MQTT Agent CONNECTED, but Asset Attribute not updating via external publish (MQTT Explorer)

Agents, Protocols and APIs

Hi everyone,

I am having an issue where incoming MQTT telemetry is not updating my asset attributes in the Manager UI. My MQTT Agent shows as CONNECTED, and I can confirm messages are being published to the broker, but the values are not mapping to the asset.

My Environment:
Running a local OpenRemote instance via Docker on a Windows PC.
Testing external publishes using MQTT Explorer.

Steps Taken:

  1. Created an MQTT Agent asset.
    host: localhost
    port: 1883
    clientID: client123
    agentStatus: Successfully shows as CONNECTED.
  2. Created a Thing asset named test_device with a temperature attribute (Type: Integer).
  3. Added an MQTT Agent Link to the temperature attribute:
    Selected the newly created MQTT Agent.
    Subscription Topic: device/thing/temperature
  4. Connected MQTT Explorer to the same local broker.
  5. Published a message from MQTT Explorer:
    Topic: device/thing/temperature
    Format: raw
    Payload: 28

The Issue: The message successfully registers on the broker in MQTT Explorer, but the temperature attribute on the test_device asset in OpenRemote remains completely blank.

Good afternoon @shyam209 ,

This is quite wrong; you are using an MQTT agent to connect your device to OpenRemote. Agents are used to connect to other services to then collect data; so the MQTT agent would be used to connect to a foreign server and collect data, not the other way around.

Please read this guide that explains how to connect your device to OpenRemote.

Hope this helps!

All the best,
Panos

Hi Panos,

Thank you for the clarification. I completely misunderstood the architecture and was trying to use the MQTT agent to act as the direct listener for my local setup, rather than as a bridge to an external server.

Thanks for pointing me in the right direction.
