Setting up WP-MQTT is easy. Simply supply your MQTT broker’s details and configure which WordPress events should trigger messages.
“MQTT is a machine-to-machine (M2M)/”Internet of Things” connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport.” (from mqtt.org)
A number of events are predefined. Simply check the right checkbox and fill in the message’s subject and text.
<ul>
<li>Pageview</li>
<li>User login</li>
<li>Failed user login</li>
<li>Post published</li>
<li>Page published</li>
<li>New comment</li>
</ul>
Other events can be added using the “custom events” section. This allows you to use any WordPress hook (actions and filters) to trigger messages.
