How to add randomness to an away lighting schedual (OPEN)

[Sharpy (Aaron Sharp)]

hi everyone i’m planning on setting up a lighting schedual for when i’m away from home how would you get it to happen on a randomish time so that the lights wouldnt come on and go off at exactly the same time of day

Simulate presence by randomly switching lights - any rules existing?

All, I am looking for a rule to randomly switch lights in the evenings to simulate presence. In the timeframe between sunset and e.g. 11 pm check a random value and in case of … switch on a light for n minutes, with n between 10 to 30 minutes randomly. And repeat that again and again until 11 pm. Any idea or rule already available ? Thanks in advance
