This would enable me to set 2 times between which a ‘random’ trigger would start.
This would be useful for security lights etc to come on and off a random times.
Olisto doesn’t have such a randomize function, or any complex math or logic functions, so you would be better off to use another service for that. I would suggest Switchur (https://support.switchur.com/). Switchur is designed to work together with other services like Olisto using incoming and outgoing webhooks, it allows complex math and logic functions, and it’s free. So you would have an Olisto trigger send a web message to Switchur, and Switchur could return a random time to Olisto.
