24.2.4 Create a new alarm trigger with sensor value
Triggers controlled by an analogue sensor, must be configure with threshold
value. E.g. if you want to create a trigger that alarms if the temperature gets
above a given temperature, you must set the rising threshold value to the alarm
temperature. The falling thresholds may be set to the same value, but by using
different thresholds (rising higher than falling) one can avoid receiving multiple
events when the temperature fluctuates around the alarm threshold.
