Dusk dawn question
« on: January 24, 2018, 04:54:51 PM »

I see that timer programming includes dusk/dawn settings. Does this also allow for offsets to the dusk/dawn times? Thanks.

Since this ended up becoming a bug thread I split the thread and moved it to the Bug section

Dusk:  Does -30 mean if the sun sets at 6:00 pm the devices are turned on/off at 5:30 pm?  (+30 6:30 pm)?
Dawn: Does -30 mean if the sun rises at 6:00 am the devices are turned on/off at 5:30 am? (+30 6:30 am) ?

It is randomized with the randomizing window; plus or minus, UP TO thirty minutes from the set time, or from the calculated dusk/dawn times.

Not sure that I agree with this.  When I set offset times, my lights turn on relative to sunset times.  If I set the offset to -5, the light turns on 5 minutes before sunset...not dusk.  Perhaps I am confused.

BTW, do not mix sunrise/sunset and dusk/dawn terminology. They are completely different.  For instance, civil, nautical, and astronomical dusk times occur AFTER sunset!

No, I think I am.
ceedee's question implied the offset was exactly 30 minutes (or what was set as the offset). I was trying to clarify that the offset is a randomized amount within the set offset limits.

My understanding is that any randomization is related to the "security" function.  That said, the "randomness" of the security function leaves much to be desired.  My comments on this are in another thread.
