The Internet of Things (IoT) is the communication and networking of real objects via the Internet. In addition to devices such as computers, smartphones and tablets, more and more objects from the “offline world” are joining them, such as cars, televisions, wristwatches, heaters, weather stations and household appliances.
The KaTe MQTT Adapter for SAP PO connects your SAP system landscape, i.e. SAP Process Integration & SAP Process Orchestration with the Internet of Things.
The KaTe MQTT Adapter is also available for SAP CPI (Cloud Platform Integration) or SAP HCI.
Message Queueing Telemetry Transport (MQTT) is an open standard for lightweight message transfer between devices, sensors, and applications with high latencies and deployment in low-bandwidth networks.
SAP PI – Process Integration
SAP Process Integration is SAP’s Enterprise Service Bus (ESB) solution for A2A and B2B scenarios, offering a wide range of adapters and integration tools (e.g. transformation, orchestration, routing, reliable messaging and monitoring). SAP Process Orchestration 7.31 additionally provides numerous BPM functions and a rules engine.
MQTT – Message Queue Telemetry Transport
Message Queueing Telemetry Transport (MQTT) is an open standard for lightweight message transfer between devices, sensors, and applications with high latencies and deployment in low-bandwidth networks.
The MQTT protocol has been standardized by Oasis as the “Internet of Things” protocol since 2013. In addition to its traditional use in sensor networks, connected manufacturing and home automation, MQTT is also increasingly used in mobile scenarios (e.g. in Facebook Messenger).

KaTe MQTT Adapter Features
The history of MQTT
The MQTT protocol has gained a lot of popularity in recent years. MQTT was programmed in 1999 by Andy Stanford-Clark (IBM) and Arlen Nipper (Cirrus Link) for monitoring oil and gas pipelines. Transmitting data via satellite has always been very costly and therefore a smart solution was sought. The Message Queue Telemetry Transport, or MQTT, protocol which was developed in this manner fulfilled the required characteristics. Following this project, MQTT was used and further developed as a proprietary protocol at IBM in a variety of projects. In 2010, the MQTT specification was released to the public and since then a large infrastructure has developed around it.
The KaTe MQTT Adapter enables secure and seamless integration of MQTT-based IoT systems with SAP environments, including SAP Integration Suite (CPI) and SAP Process Orchestration (PO). It allows real-time event processing from devices, sensors, and machines into SAP business processes.
The adapter connects directly to MQTT brokers (e.g. Mosquitto, HiveMQ) and automatically transforms MQTT messages into SAP-compatible formats like XML, JSON, or IDoc. Key features include:
Full Publish & Subscribe support
Filtering by topic, QoS level, and payload content
Real-time data processing for high-throughput IoT scenarios
Yes. The KaTe MQTT Adapter is fully compatible with the SAP Business Technology Platform (BTP). It works in both SAP Cloud Integration (CPI) and on-premise SAP PO environments, making it ideal for hybrid or transitional system landscapes.
The adapter supports all modern MQTT security standards, including:
TLS/SSL encryption
Client certificate authentication
Username/password-based login
This ensures secure data exchange even in production-grade industrial IoT environments.
Common scenarios include:
Industrial IoT integration with SAP ERP or S/4HANA
Machine and sensor data collection and processing
Event-driven workflows in maintenance, logistics, or monitoring
The adapter ensures scalable, high-performance, and fault-tolerant data flows between IoT devices and SAP systems.
