I use a rule-based automation in OpenHab (similar to HA) to randomly pick a light from a group and toggle it after a random interval, and it repeats the process every 10 minutes from 4pm to 11pm. I find this better than relying on prior history since there is no guarantee that my prior pattern of occupancy would be applicable to a vacation period. Better to just randomly cycle random lights - that will confuse them ;-)
