Parameter in range
Overview
The “Parameter in Range” rule is a powerful tool that helps you monitor critical sensor data in real-time. It automatically alerts you when measurements, like temperature or voltage, fall within or outside specified thresholds. This rule ensures you stay informed about important metrics, allowing you to take quick action when needed.
For example, a logistics company can use the “Parameter in Range” rule to monitor temperature-sensitive cargo. By setting temperature limits (e.g., +2°C to +10°C or 35°F to 50°F), the system sends instant alerts if the cargo temperature goes outside the safe range. This enables timely responses to protect the shipment and maintain compliance.
Rule settings
Sensor
Specify the measurement sensor (physical or virtual) that will serve as the data source for alerts. Only a single sensor can be assigned per rule, meaning each tracker requires a separate rule.
More or Equal
Set the lower boundary of the acceptable range.
Less or Equal
Set the upper boundary of the acceptable range.
Value Threshold
This parameter adds a buffer around the defined boundaries to account for sensor noise or inaccuracies. The threshold helps distinguish between "IN range" and "OUT range" states by creating a tolerance zone around the set values. If no threshold is specified, it defaults to 0.03. This prevents frequent triggering of events due to minor fluctuations in sensor readings.
For common settings, please refer to Rules and notifications.
System operation details
Range transitions:
IN to OUT: The state changes from "IN range" to "OUT range" when the sensor value moves beyond the outer buffer.
OUT to IN: The state changes from "OUT range" to "IN range" when the sensor value moves within the range but outside the inner buffer.
Virtual sensors: When using a virtual sensor as the data source, the range is defined according to the virtual sensor's original value. This is useful for controlling specific state fields or event codes within a specified range.
Reset timer: The "Parameter in Range" alert has a 10-second reset timer, ensuring that alerts are not triggered more frequently than every 10 seconds, which helps prevent redundant notifications.
Single device support: Each rule supports only one device due to the complexities of cross-referencing multiple sensors, trackers, and calibration data.
GPS-independent processing: The platform processes and displays events even if the data packet lacks valid GPS coordinates, ensuring that all relevant events are captured and displayed regardless of geofence settings.
