SwitchBot Contact Sensor "Motion Detected" and "No Motion Detected"

This article explains the logic behind the recognition of "motion detected" and "no motion detected".

(1)"Motion detected."

When a user enters a detection area that has detected "no motion detected", the SwitchBot Contact Sensor will immediately recognize "motion detected". Any scene or automation that uses "motion detected" as a trigger condition will be triggered and executed immediately.

(2)"No Motion detected."

To prevent malfunction, false alarms, and false detections, the Contact Sensor does not immediately recognize "no motion detected" when the user leaves the detection area.

When no motion is detected for 30 seconds, the Contact Sensor will determine and recognize "no motion detected". Any scene or automation that uses "no motion detected" as a trigger condition will be triggered and executed.

For example:

1, Contact Sensor: "No motion detected" at 13:00:00
User: Enters the detection area which was recognized as "no motion detected" at 13:01:00
2, Contact Sensor: Recognizes "motion detected" at 13:01:00
User: Leaves the detection area at 13:05:00
3, Contact Sensor: Recognizes "no motion detected" at 13:05:30
