Could someone please help me with a rule?

If you're only ever going to be turning "night lights" on, then you could use the built-in "Enable auto off" preference in the Hubitat virtual switch to toggle back to off in the specified amount of time after it turns on. As it is a virtual switch, unless you have a Rule or other app that reacts to this switch turning off, this would not have any effect on the physical state of the lights or zbmini.
