Maximum time difference in seconds allowed between the temperature and humidity values for a device. dewpoint uses the Readings for temperature or humidity if they are not delivered in the event. This is necessary for using dewpoint with event-on-change-reading. Also needed for sensors that do deliver temperature and humidity in different events like for example technoline sensors TX3TH.<br>
