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

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

- **Scenario 1**: Control a relay when fuel level drops below 10%. - **Scenario 2**: Trigger a buzzer if RPM exceeds 3000 while ignition is ON. - **Scenario 3**: Activate an alarm when GSM signal strength drops below 20%.
