I've created a cron job and it does seem to be running. This is the line I've put in cron file :

@reboot python /home/pi/Pimoroni/bme680/Indoor-Air-Quality-MQTT.py &

I ran the command grep CRON /var/log/syslog to get the list of cron tasks :

Dec  6 13:24:54 TBHPowerPaintPlant cron[327]: (CRON) INFO (pidfile fd = 3)
Dec  6 13:24:54 TBHPowerPaintPlant cron[327]: (CRON) INFO (Running @reboot jobs)
Dec  6 13:24:54 TBHPowerPaintPlant CRON[380]: (root) CMD (python /home/pi/Pimoroni/bme680/Indoor-Air-Quality-MQTT.py &)

The script itself contains a line to log to a file when it first runs and this log file is also empty. The script runs fine from the command prompt using python /home/pi/Pimoroni/bme680/Indoor-Air-Quality-MQTT.py Can anyone tell me what I need to do to this script to run on boot up?

Thanks

    The script probably has a different home directory (possibly /root), You need to make sure that your script and any software it uses has the full path specified to any files/programs it uses.

  • So it should be python /root/home/pi/Pimoroni/bme680/Indoor-Air-Quality-MQTT.py?

  • No. You need to google linux paths and understand the difference between absolute and relative paths.

  • From my understanding, home/pi is the user folder and is the full path? Should i move the script to another location to make sure. Is there a recommended location for running scripts on system startup?
