Connect to MQTT
Bridge any Industrial Protocol to MQTT with the UMS (Unified Message Structure). Transform OPC UA, BACnet, and Modbus data into standardized MQTT messages effortlessly.
Why C2MQTT?
Unify your industrial data communication with a single, standardized approach
Unified Message Structure
Standardize data from any protocol into consistent MQTT messages for easy integration.
OPC UA to MQTT
Transform OPC UA data, subscriptions, and alarms directly into MQTT topics.
BACnet to MQTT
Bridge building automation data seamlessly to your MQTT broker.
Modbus to MQTT
Convert legacy Modbus registers to modern MQTT messages instantly.

Method 1: MQTT-Driven Requests
Send items you want to use for a service via MQTT on a topic. These items receive their parameters and correct UMS in a P4NR OPC UA Inject Node, then flow into the service. Work with the results - extract or transform data and publish to another topic. Node‑RED makes this effortless!
Method 2: Custom MQTT Interface
Create your own MQTT interface by sending only the results to MQTT. Node‑RED's MQTT Nodes combined with P4NR OPC UA Nodes make it incredibly simple to dynamically monitor, extract, and transform data onto dynamic MQTT topics!
