Question

Hi I am trying to send Modbus RTU data to Azure.

I was able to configure and see modbus data via modbus serial master.

If I use the cloud solutions section then azure iot hub and select GSM values they push through to Azure:

But when I disable the above and go to the "data to server" section and try and enable Modbus data to azure Mqtt I am getting nothing relecting in Azure.

Does the TRB145 allow Modbus serial data to the azure server and is the above the right way to do it?

Hello,

I would like to review your configuration. Please attach a troubleshoot file to your question. First, replicate the issue, then access router's WebUI, go to System -> Administration -> Troubleshoot section and download troubleshoot file from there. The logs in the file might provide more insight into the issue.

Best regards,

Hello,

I managed to get it right, what was wrong was the format of the JASON. This was silly as I used the tutorial's example which had a typo with an extra } and fixing that the data is streaming through. Is it possible to write back a modbus value?
