Hi
changing the cron expression didn’t change anything but it seems that your log which mentions QuartzSchedulerThread gave me the right hint. I remembered something related to the quartz thread count when setting up caldav binding for openhab 1. I gave it a try and changed the quartz thread count to 20 and now I can see the cron rule to be triggered.
Thanks for all your help.
BTW: Is there an easy way to reset logging settings to the defaults for everything?
