Apparatus and associated methods relate to transformations of data provided by an Internet of Things (IoT) device. A processor defines a data transformation corresponding to data transmitted by the IoT device in an IoT system. The data transformation includes a definition of a transformation of data from a first format to a second format and an identification (ID) of the IoT device. The processor then compiles the data transformation to produce compiled executable code for performing the data transformation. The processor registers the compiled executable code for the data transformation as an available transformation for various components of the IoT system. The processor facilitates execution of the compiled executable code so as to perform the data transformation upon a data stream provided by the IoT device.
