By default, the hub is set to a hub–detector ping interval of 36 seconds and 30 undeliverable data packets to consider the device lost. With these settings, the hub will detect the loss of the detector in 18 minutes.
To reduce this time, go to the hub settings
The time before raising the alarm by the communication loss between hub and device is calculated with the following formula:
Detector Ping Interval × Number of missed pings to determine connection failure
Note that with the minimum ping interval, short-term interference can lead to loss of connection with the device. Therefore, set the minimum values only if it is critically important to promptly inform about events in the system.
