Custom Scenarios

Introduction to Custom Scenarios functionality

To meet the diverse and evolving needs of our clients, we have developed the Custom Scenarios feature. This solution allows users to define specific conditions using customizable parameters to generate events or control a device’s digital outputs. By connecting the device to peripherals like alarms, buzzers, or relays, this functionality can notify drivers or perform targeted actions seamlessly.

The feature enables the device to operate autonomously based on predefined conditions, eliminating the need for constant monitoring of device status or complex backend integrations. With Custom Scenarios, any data the device can send becomes a potential input for controlling digital outputs, providing flexibility and efficiency.

Custom Scenarios description

Figure 1. “Custom Scenarios” functionality logic

The Custom Scenarios functionality enables configuration of up to three independent scenarios, each with up to three unique triggers. Triggers are defined using data as source from various I/O elements, such as: Fuel Level, Engine RPM, Seatbelt Status, DTC Faults, Movement Status, Ignition State, GSM Signal Level, 1-Wire or Bluetooth sensor temperature and etc. Each source is configured with specific logic operands, threshold values, and an activation delay timer, which specifies how long a value must remain within the defined range before the trigger is activated.

When all triggers of a scenario are 'true', the scenario becomes active. This can generate a record and/or control the Digital Output by toggling it on or off based on the active conditions. Additionally, if configured for continuous operation, the DOUT remains active as long as the conditions are met.

Key features include:

• Support for dynamic trigger logic based on selected operands and conditions.
• Autonomous device operation, even in low-power or deep-sleep modes, provided compatible I/O sources are used.
• Adjustable ON/OFF durations or permanent output control, enabling versatile device behaviors such as blinking or continuous activation.
• Custom Scenarios operate independently from the I/O menu, with priority management ensuring that higher-priority scenarios take precedence in controlling the DOUT when multiple scenarios are configured.

Output control and eventual record logic

Records are generated when all enabled trigger conditions are met, and the scenario activates, also controlling the configured DOUT state. If the priority is set to "None", no record will be created; however, the scenario will still control the DOUTx if it is configured your configuration. For more details on priority, refer to this page

Eventual record AVL ID list

Custom Scenario	AVL ID	DOUTx State	Record Value
Custom Scenario 1	1163	OFF -> ON	1
		ON -> OFF	0
Custom Scenario 2	1164	OFF -> ON	1
		ON -> OFF	0
Custom Scenario 3	1165	OFF -> ON	1
		ON -> OFF	0

Output control priority management

Custom scenarios can be configured to use the same or different digital outputs. When multiple scenarios are assigned to the same digital output, the scenario with the highest priority takes control when active. Custom Scenario 1 has the highest priority, while Custom Scenario 3 has the lowest. The priorities of all device scenarios:

Priority	Scenario
#1	SECO
#2	Towing
#3	Immobilizer
#4	Private Mode
#5	DOUT Control Via Ignition
#6	Call
#7	Authorized Read Notification
#8	Green Driving
#9	Jamming
#10	Overspeeding
#11	Idling
#12	DOUT Control via SMS
#13	Custom Scenario 1
#14	Custom Scenario 2
#15	Custom Scenario 3
#16	GNSS Jamming
#17	Diagnostic Tool Maintenance

Overide digital output using remote commands

“setdigout“ can override Digital Output status if controlled by Custom Scenarios and if required “cleardigoutprio“ can be used for Custom Scenarios be capable of controlling the DOUT again.

Logic using inverted digital output

If inverted digital output mode is enabled and the same digital output is configured for a custom scenario, the digital output operates in inverted mode when the custom scenario is inactive. When the custom scenario becomes active and has higher priority, it overrides other controls, and the digital output switches to normal mode. Once the custom scenario is inactive, the digital output reverts to inverted mode.

Source value calculation

Source value is the calculated parameter value ID of the selected source. The possible sources depend on the hardware. The sources are based on the I/Os, their parameter value IDs (which are needed when setting sources via commands) can be calculated:

Parameter value ID = (I/O Element AVL ID - I/O Group First Element AVL ID) * 10 + I/O Group AVL ID

I/O Group Name	I/O Group AVL ID	I/O Group First Element AVL ID
Base	50000	0
LVCAN	45100	478
OBD	40100	398

For example: IButton I/O AVL ID is 39, so parameter value ID will be (39 - 0) * 10 + 50000 = 50390. It can be set using "setparam" command to remotely change configuration of Custom Scenarios source to be IButton remotely. To check element AVL ID list refer to this page.

Examples of use cases and their configuration

Monitoring vehicle refrigerated compartment temperature and informing driver

Figure 3. “Custom Scenarios” functionality logic

Configure a Custom Scenario to monitor and notify on abnormal temperature readings in a refrigerated vehicle compartment:

• Select "Low priority" for device to create and eventual records as notification
• Select "Digital Output", which is connected to external peripheral such as LED that will notify driver
• Define "Digital Output" control period
• Choose used sensor data as source, in this case "EYE Temperature #1"
• Choose operand "On exit" to define that trigger is active when reading value exits the configured range
• Define temperature range 1°C to 4°C (e.g., Low Level = 100, High Level = 400), to determine correct Low/High level values consider what type of preset is used for Bluetooth sensor and this element multiplier
• Configure activation delay timer (e.g., 60 seconds) to prevent triggering on small fluctuations or simply to define limits on how temperature can be out of range

Optionally enable second condition trigger as "Ignition" to notify driver only when vehicle is used:

• This can be done by entering "Trigger #2" menu by pressing on ▼ and choose "Ignore" parameter option "No"
• "Logic" "AND" option should be further selected to make sure that Custom Scenario respects both conditions
• Define that second trigger source is "Ignition"
• Operand "Is" and "Low level / High Level" values selected as "1" will allow to define that second Trigger is "true" once Ignition element value is "1"

This configuration ensures that Digital Output is controlled by turning on and off for 5 seconds only when the vehicle is active, and the temperature exceeds the specified range for 60 seconds.

Benefits:

• Proactive Monitoring: Early detection of temperature anomalies minimizes product spoilage risks
• Cost Efficiency: Reduces losses due to temperature-sensitive cargo damage
• Regulatory Compliance: Ensures adherence to industry standards for refrigerated transport
• Enhanced Decision-Making: Provides actionable insights for operational improvements

Driver identification with notification steps

Figure 4. “Custom Scenarios” functionality logic

Set up a multi-stage notification system to ensure driver authorization:

First Stage:

• For Custom Scenario 3, select "Disable" to exlcude device creating eventual records as notification for the first stage
• Select "Digital Output", which is connected to external peripheral such as LED that will notify driver
• Configure the "Digital Output" control period with extended on/off intervals to regulate the LED, ensuring steady signaling during the initial stage of the notification
• Choose used identification data as source, in this case "iButton"
• Operand "Is" and "Low level / High Level" values selected as "0" will allow to define that first Trigger is "true" if "iButton" element value is "0"
• Enable second condition trigger. This can be done by entering "Trigger #2" menu by pressing on ▼ and choose "Ignore" parameter option "No"
• "Logic" "AND" option should be further selected to make sure that Custom Scenario respects both conditions
• Define that second trigger source is "Ignition"
• Operand "On entrance" and "Low level / High Level" values selected as "1" will allow to define that second Trigger is "true" once Ignition element value switches from "0" to "1" at moment of key being turned to ACC position
• Configure activation delay timer (e.g., 60 seconds) to define after what time period at initial stage of identifaction reminder will start

Second Stage:

• For Custom Scenario 2 same settings can be applied and only few additional steps needed
• Adjust "Digital Output" control period with shorter on/off intervals to regulate the LED, ensuring more frequent signaling during the second stage of the notification
• Adjust activation delay timer (e.g., 120 seconds) to define after what time period at second stage of notification reminder will start

Third Stage:

• For Custom Scenario 3 same settings can be applied and only few additional steps needed
• Activation delay switched to 180 seconds for maximum allowable time before third notifaction stage starts
• Conditions remain the same, but a different Digital Output can be used, connected to periphela such as buzzer, which acts as an alarm
• In order to active Digital Output permenently until identification using iButton is made configure "Permanent Output Control" as enabled.

This configuration ensures a gradual escalation of notifications and triggers an alarm if the driver fails to authorize within 3 minutes, since higher priority Custom Scenario will take over Digital Output control after conditions were met for specific time.

Benefits:

• Ensures that only authorized drivers can operate the vehicle: reducing the risk of unauthorized usage or theft.
• Gradual escalation of alerts provides a clear warning system: deterring unauthorized access without immediate disruption.
