==Introduction==
+
__TOC__
This article contains instructions on how to send M-Bus data to the server using various protocols.
+
==Summary==
 +
In this guide, the MQTT Serial Gateway function will be configured using third-party MQTT Broker services (in this example, ''Flespi.io'').
   −
==Configuration overview and prerequisites==
+
==Configuration overview & prerequisites==
 +
*Two devices with serials ports - one acts as Modbus RTU Master, another as Modbus RTU Slave;
 +
*Flespi.io account to act as an MQTT Broker/Publisher/Subscriber (for first configuration example);
   −
Before we begin, let's take a look at the configuration that we are attempting to achieve and the prerequisites that make it possible.
+
[[File:MQTT Serial gateway topology v2.png|border|center|class=tlt-border|847x279px]]
   −
'''Prerequisites''':
+
RUT2 will act as a Modbus RTU slave and RUT1 as a Modbus RTU Master. On RUT1, MQTT Serial Gateway will be configured to transfer Modbus data over MQTT. Flespi.io platform will serve as an MQTT Broker
* 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.
+
==RUT2 configuration==
[[File:TRB143 advanced.gif|border|center|class=tlt-border|1004x1004px]]
+
===Configuring Modbus RTU Slave===
 +
----
 +
Go to Services → Modbus → Modbus RTU Slave and create a new instance.
 +
# Enter the '''desired instance name''';
 +
# Select the '''desired serial interface'''.
   −
==Node-RED installation and setup==

We are going to set up Node-RED in a 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 the Node.js version using this command:
+
==RUT1 configuration==
<pre>
+
===Configuring MQTT Gateway===
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:
  −
[[File:Server is running node red terminal.png|border|600px|class=tlt-border]]
   
----
 
----
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:
+
Go to '''Services → Modbus → MQTT Gateway''' and there:
[[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 the Manage Palette section and install these nodes:
+
# '''Enable''' the '''instance''';
*node-red-contrib-aedes
+
# '''Enter Host''' (copied from flespi connection settings without 'wss://' and port);
*node-red-contrib-mqtt-broker
+
# '''Enter Username''' (Copied from flespi Connection settings generated '''token''');
 +
# '''Enter Password'''.

===M-Bus Data to Server via MQTT===
+
===Configuring Serial Gateway===
----
  −
This section contains information on how to send M-Bus data to the server on Node-RED using the MQTT protocol.
  −
====Data to Server configuration====
   
----
 
----
The '''[[TRB143_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. This section will walk you through configuring the Data to Server to send M-Bus data to the Node-RED server. To configure Data to Server, '''access the router's WebUI''' and navigate to '''Services''', then '''Data to Server''':
+
Under the MQTT Gateway configuration, create the Serial Gateway:
 
+
# Enter the '''desired device ID''';
# '''Enable''' instance;
+
# Select the '''desired serial interface'''.
# '''Name:''' Enter '''desired''' '''instance name''';
  −
# '''Data source:''' M-bus;
  −
# '''Protocol:''' MQTT;
  −
# '''JSON format:''' Enter what '''data''' you would like '''to send''';
  −
# '''URL/Host/Connection string:''' Enter '''address of server''';
  −
# '''Port:''' Enter '''server port''';
  −
# '''Topic''': Enter '''desired''' '''topic name'''
     −

   −
====M-Bus configuration====
+
===Configuring Flespi.io MQTT Broker===
 
----
 
----
The '''[[TRB143_M-Bus|M-Bus Settings]]''' section is used to configure the general service functionality. To set up a new M-Bus instance, go to '''Services → M-Bus:'''
+
'''Log in''' or '''create an account''' on '''https://flespi.io''';
 
  −
# '''Enable''' M-Bus;
  −
# '''ID''': Enter desired '''instance name''';
  −
# '''Add''';
  −
 
  −
[[File:M bus configuration correct.png|border|class=tlt-border|904x904px]]
  −
 
  −
After this, you should be redirected to the configuration page for the M-Bus instance:
  −
 
  −
[[File:M bus instance creation.png|border|class=tlt-border|904x904px]]
     −
# '''Enable''' instance;
+
#Navigate to '''MQTT Board''' on the '''left side''' menu;                                        
# '''Name''': Enter your '''desired name''';
+
#On the right-hand panel, top right corner, next to the name of the MQTT board, '''press the cogwheel-looking icon''' to open ''Connection Settings'';
#'''Period''': Enter '''desired period''';
+
#In the opened window, press '''"Get flespi token"''' to generate a username;
At the bottom of the M-Bus instance, you should see the Request Configuration section. It is used to configure requests from M-Bus devices.  
+
#Enter the '''Client name''';
 +
#Copy the Host address;
 +
#Copy '''Username''';
 +
#Create a '''password'''.
   −
[[File:HEX data type.png|border|class=tlt-border|904x904px]]
+
Once done, save all the changes.
 +
[[File:Flespi board.png|border|center|class=tlt-border|1102x729px]]
   −
# '''Enable''' request configuration;
+
===Message format for MQTT publisher===
# '''Slave address:''' Enter '''desired slave address''';
  −
# '''Data type:''' Select desired data type (this time we will be using '''HEX''');
  −
# '''Save & apply''' changes.
  −
====Node-RED configuration====
  −
----
  −
Below you can see the Node-Red block diagram that is used to receive data and its configuration:
  −
* '''aedes broker block''' - Broker;
  −
* '''MQTT in block''' - mbus;
  −
* '''Debug''' - debug 2;
  −
[[File:Node-rs-topology.png|border|center|class=tlt-border|654x654px]]
