JUG 25

The easiest way to bring Modbus measurement data to the cloud
With JUG 25, you can quickly and easily integrate existing Modbus-based energy measuring devices into modern IoT and cloud architectures.

Maximum flexibility for heterogeneous system environments
The gateway supports both Modbus RTU and Modbus TCP and transfers data from Modbus to MQTT.

Retrofit instead of replacement – keep using your existing infrastructure
Already installed measuring devices can be integrated into MQTT-based systems, allowing users to digitize existing installations without investing in new hardware.

Future-proof architecture for IoT and smart building projects
The Universal Gateway JUG 25 supports all MQTT versions (3.1.0, 3.1.1, 5.0) and is ideally suited for modern IoT architectures and cloud-based data platforms.

Seamless integration into modern IT and building management systems
JUG 25 transmits measurement data from field devices and energy monitoring systems (Modbus) directly to IT systems, data lakes, or cloud platforms via MQTT.

Data buffering during connection interruptions
In the event of short-term connection losses between the gateway and the MQTT broker, measurement data is retained thanks to a ring buffer storage.

Ideal complement for Janitza energy measuring devices
The gateway is perfectly aligned with the Janitza device family, enabling particularly fast configuration and integration.

Modbus converter
Can be operated as a Modbus TCP-to-RTU converter, seamlessly connecting modern TCP systems with existing RTU devices.
