By default, the Hub is set to ping detectors every 36 seconds and to signal an alert after 30 undelivered pings. Under these settings, it will take about 18 minutes for the system to recognize a communication failure. You can adjust these settings by opening the app, going to the Hub Settings →Jeweller.
In additional Relay can react on arming/disarming in a pulse mode. The WallSwitch, Relay and Socket reaction is also available for “Night mode”.
