How to turn lights off completely

Hello, During a wind night storm my floodlight kept turning on and off. Turning the lights off did not affect this process. I saw something about turning motion zones off, but do not find a way to do that - just change, add or delete zones. I suppose I could turn (and leave) them on to stop the disruption, but that seems a poor solution. I'd rather turn them completely off (maybe for a set time) during a storm? Thank you, Dan
