I'm trying to set up a low flow notification for a tank. If the average flow is less than 50 gpm (white noise) 20 min after 7:15 AM, PI should send an email to me, and I will remind the operator to start the tank pump. I don't need to check this on weekends. I formulated that as is shown in the attachment. However, I'm not sure what the closing criteria should be as I want that event to be kinda closed after a 1-time notification has been sent to me.
