What You Need

Flowstate CL260 edge node / hubIncluded in kit

Customer provides:

1
Connect device to network
Connect the MQTT device to the plant network via WiFi or Ethernet. Ensure it can reach the MQTT broker (Flowstate hub or HiveMQ Cloud).
2
Configure broker connection
On the device, set the MQTT broker address to the Flowstate hub IP (10.0.100.10:1883 for local, or HiveMQ Cloud endpoint for cloud). Set client ID to a unique value.
3
Set TLS (if cloud broker)
For HiveMQ Cloud, enable TLS 1.2+ on the device. Port 8883. Provide username/password credentials.

1
Configure publish topic
Set the device to publish on a topic following the UNS pattern: spBv1.0/{GROUP_ID}/DDATA/{EDGE_NODE}/{DEVICE_ID} for Sparkplug B, or a custom JSON topic.
2
Set payload format
Sparkplug B (preferred): device publishes protobuf-encoded payloads. JSON (fallback): publish JSON objects with key-value metric pairs. The Flowstate hub auto-detects format.
3
Configure QoS and retain
Set QoS 1 (at-least-once) for telemetry data. Retain = false for live data, retain = true for status messages.

1
Check broker connection
On the Flowstate hub, run mosquitto_sub on the device's topic. Verify messages arrive at the expected interval.
2
Dashboard check
Device appears in Flowstate. If using Sparkplug B, auto-discovery creates the asset automatically on DBIRTH.

Configurable — any metric the device publishes

Sparkplug B: auto-discovered from DBIRTH certificate

JSON: mapped via Flowstate topic-to-metric template

Common: temperature, humidity, pressure, status, counters
