Random lights for security

What I seek is any of my seven hue lights to be randomly turned on or of, often as frequently as every other minute all day every day whilst I am away for security purposes.

I believe most burglars are opportunistic and will view your house for no more than a minute or two. Not long enough to appreciate your routine as to how you use your lights day to day. If a light goes of or on, even during the day that is a big enough question mark to make them move on.

So the question is. Can I set totally random, frequent on and off across all my seven hue lights, with an easy method of triggering on and off. (No geo fencing unless it is smart enough to recognise the absence of TWO phones, not just one.

A very big thank you in advance to anyone who has appropriate advice,
