Change Over Time Events For Weight

Impact supports a “change over time” event type for the “weight” measurement type. This page explains this event type and how it triggers associated actions.

The change over time event depends on new readings. When a new reading is submitted, the rule will evaluate the submitted reading against the min or max (depending on gain or loss configuration) over the configured duration to determine if the event will trigger the associated action.

Let’s say that we have an event configured for a weight gain of > 5 lbs in 72 hours:

• For this example imagine I have selected the action fire Every Time and not At most once a day

Open

And we have the below readings:

The following readings will be evaluated in yellow when the new reading (206 lbs) is submitted, as these are within the 72-hour window:

The min value in this dataset for evaluation is: 200 lbs

The submitted reading (206 lbs), would trigger the rule, as the delta/gain is greater than 5 lbs:

Additionally submitted readings will be evaluated against the time duration window. For example, if the user immediately submits another reading minutes later (207 lbs, say), the rule will trigger again, as it continues to be evaluated against the min within that time range (200 lbs).
