State field value
Overview
In telematics, a state field represents the current status of a specific vehicle component or system, such as whether a door is open or closed, the handbrake is engaged, or an airbag is deployed. It provides real-time data on these elements, enabling monitoring and alerts based on changes in their state.
The "State field value" rule is designed to utilize this data by monitoring specific state fields and triggering alerts when predefined conditions are met. This rule is essential for keeping users informed about critical events, such as when a door is unexpectedly opened, the handbrake is released, or an advanced driver assistance system (ADAS) is activated.
For example:
If a vehicle’s airbag deploys, the state field for the airbag will change, prompting the rule to send an alert.
If a diagnostic trouble code (DTC) is detected, the system can instantly notify the user, enabling prompt maintenance action.
By using this rule, organizations can enhance safety, improve security, and streamline maintenance processes through real-time notifications and detailed event reports.
Rule settings
State field
Specify the field to be monitored (e.g., Trunk). Set the expected value (e.g., Opened) to trigger a notification when the condition is met. The "Allow repeat" option controls how frequently the same event will trigger notifications.
Expected value
Choose the value that the state field must match to trigger a notification (e.g., Opened/Closed). For special events, such as a hardware key or event code, enter the specific value provided by the device manufacturer.
Allow repeat
Unselected: The event triggers only when the state changes to the expected value after a different value has been received.
Selected: The event triggers each time the expected value is received, but not more frequently than the "Repeat delay" allows.
Repeat delay
Set the reset timer in seconds to control how often the event can trigger notifications. For example, setting it to 1800 seconds limits notifications to once every 30 minutes.
For common settings, please refer to Rules and notifications.
System operation details
Virtual sensors availabilty. Users can also select virtual sensors as data sources in the state field rule. This allows for customized notifications and reports based on virtual sensor data, enabling more tailored monitoring and management of critical events.
Reset timer: The "State Field Value" alert has a default reset timer of 5 minutes, meaning the event will not trigger more frequently than once every 5 minutes.
Single device support: Each rule applies to one device only, as different state fields cannot be cross-referenced across multiple trackers.
GPS-independent processing: The platform processes and displays state field events even if GPS data is missing, ensuring that important events are not overlooked due to location issues.
