| + | ==Summary== |
| + | In this guide, the MQTT Serial Gateway function will be configured using third-party MQTT Broker services (in this example, ''Flespi.io''). |
| | | |
− | ==Summary== | + | ==Configuration overview & prerequisites== |
− | <b>Inputs</b> and <b>outputs</b> are used for monitoring and controlling a connected device or receiving signals from that device in order to trigger certain events.
| + | *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); |
| + | |
| + | [[File:MQTT Serial gateway topology v2.png|border|center|class=tlt-border|847x279px]] |
| | | |
− | ==Configuration overview and 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 |
| | | |
− | Before we begin, let's overview the configuration that we are attempting to achieve and the prerequisites that make it possible.
| + | ==RUT2 configuration== |
| + | ===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'''. |
| | | |
− | '''Prerequisites''':
| + | [[File:Modbus RTU Slave.png|border|center|class=tlt-border|855 × 308px]] |
− | * Two RUT955 routers (one of them with an active data connection)
| |
− | * An end device (PC, Laptop, Tablet, Smartphone)
| |
− | * Router's LANs should be in different subnet
| |
| | | |
− | ==Router configuration== | + | ==RUT1 configuration== |
| + | ===Configuring MQTT Gateway=== |
| + | ---- |
| + | Go to '''Services → Modbus → MQTT Gateway''' and there: |
| | | |
− | If you have familiarized yourself with the configuration scheme and have all of the devices in order, you can start configuring your routers using instructions provided in this section.
| + | # '''Enable''' the '''instance'''; |
| + | # '''Enter Host''' (copied from flespi connection settings without 'wss://' and port); |
| + | # '''Enter Username''' (Copied from flespi Connection settings generated '''token'''); |
| + | # '''Enter Password'''. |
| | | |
− | If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should >turn on "Advanced WebUI" mode</b>. . You can do that by clicking the "Basic" button under "Mode", which is located at the top-right corner of the WebUI.

− | ===RUT 1=== | + | ===Configuring Serial Gateway=== |
| ---- | | ---- |
− | ====Mobile Utilities configuration====
| + | Under the MQTT Gateway configuration, create the Serial Gateway: |
| + | # Enter the '''desired device ID'''; |
| + | # Select the '''desired serial interface'''. |
| | | |
− | * Log into Router 1 WebUI;
| + | [[File:Serial gateway config.png|border|center|class=tlt-border|868×308px]] |
− | * Go to the '''Services → Mobile Utilities → SMS Utilities''' page;
| |

| |
− | * Add new instance ('''3''');
| |
| | | |
− | [[File:SMS utils add.png|border|center|class=tlt-border|1004x1004px]]
| + | ===Configuring Flespi.io MQTT Broker=== |
| + | ---- |
| + | '''Log in''' or '''create an account''' on '''https://flespi.io'''; |
| | | |
− | After this you should redirected to configuration page for that rule:
| + | #Navigate to '''MQTT Board''' on the '''left side''' menu; |
− | [[File:SMS utils SMS config.png|border|center|class=tlt-border|1004x1004px]]
| + | #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''; |
| + | #In the opened window, press '''"Get flespi token"''' to generate a username; |
| + | #Enter the '''Client name'''; |
| + | #Copy the Host address; |
| + | #Copy '''Username'''; |
| + | #Create a '''password'''. |
| | | |
− | # '''Open General''' tab;
| + | Once done, save all the changes. |
− | # Check '''Enable''';
| + | [[File:Flespi board.png|border|center|class=tlt-border|1102x729px]] |

| |
− | ====I/O Juggler configuration====
| |
− | The I/O Juggler is a feature that provides the possibility to create automated rules that perform certain actions based on Input state changes and other conditions. You can learn more about it [[RUT955_Input/Output#I.2FO_Juggler|here]].
