Your MQTT Dashboard

Welcome to your built-in MQTT toolbox. From here you can browse every topic on your broker, publish test messages, and check which clients are online — all without leaving the Coreflux HUB. Two widgets are ready for you: Data Viewer for topics and messages, and Connected Clients for monitoring connections.

No need to install external tools — the Data Viewer is built right into the Coreflux HUB.
