Overview

The MQTT Broker driver connects Control4 to an MQTT broker (such as Mosquitto, HiveMQ, or other MQTT-compatible platforms). It manages the connection and provides pub/sub services to child drivers (switch, button, contact, etc.) that connect via the MQTT broker connection binding.

Features

  • Local network communication requiring no cloud services
  • Connects to any standard MQTT broker
  • Supports username/password authentication
  • Manages subscriptions for connected child drivers
  • Automatic reconnection on disconnect
  • Message caching for late-subscribing devices

System requirements

  • Control4 OS 3.3+
  • An MQTT broker accessible on the local network

    • JSONPath value extraction for complex JSON payloads
