ADVANCED SENSOR CONFIGURATION FOR TEMPERATURE/HUMIDITY SENSORS
Fields in above screen:
Š Units: Changes units from °C to °F or vice versa.
Š Rearm: The Rearm parameter is useful for sensors whose values can vary, such as the temperature and humidity
sensors.
It is used to prevent the sensor from rapidly changing between two states. For example if the Warning High threshold
for the temperature sensor is set to 80 degrees and the sensor were to vary between 79 and 80 you could be faced
with a very large number of emails, traps, and events logged. The Rearm parameter prevents this by forcing the
temperature to drop by the Rearm value before changing the state back to normal. In this example, if Rearm is set to
2, then the sensor would have to drop from 80 down to 77 before the status would change from Warning High back
to normal.
