Hello and welcome!
Hmmm…like what applications? We’re creating an API that will give you access to your data points. Check this out too: Get sensor values in another app [workaround solution!] - #9 by Ian
There will be, not yet though. Designing it now. We are also working on a way to allow you to insert your own code into Cayenne, for example your python script.
Hope this helps!
See you around,
