FIWARE IoT Agent JSON with MQTT to connect devices and monitor changes, in version 3.7.0 of Orion, the system would only listen to and update the attributes that were explicitly added. However, in the latest versions of Orion and IoT Agent JSON, during my tests, I noticed that the system was also adding attributes that I hadn’t explicitly added and monitoring their changes. Why are these attributes, which I don’t intend to monitor via MQTT topics, being monitored by Orion? If this behavior persists, what is the purpose of declaring attributes when adding a device? Will only the features you want to watch be published on the MQTT topic?

When using Fiware IoT Agent JSON version 1.26.0, this issue does not occur; only the active sensors are written to Orion. However, when I upgrade to Fiware IoT Agent JSON version 3.3.0, all sensors are written to Orion instead of only the active ones. How can I prevent this?
