Sm@rtGear IE

Smarter Power Distribution. Zero Disruption. Total Visibility. Sm@rtGear IE is an intelligent power distribution solution designed for the demands of industrial environments with real-time monitoring, predictive diagnostics, and remote-control capabilities.

Sm@rtGear® MQTT API

Comprehensive MQTT API documentation for Sm@rtGear® Industrial Edge applications and services.

Overview

The Sm@rtGear® communication ecosystem provides secure MQTT messaging and complementary APIs for integrating with all Sm@rtGear® Industrial Edge applications. MQTT enables real-time data streaming, device communication, and seamless integration with existing industrial systems.

Data Model Reference

The Sm@rtGear IE Data Model organizes all data points by MQTT topic structure. Each category below links to detailed documentation:

For topic structure and usage, see the Data Model Overview.

MQTT Broker Services

Real-Time Data Streaming

MQTT topics for live data feeds from Sm@rtGear® Industrial Edge devices and applications.

  • Power Quality Data Streams - Real-time power quality measurements and events
  • Thermal Monitoring Streams - Continuous temperature data from monitoring points
  • Equipment Status Streams - Live equipment health and operational status
  • Alarm & Event Streams - Immediate notifications of critical events

Device Communication

MQTT-based device-to-device and device-to-cloud communication.

  • Device Configuration - Remote configuration of Sm@rtGear® devices
  • Command & Control - Send control commands to field devices
  • Firmware Updates - Over-the-air firmware update notifications
  • Device Health Monitoring - Continuous device connectivity and health status

Authentication & Security

All Sm@rtGear® MQTT communications use industrial-grade security protocols:

  • TLS/SSL Encryption - All MQTT traffic encrypted with TLS 1.3
  • X.509 Certificates - Device authentication using certificates
  • Username/Password - Additional authentication layer
  • Topic-Level Authorization - Granular access control per MQTT topic
  • Secure Boot - Device integrity verification

MQTT Configuration

Connection Parameters

  • Broker Address: mqtt.smartgear.siemens.com
  • Port: 8883 (TLS encrypted)
  • Protocol: MQTT v5.0 (with fallback to v3.1.1)
  • Keep Alive: 60 seconds
  • Clean Session: False (persistent sessions)

Quality of Service (QoS)

  • QoS 0 - Best effort delivery for non-critical data
  • QoS 1 - At-least-once delivery for important events
  • QoS 2 - Exactly-once delivery for critical control commands

Message Retention

  • Critical Alarms: Retained for immediate delivery to new subscribers
  • Status Updates: Retained for current state information
  • Historical Data: Not retained (use time-series database for history)
