2020-02 Enrichment of events and messages
By default, the Bosch IoT Things service will notify all consumers with read permission on a specific thing about all changes applied to the thing entity. This type of signal is also known as ‘change event’.
But what, if your consumer needs additional data related to that thing, in order to get “more meaningful” notifications?
The answer is: using the new possibility to enrich events and messages.
The new approach will help your application to get additional data - like attributes, or feature properties - on each event. Although enriched events are a bit “bigger”, they reduce the traffic, as your consumer does not need a second request-response for the “extra” data.
How to use it?
You can add e.g. attributes or feature properties of your things, which are not included in the original payload, but are helpful for your consumers, by using the new parameter
For persistent connections you can specify the settings at the Target section.
What about filtering?
In case your application prefers to only be notified upon a specific kind of events, you can apply filtering and thus help to reduce traffic load.
The new enrichment query parameter
extraFields and the event
filter can be used together.

2020-01 New chart view in Things UI
The Things UI includes a new chart view which displays thing property data collected over the time.
This view helps to understand IoT device sensor data during the development of IoT solutions. The shown data is live data updated in thing properties and is only collected during the time when the dashboard view is open. The data series is not stored.
How to use it?
To open the Things tab > click on a specific thing > Chart View.
