Understanding Aqara Motion Detector and Detection Interval

I have an Aqara Motion detector that has a configurable Detection Interval of 10 seconds to 3 Minutes. I am not sure what the purpose of this Detection Interval is or how to utilize it in automations.

I am assuming that the Detection Interval is the amount of time that the Motion Sensor will report “DETECTED” before it goes to “CLEAR”. If that is true then if you have an automation that switches a light off 10 minutes after the Sensor reports CLEAR, then you actually have to add the Detection Interval + the Automation time (10 minutes) to get the actual time your light will stay on with no movement?

For instance if I have a motion detector with a set Detection Interval of 3 minutes and I have an automation that turns the light off 10 minutes after the motion detector turns CLEAR then the light is going to stay on for at least 13 minutes, correct? Or am I thinking about this Detection Interval all wrong?

Kind of confused…

No, you have it perfectly right. The automation will only start counting from the moment the sensor goes back to clear. If you want it to turn off the light 10 minutes after movement is detected, then you need to change the 10 to 7 minutes in your automation

I tend to set these kinds of things to the lowest interval I can that doesn’t generate too many false positives so that I can do all the delay time logic in Home Assistant. For me it’s a lot easier to setup a Number helper that is the delay is seconds I want and then use that in automations then it is to try and remember what the delay is at the device.
