2019-06-19 08:37:26 +0200 commented answer Device provisioning

Thanks. >the device message is received and the device ID is used to find the Device entity and the Device entity in turn has some reference to an Asset entity. If possible, pls explain in more details how it is done. A Device is created first and should then be ref:ed to Waste container.entity

Thanks, that is of course possible. I this case I meant within Fiware and using NGSI and possibly being covered by the security framewotk within Fiware.

I have newbie question, it is related to device provisioning. We have an IoT device that sends a message with information including provisioning information. Let say that this device is used to make a connected Wastebin.

So I assume that the provisioning in this case includes both to map the protocol attributes (sent by device) to attributes in a Device Entity as well as to an Asset entity, in this case a Waste Container entity.

I mean for example hardware version, Device ID, serial number, device location would be related to the Device entity. But other attributes such as filling level, temperature, wastekind etc would be mapped to the Waste Container entity. So my question may be very trivial, but how is that mapping done when we have a "connected" Asset that then inludes at least two entities (Waste Container and Device). I would assume that the device message is received and the device ID is used to find the Device entity and the Device entity in turn has some reference to an Asset entity. And then protocol attributes could be mapped to both the Device and to the Asset entity referred to by the Device. But I do not know.

We are setting up a Fiware platform (NGSIv2) context broker and STH/QL. We also wanted to use a Fiware enabler for BI and initially planned to use Knowage. As I understand it is not possible anymore due to a new version of Knowage. Does any one know when it will be possible to use Knowage within Fiware?

With the risk of being vague but are there any other options similar to Knowage for BI within Fiware?

I am just started to lookiinto FIWARE. It looks great.

I am just curious if it is possible to create Device Groups. If we have many devices that we want to perform some action on a group of devices. Is there any entity for a group of devices?

I can see some group entites in the data model, for example
StreetlightGroup. It represents a group of streetlights being part of the same circuit and controlled together by an automated system. But this group has restrictions that the streetlights belong to same circuit.
