Question:
Fiware-Orion - How to work with attributes values history (lists of values)
Description:
I want to register some entities in my Orion instance and keep the history of attributes values in a way I can get the list of values of this attributes.
For example, a sensor S1 measuring temperature of a room hourly should keep a list of values in its temperature attribute in a way that every new update should be added in the end of the list.
The update operation I am doing now only updates the value, without adding it to some "list". I've read the documentation, but I did not find out some useful information about this. Does anyone have suggestions?
