Hi everyone,

I have received the following JSON message on my mosquitto MQTT broker:

The issue is that I am not getting temperature, sensor, and humidity data to my Ignition Engine module.

I have checked the configuration settings, and I can't figure out what I'm missing. I'm using Mosquitto as an MQTT broker, and the Ignition MQTT engine indicates that I have a connection.

What am I missing here?

Thanks in advance

My guess is you need to set up the custom namespace. By default, the Engine is only looking for the 4 default namespaces (2 of which are Sparkplug B), but to subscribe to your custom topic, you'll need to configure the custom namespace for it.
