AMPII is a simulator for the BACnet Web Services (BACnet/WS) protocol proposed in Addendum am to ANSI/ASHRAE Standard 135.

The primary purpose for writing it was to spur development of prototypes to test the protocol. However, it has a BSD license, so you can do whatever you want with it, even for commercial purposes.

Initially, this is just an implementation of the server side of the protocol. Future enhancements may include the ability to be a data-driven client simulator, and thus morph into a simple form of an automated testing tool.
