I searched and searched, and I know it's got to be here somewhere, but I can't find it!
I am looking for a simple way for a macro to only trigger (based on a motion detector) if it's dark outside (after dark, before sunrise).
I have a MS13a that I want to put in my garage. At night when I drive in, it will see the headlights (and the light from the garage door opener) and send a "light" status. I want to turn on certain lights in the house, but only if it's dark outside.
Thanks!

Welcome to PH!
One way would be to create two timed events to alternately set a flag to "dark" or "light" and then enable/disable the trigger.
Create a Global Variable, call it "SUN STATE". Create a Timed Event, set the "Timing" to "Dusk", make it a formula, and enter ph_setglobal_s( "SUN STATE", "dark" ). Create another Timed Event, this time set it to "Dawn", and make the formula ph_setglobal_s( "SUN STATE", "light" ).
Now, set the Boolean field for the trigger to be if( "{SUN STATE}" = "dark", 1, 0)
Another way would be to compare the current time to [DAWN] and [DUSK] and enable the trigger that way in the Boolean field.
