It’s a module… not sure how to use it but there you go Read the docs should tell you how
It is the module I mentioned. Yesterday I thought I can not set this module up. But now it seems working.
It does not work at all. At least not the way i hoped.
so i really like to get the python-autostart working. any help?
Look into cron.
thanks so far.
i have already put this as cron: @reboot sudo /usr/bin/python /home/pi/monitor.py &
but nothing happens
when i want to start this, i will get this message:
[…] Restarting cron (via systemctl): cron.serviceFailed to restart cron.service: Access denied
So what can i do now?
@pauabaer It’s easier to just make your python code executable. Then you can just start it with cron with
- how do i make it executable?
- when the script is executable, the problem with the failure is still existing, isn’t it?
@pauabaer To make the code executable:
- Add #!/usr/bin/python3 to the top of your code.(1st line)
- open terminal and type sudo chmod +x /home/pi/monitor.py (this will make your code executable. You can check that it’s executable by typing “./monitor.py” You code should run.
Then you can add the line @reboot /home/pi/monitor.py to the crontab.
Ok. Thanks. I made these two steps and i can see via htop that the script is running.
