I replicated the APS DataViz Extensions Demo and I have used my own Model URN.
For the Model GUID, I left it an empty string. All other extensions (Sensor List, Sensor Detail, and Sensor Heatmap) works.
I have adjusted my iot.mocked.js code to suits the ObjectID and coordinate of the objects where I want the sensors to be attached.
Despite all these efforts, the Sensors Logo or Sprites do not appear on the viewer.
Can anyone help me?
