It would be great to add a random scheduler option within smart action automation.

As an example you set a time for lights to turn on or off, but add an option to randomize that time +\- the time by XX minutes/hours and not be a static entry for on/off.  This option would address when away and you want lights to appear on and off to look like someone is home and no pattern found in the lighting.  I.e. security feature.  

Taking that idea further you create a "group," of lights and they turn on/off randomly to show up as someone moving around the house. If living room turns off, bedroom turns on. And those are timed and randomized as well.

Another option would be the app or hardware is familiar with local sunrise and sunset data and day light savings time if so followed. So if I set the lights to turn on at 7pm/19:00 and it's summer, it would still be sun-out in my area till after 9pm. Accommodate for that. But in the winter sunset is as early as 4pm and it would be dark for 4+ hours before the lights automatically turned on.  There is a great marketing message to sell here with this feature around intelligence and power savings based on local sunrise/sunset data.

I should add I'm using the smart actions within the deco app and not the Kasa app.  I see the sunrise/sunset options and relay options available in the Kasa app, but no randomized time option in either and no delay options within the deco app. The two apps don't have the same consistency between features
