I was thinking about how rules are triggered in case you have several ruleset for different things which uses Cron triggers.
When you have multiple stuff there is definitely later or earlier situation that you are using Cron at same time at various rules.
How OH is handling these? is it running all rules as one because same cron time or they are run separately?
If separately, isnt it performance killer in case you have 20 rules which runs at midnight?
just thinking about this for some unknown reason.
