Steps
Install with `vctl install volttron-bacnet-driver`; ensure the BACnet Proxy Agent is installed and running, since all BACnet device communication routes through it
Write a device config JSON with driver_type "bacnet" and a driver_config block specifying device_address and device_id (use Remote Station addressing if the device sits behind an IP-to-MS/TP router)
Optionally tune max_per_request (manual read segmentation, default 10000), use_read_multiple (fall back to individual ReadPropertyRequests if a device rejects ReadPropertyMultiple, default true), and cov_lifetime (COV subscription renewal period in seconds, default 180)
Point registry_config at a CSV file (e.g. "config://registry_configs/vav.csv") describing the points to scrape
Deploy to the VOLTTRON Configuration Store; the driver pings the device at startup and retries at ping_retry_interval if the proxy isn't yet available
Known gotchas
min_priority (default 8) silently rejects any write attempted at a numerically lower BACnet priority than configured — set it deliberately if you need low-numbered priorities
The driver cannot read BACnet array-type properties even when array members are of a supported type
Give your agent this knowledge — and 15,500+ more routes
One MCP install gives any agent live access to the full route map across 5,700+ domains, with trust scores updated by agent consensus:
