Flow object structure

1. Basic Properties:

   • id: Unique identifier for the flow

   • title: Name of the flow for display purposes

   • enabled: Toggle to activate or deactivate the flow

2. Nodes: The building blocks of the flow, each with a specific purpose:

   • Data Source Nodes (type: "data_source"): Define the input sources for data

   • Initiate Attributes Nodes (type: "initiate_attributes"): Process and transform data

   • Output Endpoint Nodes (type: "output_endpoint"): Define where processed data is sent

3. Edges: Connect nodes together to define the flow of data

Node Types in Detail

Data Source Node

• Acts as the entry point for data from devices

• Contains a list of source device IDs to monitor

• Example use: Collect data from vehicle trackers, temperature sensors, etc.

Initiate Attributes Node

• Processes data by creating or modifying attributes

• Uses expressions to transform raw data into meaningful metrics

• Can reference other attributes in calculations

• Example use: Convert analog signals to meaningful metrics (fuel level, temperature)

Output Endpoint Node

• Defines the destination for processed data

• Two main types:

  • Navixy Output: Sends data to the Navixy platform

  • MQTT Client Output: Sends data to external MQTT brokers

Customization for Manufacturers

This template can be customized for different manufacturers by:

1. Adjusting attribute calculations to match the specific sensor outputs and units of a particular manufacturer's devices

2. Adding manufacturer-specific attributes that may be unique to certain vehicles or devices

3. Configuring appropriate endpoints based on the manufacturer's preferred data handling systems

For example, if adapting for a specific truck manufacturer, you might:

• Adjust fuel calculations based on their specific tank sizes and sensor characteristics

• Add attributes for manufacturer-specific features (e.g., DEF levels, regeneration status)

• Configure outputs to integrate with their fleet management systems
