Descripció
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 heightclass="custom-class"– add a CSS hookmode="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.

PMF
-
Does this replace my MQTT broker?
-
No. MQTT-Plug is a viewer and frontend. You still need an MQTT broker.
-
Which brokers are supported?
-
Any MQTT broker that supports WebSockets, including Mosquitto, EMQX, HiveMQ, and managed services.
-
Can I use this for production systems?
-
Yes, provided you follow standard MQTT security practices. For large-scale or multi-tenant systems, a managed broker is recommended.
-
Is JavaScript required?
-
Yes. MQTT-Plug uses browser-based WebSocket connections for live data.
