Edit the tasks configuration parameters in tasks_config.json.

To avoid overlapping cron job execution, use flock in crontab:

*/5 * * * * /usr/bin/flock -w 0 ~/cr1000_pi.lock python3 ~/CR1000-pi/main.py

To check if your cron job is running:

grep CRON /var/log/syslog

To make sure that flock works:

flock -n -x ~/cr1000_pi.lock true || echo "LOCKED"
