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!!!
