====Edge Modes==== There are three distinct modes for a trigger - it can be called on the //rising edge//, the //falling edge// or //both edges//. In this case 'edge' means when the trigger condition (for example, that the temperature is higher than 70 degrees) changes. A **rising** edge is a movement from a low value (False/0) to a true value (True/1). A **falling** edge is a movement from a high value (True/1) to a false value (False/0). If responding to **both** edges, the function will be called both when the value changes, regardless of direction. Note that you can check the [[Condition]] property of the trigger to check if the condition that caused the function to be called was True or False.
