BACnet

BACnet is the default data driver for Open-FDD. Discovery, diy-bacnet-server, and the BACnet scraper are documented here. Swagger (diy-bacnet-server): http://localhost:8080/docs

Setup (do this before the platform scrapes data)

Recommended: data model

  1. Start the platform (including diy-bacnet-server) — e.g. ./scripts/bootstrap.sh.
  2. Discover devices and points — In the Config UI (/app/) use the BACnet panel: Who-Is range, then Point discovery per device. Or call the API: POST /bacnet/whois_range, POST /bacnet/point_discovery.
  3. Graph and data model — Call POST /bacnet/point_discovery_to_graph (device instance) to put BACnet devices and points into the in-memory graph and sync config/data_model.ttl. Create points in the DB via CRUD (set bacnet_device_id, object_identifier, object_name) or use GET /data-model/export → LLM/human tagging → PUT /data-model/import.
  4. Scraper runs automatically — The bacnet-scraper container (or tools/run_bacnet_scrape.py) loads points from the data model and polls only those. Configuration is via the frontend and data model only; no BACnet CSV in the default workflow.
