@larryg,

I think that the concept is that the Away Mode shows activity in the house as if someone was home. While the lights would turn on at night, it would be far less often due to people sleeping. 

I do see how it could be useful to have the overlap, especially for those who work night shifts, so I will forward the feedback that the "Start and End Times Must be on the Same Day" is fairly limiting to the feature.

For now, you would be best suited to use the Scheduling Feature to turn the lights on/off at different times throughout the night.

  @larryg,

I'll see what our team can dig up about the specifics, as I am pretty sure I have only seen that it is random - and I have not seen the parameters that guide it.

I know that for features that exist onboard, such as scheduling and away mode, it can be harder to get a feature implemented later down the line, but I have passed the feedback on.

I believe that the feature is more designed for around sunset when lights would be actively going on and off throughout your home; but the feature exists across a variety of product lines, so while a lamp may be harder to see, a light switch can often be seen from the street. such as if you went on vacation and you wanted your kitchen lights to turn on periodically.
