How does it "work" (logics)

Hello guys.
I was wondering how the logics is done in oh… Does it scan through the logics all time, or is it event based reactions?
When I change something in the logics, what is needed to oh to run it? Is a reboot nessecary or?

Take a look here, especially the description of the Event bus.
Changes on rules, items, scripts, … are picked up automatically after a predefined time interval (default=10 seconds)
Changes to the openhab.cfg needs a restart of openhab, but you may configure this also to be picked up automatically.

Okay I understand… Meaning when I change something it will work immediately- changing items and logics…

The logics can be triggered from the console - as I read it :slightly_smiling:
