Beginner-friendly BACnet/IP troubleshooting from a Linux machine.
Designed for the situation where you temporarily shut down your normal BACnet/IoT application, start BACpypes3 directly on the BAS network, and determine whether BACnet devices, routers, BBMDs, and points can actually be reached.
Example of the BACpypes3 shell:
$ python -m bacpypes3 --address 192.168.204.11/24 --route-awareBuild a transparent, testable, human-in-the-loop Energy Management and Information System based on recognized EMIS practices.
This repository supports monthly utility analytics, interval energy analysis, data quality, benchmarking, demand, cost, carbon, findings, M&V, and optional future FDD and EnergyPlus integrations.
Audience: agents / engineers reviewing Plots validation cards and FDD DOCX.
One section per cookbook rule, grouped by mechanical family (same order as sidebar / Results). Each chart plots required (+ optional) roles present on the mapped frame, plus a confirmed-fault swim lane.

Goal: Build Open-FDD skills around Arrow-native HVAC fault detection, PyArrow, DataFusion SQL, Parquet, Rust migration, and future edge-to-central analytics.
Note: I did not find a widely recognized official Apache Arrow Foundation certification. The best path is a practical Arrow/DataFusion/data-engineering learning stack.

It is structured by equipment type, starting from the zone level and moving up to the central plant. Within each category, the rules are ordered by difficulty to implement: starting with the "low-hanging fruit" (simple boolean logic, schedules, and basic setpoint math) down to the more complex FDD rules (requiring thermodynamic models, enthalpy, or network-level data rollups).
These rules apply across multiple equipment types and rely on simple binary states, schedules, or BAS overrides, making them the easiest FDD rules to deploy.
A beginner-friendly experiment showing how a Graph Neural Network-style idea could be used for smart building / HVAC / BACnet fault detection.
This is not a production machine learning system. It is a simple teaching demo that uses made-up HVAC data, a small building graph, and probability-based fault scores to show the basic idea behind graph-based FDD.
Most HVAC fault detection starts with flat time-series data:
Generate cinematic, human-sounding AI dialogue for game cut scenes using Microsoft Neural Voices, completely scriptable from Python.
The script takes a dialogue script with two characters, generates separate voice lines, then merges them into a single cutscene_edge.wav ready for Unity, Unreal, Godot, etc.
⚠️ This uses Microsoft’s neural TTS over the internet via Edge-TTS. Text is sent to Microsoft’s service; audio comes back. No API key required.
Works great with:
