About this tool.
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

- 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
