I've just gone through the migration from ISY994i to eisy which like many folks has been non-trivial, especially around Z-Wave.

I'm almost back to where I was before the migration, but one nagging problem, at least with 5.6.4 is that Sunset/Sunrise programs just lead to positive results at any time of day (meaning the lights come on):

If
    From Sunset + 1 hour
    To    Sunrise - 30 minutes (next day)
And (
   'Outside / Front Yard / Porch Sensor' is switched On
  Or 'Outside / Front Yard / Front-yard Sensor' is switched On
)

Then
  Set 'Outside / Front Yard / Front Yard Lights' On 100%

Else
 - No Actions

Changing the If statement to a specific timeframe solves the issue (albeit poorly):

If
   From 7:05:00PM
   To  7:05:00AM (next day)

Obviously, I've checked the time settings and zone settings (and DST) and everything seems set correctly.  

So I don't know if this is a bona fida bug, or if the logic interpretation changed somewhere between ISY994i and eisy versions.

One note - I did have to edit the device statements in my programs as many of my Z-Wave devices had to be completely deleted and reinserted into the network, so not sure if they would have worked after migration if I hadn't touched them.

I'm on 5.6.4 and all my sunset / sunrise programs work as expected. Try setting your sunrise and sunset values again and then save the program.

Interesting.  I have been pulling my hair out trying to figure out why this won't work.  The light comes on all the time day or night.  

 

But my very simple on at sunset off at sunrise works fine:

 

As a follow up to this thread...I realized I was on 5.6.0.  I updated and rebooted and now my new Sunset to Sunrise issue went away.

My issue finally went away when I upgraded to 5.7.0 and it behaved exactly as it did on the ISY994i.
