I created a Thing Shape, Thing Template and a Thing to house my data. I successfully see the temperature property bound to my Thing. However, I want to build a mashup that shows this temperature value on an LED display, how would I do that? Which entity do I add?
I believe you have access to eLearning correct? I recommend you take a look at Part 1 of Thingworx fundamentals. There is some video content with that course, that covers the creation of Mashups, adding widgets and services to it, and binding them together.
