iotagent-json | IoT Agent for a JSON based protocol

I'm running the Fiware IoT Agent example locally. The plan is to hook this up to some sort of Device and make a demo. I'm using request bin to inspect the requests sent from the IoT Agent.

After starting the environment with ./services start I'm calling this shell script to register a bell device in the agent and then trigger the "ring" command.

I am working on FIWARE IoTAgent-JSON. I want to perform device discovery by the same. My expectation from device discovery is that whenever a new device gets registered in IoTAgent-JSON, I receive a notification with device data. Is it possible? If yes, how can this be done?

I am using IOT-agent JSON with MQTT binding

I have a sensor-actuator registered in orion using iot-agent and I created the subscription.

If a third party application modifies a sensor value, orion must send iot-agent information and iot-agent to the device.

for example, if I have 3 attributes inside the sensor and one of them controls a valve.

In orion that attribute is true or false.

if the attribute is modified in orion must be sent to iot-agent and iot-agent to the device to close or open the valve.

extra information:

The software is two component of Fiware Generic Enable.

Is it possible?

I've deployed a FIWARE configuration to receive MQTT messages from TheThingsNetwork. The configuration uses IoTAgent-JSON, Orion and Cygnus, with a MongoDB backend for Cygnus.

The messages are correctly persisted to MongoDB. Unfortunately, the message data having a hierarchical structure, some parts of the message appear as strings in MongoDB, instead of embedded subdocuments.

This makes it difficult to query the data.

Here are the details:

The message format is defined by the TTN MQTT Data API.

I've defined an entity type on Orion as follows:

On my server I have Orion context broker and an IoT agent working in docker containers. I can register and update my entity using MQTT protocol no problem. But I would like to be able to send command to my device using the command system in the IoT Agent. In the Documentation, it says that when a command is registered, the IoT agent publish something in /apiKey/EntityID/cmd. However, when I do so, I don't have anything published. The entity is updated properly (I can see the status of the command going to PENDING, and positive LOG telling me that everything is OK. But nothing is published on my MQTT topic.

Here is my docker-compose.yml file:
