Ingest From Any Broker
Subscribe with topic filters and wildcards, then map each topic and JSON path to a tag with a unit.
Protocol Support
MQTT Integration
Subscribe to any broker, publish normalized data back out, and keep topics, QoS and retained state under control.
- Standard
- OASIS MQTT 3.1.1 (ISO/IEC 20922) and MQTT 5
- Medium
- TCP and TLS (port 8883), WebSocket
- Topology
- Publish and subscribe through a broker
- Data Model
- Topic strings with free-form payloads, optionally Sparkplug B
What MQTT Is
MQTT is a lightweight publish and subscribe protocol. Devices send messages to named topics on a broker, and anything subscribed to a topic receives them. MQTT defines the transport, not the payload, so two vendors can both speak MQTT and still send incompatible data. IoTServa treats a broker as both a source and a destination.
Native address
Topic factory/line2/oven/temp
JSON payload {"t":182.4}
QoS 1, retained
Broker over TLS
Normalized tag
site.factory.line-2.oven-temp
182.4°C
How IoTServa Connects MQTT
Publish Normalized Data
Send clean, consistently named values back out to your own broker or a cloud broker, with the QoS you choose.
TLS and Credentials
Connect over TLS with client certificates or credentials, and keep secrets out of project files.
Sparkplug B Aware
Read Sparkplug B birth and data messages so metrics arrive with their types and units.
Typical Jobs
- Collecting data from third-party gateways and sensors
- Feeding a cloud platform or data lake
- Bridging two sites through one broker
- Giving other teams a clean topic structure
Plan for These
Choose QoS deliberately. QoS 0 can drop messages, QoS 2 costs more than most telemetry needs.
Retained messages make a dashboard show stale data as if it were live unless you track message age.
Agree one topic naming scheme per site before devices multiply.
MQTT Questions
Does IoTServa include an MQTT broker?
It connects to the broker you already run, or to one you choose. A broker can also be part of an on-premise deployment.
Can IoTServa publish data out as MQTT?
Yes. Every normalized tag can be published to a broker with a topic pattern you define.
