Added MQTT support

Thanks Brian. Currently the page only has a “Server” field. What I am saying is that we should have a total of 4 text boxes:

  1. Server (already there)
  2. port number
  3. Username
  4. Password

Also, does the component you are currently use support QoS? If so, you may also want to add a 5th text box for that and perhaps have it default to “0”. QoS currently only supports these 3 options:

0: The broker/client will deliver the message once, with no confirmation.
1: The broker/client will deliver the message at least once, with confirmation required.
2: The broker/client will deliver the message exactly once by using a four step handshake.

Thanks
