I am developing an IoT application using FIWARE IoT Agent-JSON and Mosquitto. I create test devices, assign sensors to these devices, and publish data for these sensors via Mosquitto. I can correctly see the attributes of the sensors connected to the devices in the IoT Agent’s iotagentul.devices and iotagentul.EysDevices tables in MongoDB. However, in the orion-acd table in the Orion Context Broker, I see all the sensor attributes published via Mosquitto, while I only want to see the attributes of the sensors I have connected to the devices.

In Orion Context Broker, I only want to see the attributes of the sensors connected to the devices. Sensor attributes published via Mosquitto but not connected to the devices also appear in this table. I’m curious about the reason and solution to this situation.

Question 1: What should I do to prevent sensor attributes that come via Mosquitto and are not connected to devices from appearing in the Orion table?

Quesiton2 :What changes do I need to make to the IoT Agent or Orion configuration to resolve this issue?

I would welcome any help. Thanks!
