ZSE18 Motion Sensor Parameter 18

Product Support

While going through somethings, I noticed the what appears to be discrepancy?

ZSE18 Motion Sensor Advanced Settings

Parameter 18: Set motion clear time for the delay before the sensor reports no motion to the hub and associated devices after detecting the last motion activity.

From the manual:

Parameter 18: Use it to set trigger interval - the time when motion is reported again after initial trigger.

I do at times have issues with the sensors not reporting back that the motion has stopped. However I think this is another issue.

Is this Parameter 18 actually a delay between motion detection, or a delay between reporting motion? It seems like the manual is correct?

This parameter is, I believe, what some call the “cool-down period.” In other words, the time after a reported motion event where the sensor won’t report a new motion event. After that time period, it resumes reporting.

Example: it’s a holiday and your living room is full of people wandering around. Instead of hammering the hub with “motion/no motion” events, it waits until some period of no motion–set by this parameter–after which it will report a new motion event. So, eventually the family moves to the dining room for dinner and the living room goes quiet and a no motion event is sent to the hub–now the motion sensor is ready to send a motion event when a person enters the room after the meal.

Maybe I’m over thinking it. I thinking of it like the manual says, and it would give the all clear (perhaps an assumption), but would not report anymore motion until the cool down period had passed.

Perhaps this is why my motion sensors get “stuck on”, as they never send the all clear, they just go to sleep?
