UMG 96-EL now with MQTT
Janitza is expanding the UMG 96-EL energy analyzer with the MQTT protocol. The industry standard enables more efficient data transfer for industrial IoT applications.
In September 2025, Janitza is expanding the UMG 96-EL to include the MQTT protocol. It is available with the firmware update Rel. 1.1.0. MQTT stands for Message Queuing Telemetry Transport and refers to an M2M communication protocol. It is optimized for use in IoT environments and is specified in ISO/IEC 20922.
MQTT in industrial use – advantages at a glance
Scalable: MQTT is used in large, distributed systems and supports a large number of connected clients simultaneously.
Reliable: Thanks to the various Quality of Service (QoS) levels, the broker transmits messages even in the event of temporary connection interruptions or network problems.
Efficient: MQTT has little overhead and works efficiently with limited resources such as bandwidth and storage space. It requires only a small amount of bandwidth during transmission and is ideal for high-latency networks. This makes MQTT ideal for use in resource-constrained IoT devices (e.g., small sensors or microcontrollers).
Easy to integrate: MQTT can be seamlessly integrated into existing control and SCADA systems as well as IoT platforms.
Principle of operation
With the MQTT protocol, any number of senders and receivers (clients) such as the UMG 96-EL can be connected to a broker (server). This broker acts as a control center and receives the information from the senders as raw data. The broker distributes the information to each recipient who has subscribed to this information. This means that each recipient only receives the information they really need. The senders and receivers themselves are not connected to each other. Each client can be both sender and receiver at the same time.
The data is sent in data packets, so-called payloads. At least one payload is defined for each sender. There are predefined payloads for the UMG 96-EL to make it easy to get started, but each user can also create their own payloads.
The UMG 96-EL also supports TSL encryption and certificate handling, ensuring secure data transmission.
