Hey,
bin jahrelanger FHEM-Nutzer, aber eins habe ich immernoch nicht kapiert: Was ist der genaue Grund, warum man Semikolons verdoppeln muss?
Danke!

ZitatMultiple FHEM commands are separated by semicolon (;). In order to use semicolon in perl code or shell programs, they have to be escaped by the double semicolon (;;). See the Notes section of the notify chapter on command parameters and escape rules.
E.g. the following first command switches Lamp1 off at 07:00 and Lamp2 immediately (at the point of definition), the second one switches both lamps off at 07:00.
define lampoff at 07:00 set Lamp1 off; set Lamp2 off
define lampoff at 07:00 set Lamp1 off;; set Lamp2 off
For every further indirection you need to double the semicolons:, e.g. to switch on every day 2 devices at 7:00 for 10 minutes you have to write:
define onAt at 07:00 set Lamp1 on;;set Lamp2 on;; define offAt at +00:10 set Lamp1 off;;;;set Lamp2 off
Don't dispair, the previous example can also be written as
define onAt at 07:00 set Lamp1,Lamp2 on-for-timer 600
Ja, aber ist das eine Perl-Spezialität oder liegt es an FHEM?

Also ist FHEM wohl die Antwort auf Deine Frage. FHEM ist in Perl geschrieben, also ein "level" höher.
