Can't make "AI on the edge" work with Node-Red

[mimijojo]

AI on the edge (Release: v13.0.7 (Commit: 304b9e0)) up and running on my ESP32-CAM. Cfr attached config.ini
NodeRed 1.3.4 active on my Raspberry Pi. Cfr attached flows.json
Mosquitto MQTT is also active. "mqtt in"-node tested successfully. "mosquitto_pub -t gazmeter -m "test" "command displays expected payload msg (="test").

Issue : For some reason, I'm unable to send counter information from AI on the edge to my NodeRed using MQTT.

Cfr attached AI on the edge log file

Any hint ?

I do not have experience with NodeRed.

From AI on the edge it all looks ok ,and the messages get sent correctly to the broker.
You could use http://mqtt-explorer.com/ to check if the broker gets the messages.
If so, then the issue is somewhere on the NodeRed side, maybe you subscribed wrong or the wrong topics?

Thanks for your reply.
I tested my config with the http://mqtt-explorer.com/ tool. This works as well as it works with my "mosquitto_pub -t gazmeter -m "test" " test.
So I'm still stuck.
I guess probably some specific MQTT "AI on the edge" - MQTT NodeRed mismatch issue, but I can't find what exactly.
Any other hint ?

does the NodeRed receive your test messages?

maybe you better ask in a NodeRed forum.

My NodeRed displays correctly the payload test msgs I'm sending with both http://mqtt-explorer.com/ tool and mosquitto_pub.
So it sounds more like MQTT issue specific to AI on the edge.
I could indeed raise this issue on a NodeRed forum, but I'm not sure how to phrase it, so they don't push back to an AI on the edge issue.

Solution found ! Value to be configured in "Topic" field of Node-Red was : "gazmeter/main/raw ". Information found in "AI on the edge" log file.

thats great!

You might how ever prefer to use gazmeter/main/value! The raw can contain N if the recognition fails!
