[SOLVED] Help understanding rules

[Dim (Angelos)]

@Mobyn1ck

Does the loginfo just log values for review or are they used in the code later?

Just logging (into openhab.log)

@Mobyn1ck

Is the GoToSleep a reference to the rule name?

It is just a String for the loggerName that can be used to identify the entry in the logfile.

@Mobyn1ck

Where does the “Starting” and “Finshed” reference to?

Just a string that is used to for the log message.

@Mobyn1ck

while these two perimeters are met then change colour and brightness by said amount which i am assuming will loop until the 30000 sec is up unless the below variable are met first thus closing the the code.

(almost) correct
The while loop will run until percent >0 (and scene is 9)
It works like this: Starting from 100%, we drop -5% every 30 secs
It will take 20 steps to go down to 0%, so: 20*30secs = 10 mins

Important Note: Thread::sleep(30000) (or 30 secs) is not recommended.
another (better) way would be: createTimer(now.plusMinutes(x))
