I have a temperatur sensor as a thing in Thingworx. Now I would like to recognize how fast the temperature changed.
For example if the temperature increased by more than 3 Degrees in a period of one second I would like to fire an event (an alarm). Do you have any idea whether there is an elegant approach to do this?
My naive Idea would be a subscription that checks how much the temperature changed one second ago once a "data changed" event occurs.
Any help and tips are appreciated very much.
Maybe the Descriptive Analytics services Rate of Change or Number of Points with Change Rate Out of Range may help to some extent on this.
See the Help Center for more info: https://support.ptc.com/help/thingworx_hc/thingworx_analytics_8/#page/analytics%2Fda-overview.html%2...

Hope this helps
