Question:
How to detect sudden increase or decrease in value for an event using proton run time?
Description:
I am developing an application using proton CEP and Orion Context Broker. I have sensor that updates the temperature and CEP gets the temperature update as an event. I want the CEP to produce an alert if there is a difference of 10 than the last temperature.
For example:
The last update from sensor is 35. If the next update is less than 26 or greater than 45 I need CEP to produce an alert.
How can I write a rule to achieve this?
