I just discovered this "IFTTT Help" topic, so I'm cross-posting my questions here.
I will add this specific example, too: When I first enabled the Rachio service in IFTTT, there was a pre-made applet (by Rachio) called Track Watering in Google Spreadsheet. One of the elements in that applet is DurationInMinutes. I can edit the applet, and I can remove or re-add that element to it.
But when I create my own applets using the Rachio service and the Event Registered event, that element (DurationInMinutes) is not available. If I click Add Ingredient, there are only two elements available (CreatedAt and DeviceName). Why isn't DurationInMinutes available?
