I'd like to have some of the lights in my house randomly turn on and off when I'm away between sunset and midnight. Does anyone have a good algorithm to do this? I've already got the "when I'm away" part working, and I have some basic lights working, I just want the best way to do it.

I've thought about doing this, but instead of being random I thought it'd make more sense to mimic my habits. So turn on the living room lights from sunset to 10pm, turn on bedroom lights from 10pm until 10:30 etc.

If you add a Wait command there is a Random option.

 

Clipped example:

If
       On Never
       Time is Last Run Time for 'Cycle Outside Lights'

Then
       Repeat Every  1 second
          Set Scene 'XBlue XMas Lights' On
          Wait  5 minutes 
          Wait  3 minutes  (Random)
          Set Scene 'XBlue and Red Lights' On
          Wait 20 seconds

Else
  - No Actions - (To add one, press 'Action')
