BAC0 is an asynchronous Python 3 (3.10 and over) scripting application that uses BACpypes3 to process BACnet™ messages on an IP network. This library provides simple commands to browse a BACnet network, read properties from BACnet devices, and write to them.

Python is a simple language to learn and a very powerful tool for data processing. Coupled with BACnet, it becomes a great tool to test devices and interact with controllers.

BAC0 takes its name from the default IP port used by BACnet/IP communication: port 47808 (0xBAC0).

BAC0 is made for building automation system (BAS) programmers. Controllers used in this field are commonly called DDC Controllers (Direct Digital Control).

Typical controllers can be programmed in different ways depending on the manufacturer (block programming, basic scripts, C code, etc.). BAC0 provides a unified Python interface to interact with those controllers once their sequences are built.

BAC0 allows users to easily test an application even if sensors are not connected to the controller. Using the out_of_service property, it's simple to write a value to an input so the controller will behave as if an input is connected.
