POTAR

MQTT-Plug brings live MQTT data directly into WordPress using secure WebSocket connections. 
It is designed for developers, IoT experimenters, and small production deployments that want real-time visibility without building a custom frontend.
Unlike traditional MQTT tools, MQTT-Plug focuses on embedding live data into WordPress pages, posts, and dashboards, while keeping credentials safe and configuration simple.
<h3>Key Features</h3>
<ul>
<li>Connect to MQTT brokers over WS/WSS</li>
<li>Live message stream and event log</li>
<li>Topic-based subscriptions</li>
<li>Shortcode-driven embeds</li>
<li>Works with public or authenticated dashboards</li>
<li>Designed for modern MQTT backends (Mosquitto, EMQX, HiveMQ, The-Link-Builders, managed brokers)</li>
<li>No external Node services required</li>
<li>Lightweight; no tracking, no telemetry, no lock-in</li>
</ul>
MQTT-Plug is infrastructure-agnostic. You control your broker, topics, and data flow.
<h3>Configuration</h3>
In Settings → MQTT-Plug, configure:
<ul>
<li>Broker host</li>
<li>WebSocket port</li>
<li>TLS / secure connection (WSS)</li>
<li>Username and password (if required)</li>
<li>Base topic or subscription filter</li>
<li>Debug logging (optional)</li>
</ul>
All credentials are stored using WordPress options and are never exposed to public users unless explicitly enabled.
<h3>Usage</h3>
Basic shortcode:
[mqtt_plug]
Optional attributes:
<ul>
<li><code>height="520px"</code> – set container height</li>
<li><code>class="custom-class"</code> – add a CSS hook</li>
<li><code>mode="observer"</code> – server-fed or read-only views (if enabled)</li>
</ul>
Example:
[mqtt_plug height=”600px” class=”iot-dashboard” mode=”observer”]
<h3>Security Notes</h3>
<ul>
<li>Public pages should not use live credentials.</li>
<li>Use observer or server-fed modes for public dashboards.</li>
<li>Always prefer WSS when exposing MQTT over the internet.</li>
<li>Rotate credentials regularly for production systems.</li>
</ul>
MQTT-Plug does not open inbound ports on WordPress and does not proxy MQTT traffic through the server unless explicitly configured.
