To avoid sensors using unnecessary battery to send reports the Nero Multi has a configurable motion timeout. This timeout is by default 4 minutes but can be changed to be anywhere from 10 seconds to an hour. During the timeout any motion detected by the sensor will re-zero the counter. This means that there must be at least 4 minutes of no motion before the sensor will send a message to the controller letting it know that the sensor has reset.
Sensor is powered up
Motion is detected
Controller is notified
Timeout after last motion
Reset sent to controller
Why is this important?
Most of the time you won’t have to think about motion timeout, however it can become a frustrating factor when trying to properly configure sensor lighting and notifications.
For example if you configured a sensor light to turn on when motion is detected and then set a 10 minute delayed action that turned it off again you may notice the light turns off when there are still people in the room. This is because the sensor hasn’t sent a new update to the controller, but the 10 minute counter on it has expired. In this case you would want to reduce the motion timeout on the sensor to a lower value or increase the amount of time a light stays on after being triggered.
