Take action only on initial trigger: Select this option if you want to send the command after switching from the state of not meeting the condition to meeting the condition. By default, this option is selected. For example, suppose you have created an action to send the command when the temperature recorded by a device exceeds 40 degrees Celsius. Suppose the temperature recorded by the device is as follows: 35, 38, 41, 45, 39, 42. In this scenario, the command is sent when the temperature is 41 and 42.
Take action on every trigger: Select this option if you want to send the command every time the event is triggered. For example, suppose you have created an action to send a command when the temperature recorded by a device exceeds 40 degrees Celsius. Suppose the temperature recorded by the device is as follows: 35, 38, 41, 45, 39, 42. In this scenario, the command is sent when the temperature is 41, 45, and 42.
Select Save or Save and Exit.
