Rule Engine Overview

The Rule Engine is a powerful, flexible system designed to process data in real-time and trigger actions based on predefined conditions. It serves as the brain of your IoT ecosystem, enabling automated decision-making and responses to various events and data inputs.

Key Features​

1. Real-time Data Processing​

  • Instant Trigger Activation: Rules are evaluated in real-time as data flows into the system.
  • Low Latency: Designed for quick response times, crucial for time-sensitive applications.
  • Scalability: Capable of handling high volumes of data from numerous devices simultaneously.

2. Versatile Trigger Types​

  • MQTT: Responds to device data sent via MQTT protocol.
  • HTTP Webhooks: Triggers based on incoming HTTP requests.
  • GeoLocation: Dynamically define your GeoFence and detect events like on-exit, on-enter, outside and inside.
  • Device State Changes: Activates on changes in device shadow.

3. Conditional Logic​

  • Complex Conditions: Supports intricate boolean logic and comparisons.
  • Data Point Referencing: Ability to reference specific data points from devices or contexts.
  • Historical Data Analysis: Can consider past data for trend-based decisions.

4. Action Types​

  • HTTP Requests: Interact with external APIs and services.
  • Device Shadow Updates: Modify device state or configuration.
  • User Metadata Operations: Update or retrieve user-related information.
  • Data Insertion/Update: Manipulate data in user contexts or other storage.
  • FCM Notifications: Send push notifications to mobile devices.
  • Device Metadata Operations: Update or retrieve device-related information.

5. Third-Party Service Integration​

  • API Connections: Seamlessly connect with external services via HTTP actions.
  • Webhook Support: Both as triggers and actions for bi-directional integration.
  • Authentication Handling: Supports various auth methods including Basic Auth and API keys.

6. FCM (Firebase Cloud Messaging) Notifications​

  • Mobile Push Notifications: Send alerts directly to user devices.
  • Customizable Payloads: Tailor notification content based on rule data.
  • User Targeting: Send notifications to specific users or groups.

7. Context Awareness​

  • Fetched Contexts: Ability to pull in additional data from various sources:
    • Device shadows
    • Device locations
    • User metadata
    • User contexts
    • Fleet data

8. Advanced Features​

  • Chaining: Create sequences of actions for complex workflows.
  • Looping: Iterate over datasets or perform repeated actions.
  • Error Handling: Configure backoff strategies and retries for robust execution.
  • Templating: Use dynamic values in action configurations.

Use Cases​

  1. Predictive Maintenance
    • Monitor device health metrics
    • Trigger maintenance alerts before failures occur
  2. Geofencing
    • Track device locations
    • Trigger actions when devices enter or exit defined areas
