1. A computer-implemented method for automatic generation of a device program comprising: determining a controller from among a plurality of controllers displayed in a graphical user interface (GUI) on a user device communicatively coupled to a corresponding external controller; generating a user interactive pin layout in the GUI for the external controller; displaying in the GUI, a plurality of operations for execution by the external controller, wherein at least one operation comprises communicating data with an external data service; determining an operation from among the plurality of operations for the controller, wherein the determined operation comprises communicating data with an external data service; associating pins selected to parameters of the operation; receiving parameter data for the operation from at least one data entry field in the GUI; generating a program for the controller based on the user interactive pin layout, the received parameter data, and the operation; and sending the program for storage in a memory on the external controller.
