BACnet is THE dominant protocol in the Building Automation Industry. The protocol specification is published by ASHRAE and costs a small fee. It is the prime reference if you wish to develop software to talk BACnet, but is rather formal and difficult to work with. It has a very steep learning curve. This Wiki is a resource for programmers who wish to implement a BACnet stack. Code and protocol hints are welcome. Descriptions of messages, BACnet services and other pointers are welcome too.
Please remember that the BACnet Specification is copyrighted material, and no cut & paste copies of the specification can be hosted here. Original interpretations, in a different format, are OK.
The best way to use this wiki is to use the search box on the left to search for the topic of interest.
