For the Automation scenario of: “When the temperature is higher than 40, send Email Notification" with a limit period of 1 hour”, if the temperature rises and exceeds 40 at 9:30 am, then no additional notifications will be sent until 1 hour later at 10:30 am. At 10:30 am, the limit period resets, permitting another notification to be sent at 11:30 am if the temperature continues to exceed 40.
