| ==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.

| ==Node-RED installation and setup==
| |
|
| |
| We are going to set up Node-RED in Linux virtual machine. For Node-RED to work, you would need to install Node.js version 14.00 or higher, if you already have Node.js installed, verify Node.js version using this command:
| |
| <pre>
| |
| node -v
| |
| </pre>
| |
| If you do not have Node.js installed, run these commands to install it:
| |
| <pre>
| |
| sudo apt install curl
| |
| curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash –
| |
| sudo apt-get install -y nodejs
| |
| </pre>
| |
| Once we have Node.js installed, we can install Node-RED. Use this command to install:
| |
| <pre>
| |
| sudo npm install -g –unsafe-perm node-red
| |
| </pre>
| |
| Use the command ''node-red'' to start a local server. Here is how the terminal should look like if the server starts correctly:
| |

| |
| ----
| |
| Once you have the local server running, use the local IP and port number in your internet browser. In this case, we are using 127.0.0.1:1880:
| |
| [[File:Use server address in web browser.png|border|500px|class=tlt-border]]
| |
|
| |
| For MQTT usage, we are going to need MQTT-specific nodes. Use the side menu to navigate to Manage Palette section and install these nodes:
| |
| *node-red-contrib-aedes
| |
| *node-red-contrib-mqtt-broker
| |
