Day 3 – Python Strings + Your First BACnet Read Request with BAC0 | Talking to Real Devices

Welcome to Day 3 of the BACnet with Python for Building Automation Techs and Engineers course. Today is a big step. We learn Python strings — and then immediately use them to talk to a real BACnet device. Up until now we’ve been setting up Python and learning basic syntax. Today we connect that knowledge to something practical: building a simple BACnet read request using BAC0. Because in building automation… everything is text. Device addresses Object types Point names Requests Descriptions Units They’re all strings. So before we start scanning networks and logging telemetry, we need to understand how strings work and how to build them dynamically. In this lesson we cover: • creating strings with quotes • concatenating strings • indexing and slicing text • measuring string length • formatting readable output messages • building request strings programmatically Then we put it all together and make our first real BACnet read using BAC0. We: • connect to the network • send a read request • read present-value • read description • read units • print a clean formatted message Something like: The sensor reading is 72.3 °F for the Zone Temperature. That’s your first real BAS script. From here, everything builds on this pattern. If you can read one point, you can read 100. If you can print one value, you can log a whole building.

If you’re an HVAC tech who wants to move from clicking points in a GUI to scripting your own tools… this is where it starts getting fun.
