MQTT not send data


I try to send data with a simple nodeJs application. All seem good but I can’t find data on the monitor

I join some screenshot in this post.

Tanks you for your help


Seems like a payload format issue. Let’s use the error topic to get the error. Read the following page and subscribe to this topic using your MQTT desktop application.

If you still need help, copy and paste the error message you receive from this topic.


Its really knowledgeable thread buddy thanks for sharing the knowledge :slightly_smiling_face:
