2020-05-08 11:55:58 +0100 asked a question DeviceModel - Device

"A DeviceModel captures the static properties of a Device." Can I interpret that a DeviceModel is a "class" of Devices: meaning I can have several Devices ("instances") with the same DeviceModel: DeviceModel 1 -> N Device?

Or is there a 1:1 relationship between DeviceModel and Device?

Thanks.

Hi,

What is the manner to model a gateway device to which several end devices are connected?

My idea was: For the Gateway: DeviceModel -> category -> network All End devices: Device -> refDeviceModel (the above defined DeviceModel)

Is this correct?

Thanks.

2019-12-03 12:06:57 +0100 asked a question IoT Agent - HTTP & MQTT command (southbound)

Hello,

To me it's not clear if a device needs to take the initiative (pull) to get southbound/commands from the IoT Agent (http transport) or the IoT Agent takes the initiative (push) to the device?

For MQTT I suppose the IoT agent subscribes to the MQTT (Mosquitto) broker and subscribes and/or publishes to the MQTT broker?

Thanks for the clarification.

What is the best approach for visualizing geo location data (e.g. polyline, polygon layers geo data in a leaflet app) with Context Broker: get the data directly from context broker or using something like geoserver between context broker and the data visualization?

Thanks.
