Chris is right, you must have a device (D:P:S) and register your "Thermostat" as a device with RMS. The DPS can be virtual if needed, but typically this would be the IO device you are using to communicate with your physical thermostat. For example if you are using a serial port on a NI master, the DPS could be that of the 5001:Port:System you are using to communicate with.

In this type of case, I prefer a virtual. Here's why: In a room I'm wrapping up now, for example, I have an Alcorn McBride audio player telling me whether it's playing on IO channel 1 of an NI-4100. I also have five motion sensors on channels 2 through 6. There might also be a Lutron room partition sensor on channel 7. In short, you can have multiple things that are logically unrelated, but reside on the same physical D:P:S. Using a separate virtual for each logical thing makes it easier for the user when he's looking at his RMS web pages, and it's approximately zero extra work for me, the programmer.
