Sometimes you need event rules to turn to false before they can trigger a new notification. In this case, one-shot events come in handy.
The one-shot event rule
1. Edit/create an event rule by accessing Admin > Event Rules menu in your application.
2. In Step 2. Who this rule applies to select only the vehicle(s) / tag(s) that will make use of this rule.
Note: this step is important to avoid performance issues on your server.
3. In Step 4. Expressions, add the exact same expression that triggers the event in Show advanced options
Example 1: using SOS as a variable to track updates of the SOS state.
Example 2: using the Temperature (Analog) signal to capture every temperature variation.
4. Save your event rule.
