Cant you set in the means to turn off, a limit of active motion? I have done this so that if the fan turns off the lights turn off but NOT if there is active motion, then if no motion, but the fan is ON, also limited. They both have to be off and whichever one goes off last triggers the means to turn off. I have thought about also adding a timer to this for the exact reason they asked about it, I think it would work.
