MQTT Adapter

Subscribe to MQTT topics for inbound telemetry.

MQTT adapters connect in-process to an MQTT broker and subscribe to one topic per tag.

Tag addresses

Each tag address is the MQTT topic (no wildcards + or #).

Tips

  • One topic per tag — design UNS tag codes separately from topic hierarchy if needed
  • Use Test connection on the device detail page before adding many tags
  • Quality and timestamps come from the payload per adapter contract
