HiveMQ provides the MQTT data stream that Grafana visualizes through its MQTT data source or via intermediate databases like InfluxDB.
HiveMQ brokers MQTT messages from IoT devices that are then written to InfluxDB for time-series storage and analysis.
HiveMQ and Node-RED form a common IoT data pipeline. Node-RED connects to HiveMQ as an MQTT client to subscribe to device topics, process messages, and route data to databases, APIs, or other services.
