Ok, follow up question about the above outside lighting program and the From, To command.
Does the From Sunset command run the 'Then' portion of the program only if it is in the 'enabled' state at the time specified?
For example, let's say the program has been disabled. Sunset occurs at 5 pm and then at 5:10 the program is enabled.
(Scenario I) Does the program then evaluate the 'If' condition and say to itself (if programs could talk):
"oh, it is between Sunset and Sunrise, so I will execute the 'Then' condition and turn on the Exterior Lights."
(Scenario II) Or, does the 'From Sunset' command act as a reminder: "Remember to turn on the Exterior Lights at Sunset". But if the program is disabled at Sunset, that reminder goes away and the program will do nothing until the next reminder comes up (Sunrise).
I think Scenario II is the answer and I just have to get used to the fact that the ISY programming language is a little different than other languages that use similar syntax.
So the program is really doing this:
If Current Time = Sunset, then run 'Then' commands
If Current Time = Sunrise, then run 'Else' commands
Thanks for helping me get this sorted out.
