Introduction
This rule represents a pattern that can be used to enable or disable entities or to control actions in response to track behaviour. Note that the timer input is required to ensure the actions do not flip-flop when different tracks are processed by rule. For example a track inside the area will meet the requirements of the area check and therefore the actions will be triggered, however the next track checked could be outside the area in which case the area check will fail and the actions will be reversed. To avoid the actions being continuously triggered and then reversed the timer is used to keep the area rule output true for the specified time period. This means as long as a track is in the area the timer period will be reset and the rule will remain broken until the track has left the area and the timer has expired.
This example demonstrates the ability to enable or disable another rule based on whether a track is detected in the specified area.
