I already know the answer but.. just to be sure:
Domotiz runs as root user...
are Python plugin under the same rule? (so they run as root?)
what If I want to run them as another user?...is that possible?
ciao

Never, ever, run Domoticz or any other service as root. This sentence should be read at least 10 times.
That said, any process started by another process will run in the same user-context. So if Domoticz is running as userX, everything else will run as the same user. You could start, e.g. via the Python plugin, another process as another user. Maybe you have a reason to do so but I can't think of any.

My question was in regards of a plugin I'm writing and for which I'm stucked at base level...
I'm using gattlib, that must be run as root to get access to hci0 interface
the plugin doesn't run, so I was wondoering if it could be a user problem, but I assume it is not....

Well, I suppose it's running ok outside domoticz?
Just to be sure you can check from within the plugin if indeed you are running within the root context.
This is how I start (sub)processes
Code: Select all
import subprocess
prc = subprocess.run(['whoami'], stdout=subprocess.PIPE)
iAm = prc.stdout.decode('utf-8')
Domoticz.Log("I am user:" + iAm)
