Need Help Configuring MQTT for M-Bus Data on TRB143

[Mattes_ETA]

I am working on configuring my TRB143 to send M-Bus meter data via MQTT, but I am encountering issues with the data not being published correctly. I’ve set up each meter with its instance in the “Data to Server” service, but something seems to be missing. Here are the details of my current setup:

1. General Setup:

• Server Type: MQTT
• Data Type: M-Bus data
• Format Type: Custom
• Collection Interval: 15 seconds
• MQTT Server Address: 192.168.2.1
• Port: 1883
• Topic: trb143/json
• QoS: 0

2. Data Configuration:

• Name: data
• Format String: %data%
• Delimiter: Comma (,)
• Empty Value: N/A
• Segment Count: 5

Despite these settings, I am unable to see the values when I connect via MQTT Explorer. I suspect there might be an issue with how I’ve configured the data format or MQTT topics.

Could anyone provide some insights or suggestions on what might be going wrong? If you’ve set up something similar on your TRB143, I would greatly appreciate any advice or configuration examples.

Hi Mattes_ETA,

Firstly, did you try to use the test feature of TRB143 to confirm that the gateway can pull out the M-bus data from your meter? More information in this link.

Also, input the necessary MQTT server address/hostname. I think you put the gateway’s IP in that instance.

Let me know if this helps.
