It would be nice to have a feature that allows for the randomization of lights turned on or off +/- a user defined time variable. For example, having exterior lights turn on anywhere from 5 minutes prior to sunset to 5 minutes after sunset with the exact timing changing daily, giving the appearance that someone is home performing the task. Does Hubitat have this capability?
There is no built in "app" that does this but the built-in rule machine could if you created it. Alternatively there are a few custom apps on the community, that is built just for this that i would recommend. I'll find the link if your interested.
This is the one I use .
