Introduction

This article contains instructions on how to send M-Bus data to the server using various protocols.

Configuration overview and prerequisites

Before we begin, let's take a look at the configuration that we are attempting to achieve and the prerequisites that make it possible.

Prerequisites:

• TRB143;
• M-Bus device;
• Server;
• An end device (PC, Laptop, Tablet, Smartphone) for configuration;

If you're having trouble finding any page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode," which is located at the top-right corner of the WebUI.

Configuration

Data to server

Data to Server feature provides you with the possibility to set up data senders that collect data from various sources and periodically send it to remote servers.

Via MQTT

This sections contains information on how to send M-Bus data to the server on Node-RED using MQTT protocol.
