Intro
MQTT is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. Connect your MQTT data to Domo using the MQTT Connector. MQTT shows your real-time data from hundreds of IoT devices, and lets you set alerts to be notified when time-sensitive metrics change.Prerequisites
No prerequisites are required to connect to your MQTT account and create a DataSet.Connecting to Your MQTT Connector Data
This section enumerates the options in the Details panes in the MQTT Connector page. The components of the other panes in this page, the Scheduling and Name & Describe Your DataSet, are universal across most connector types and are discussed in great detail in Adding a DataSet Using a Data Connector.Details Pane
This pane contains the details that help you to connect your MTTQ data to Domo.Field | Description |
|---|---|
| MQTT Broker Host | This field display the address of your MQTT Connector broker host. Click Copy Address button to copy the address. |
| Port to Connect Domo to MQTT | This field displays the port number that connects your MQTT Connector data to Domo. Click Copy Port button to copy the port number. |
| Certs Will Expire In | Select the number of years that you want the Certificates to work for. The certificates will expire after the selected number of years. Click Download Certs button to download the certificates. These certificates are required to connect a device to the Domo Broker. |
| Require username/password? (checkbox) | Select this checkbox if you wish to provide additional authentication by requiring MQTT Connector clients to send a username/password to connect to the Domo Broker. Certificates expires in 1 year. |
| Username | Enter the username provided by MQTT Connector client. (This field appears when you select the Require username/password checkbox.) |

| Update method | When Domo retrieves your data from the source, you can determine how that new data is imported into the current DataSet. For this connector we offer Append and Replace update methods. Append: This method takes your new data and adds it to your current DataSet. This may create duplicate data entries. Replace: This method will take your current DataSet and replace it with new data. Using this may result in some data loss. |
