MQTT-Plug

Deskripsyon

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.

Key Features

• Connect to MQTT brokers over WS/WSS
• Live message stream and event log
• Topic-based subscriptions
• Shortcode-driven embeds
• Works with public or authenticated dashboards
• Designed for modern MQTT backends (Mosquitto, EMQX, HiveMQ, The-Link-Builders, managed brokers)
• No external Node services required
• Lightweight; no tracking, no telemetry, no lock-in

MQTT-Plug is infrastructure-agnostic. You control your broker, topics, and data flow.

Configuration

In Settings → MQTT-Plug, configure:

• Broker host
• WebSocket port
• TLS / secure connection (WSS)
• Username and password (if required)
• Base topic or subscription filter
• Debug logging (optional)

All credentials are stored using WordPress options and are never exposed to public users unless explicitly enabled.

Usage

Basic shortcode:

[mqtt_plug]

Optional attributes:

• height="520px" – set container height
• class="custom-class" – add a CSS hook
• mode="observer" – server-fed or read-only views (if enabled)

Example:

[mqtt_plug height=”600px” class=”iot-dashboard” mode=”observer”]

Security Notes

• Public pages should not use live credentials.
• Use observer or server-fed modes for public dashboards.
• Always prefer WSS when exposing MQTT over the internet.
• Rotate credentials regularly for production systems.

MQTT-Plug does not open inbound ports on WordPress and does not proxy MQTT traffic through the server unless explicitly configured.
