Away mode settings for lights

[bobbles (Bob)]

I have just bought a Smartthings hub to run some Belkin WeMo lights.
Through the WeMo app you could set up a rule when you are away that would randomly turn lights on and off in a predefined window to give the impression that someone is in.
I have found a rule that will turn lights on and off in a predefined window but these turn on and off at a set interval and not random intervals.
Can this be done?

Thanks,
Bob.

Yep. You’ll want to install this SmartApp:

[OBSOLETE] Vacation Light Director

Occupancy light simulator will simulate your house being lived in even when you are not. Pick a set of lights and at a interval you specify the app will turn off all lights and then turn on a random set of lights. Nice things is you can restrict this to mode/time/day of week. It is always triggered by mode change but will not run outside of specific restrictions you set. Nice things is it will not run if someone is home and the mode changes. Thanks to @dave for testing!!! https://github.com/tslagle13/SmartThings/blob/master/Director-Series-Apps/Vacation-Lighting-Director/Vacation%20Lighting%20Director.groovy

Thanks for the response.
I have just set this up but it doesn’t appear to be working.
I have the following set to test it.
SETUP
Which = Home and Away.
Switches = Just one bulb for testing purposes.
Cycle lights = 10 minutes
Number of active lights = 1
People do not change = My Android phone.

SETTINGS
Default = 1
Only between = 3:00 pm and 10:45pm
Days of week = Left Blank.

Nothing seems to be happening. I have disabled wi-fi and mobile data on my android to simulate a change of presence.

Any ideas / guidance much appreciated.
