I currently have some light that turn off after a specified amount of minutes via a trigger to run a wait macro. I would like to only have this trigger run the macro during day light hours. Can someone help me with the Syntax that is needed at the end of the trigger line to control this? Thank you for your help.

You mean like IF (NOW() < RELATIVETIME( 00:00:00, [SUNSET] ) AND NOW() > RELATIVETIME( 00:00:00, [SUNRISE] ), 1, 0)

When I have a trigger that I only want to run at certain times, I've been using timed events to turn them on and off. I've seen this alternate approach and understand how it works, but it raises a question for me.
Using this model (with Boolean control), technically the trigger is "firing" and processing; it's just not executing certain actions based on criteria that are not being met. But that means that PH is listening for the trigger event.
The approach I take means that the trigger is actually turned off, and therefore represents no additional load or processing requirements for PH or the Insteon network.
Does it matter? Is it worth even thinking about? Is the "cost" of leaving the trigger on and just using Boolean logic to decide whether or not to act a trivial impact on the system?

I am trying to use the code you gave in conjuction with another if statement... does this look right.
if([TEMP4]>3,1,0) and (NOW() < RELATIVETIME( 00:00:00, [SUNSET] ) AND NOW() > RELATIVETIME( 00:00:00, [SUNRISE] ), 1, 0)

How does this look
if([TEMP4]>3 and (NOW() < RELATIVETIME( 00:00:00, [SUNSET] ) AND NOW() > RELATIVETIME( 00:00:00, [SUNRISE] ), 1, 0))
Not knowing where TEMP4 will get its value from the Trigger should fire if the conditions are met.

One would think the overhead would be minuscule. Using Process Explorer I have seen virtually no system activity while PH was idle waiting.
