Connect to MQTT (Servers)

The app allows you to configure servers to connect to (servers in this context are the MQTT Brokers) to publish or subscribe to an MQTT queue.

Both protocols further support secure (TLS) and unsecure communication. Brokers listen on specific ports for each protocol. While there are some standard ports, brokers may use any port of their choice (which they will specify in their documentation). Private brokers also require authentication credentials, either a user id and password, or certificates.

To create a server enter the following details in the form:

• Name
  A short name to identify the server.
• Description
  A short description of the server.
• Protocol
  Select from the list of supported protocols.
• IP Address
  Optional, can be used if you are running a local server.
• Broker FQDN
  Fully Qualified Domain Name similar to those in the list above.
• Port
  A standard port is pre-entered based on the selected protocol but can be edited.
• MQTT URL
  This is the complete url with the protocol, FQDN, port, and required suffixes. It is pre-generated based on the values entered but can be edited as specified in the broker documentation.
• User Id
  Optional, generally required for private brokers.
• Password
  Optional, generally required for private brokers along with user id.
• Enabled
  The server is enabled by default but can be disabled if you don’t want to use it for a while.

You can connect to and disconnect from servers from the server list page.
