BACnet Integration
Expose EpiSensor energy data as BACnet objects for seamless building management system interoperability.
The Standard for Smart Buildings
BACnet (Building Automation and Control Networks) is an ISO/ASHRAE standard protocol designed specifically for building automation. It is the preferred integration path for facilities teams and BMS engineers who need energy data to sit alongside HVAC, lighting, and fire safety systems in a unified building management environment.
By exposing EpiSensor data as native BACnet objects, facility managers can monitor energy consumption in the same tools they already use to manage their buildings, without adding another dashboard or platform to their workflow.
How It Works with EpiSensor
The ZGW-10 Gateway runs a BACnet IP server that presents each sensor measurement as a BACnet Analog Value or Analog Input object. When the BACnet service is enabled, the gateway announces itself on the BACnet network and responds to Who-Is/I-Am discovery requests, allowing any BACnet client or BMS head-end to discover and subscribe to EpiSensor data points automatically.
Each BACnet object includes properly configured properties: Object_Name, Present_Value, Units, Description, and Status_Flags. Object identifiers are auto-assigned based on sensor serial numbers and measurement types, and can be remapped if your BMS requires a specific numbering scheme. The gateway supports COV (Change of Value) subscriptions for event-driven updates, reducing network traffic compared to continuous polling.
Key Features
BACnet IP Native
Full BACnet IP server implementation with Who-Is/I-Am discovery, ReadProperty, ReadPropertyMultiple, and COV subscription support.
Auto Object Generation
BACnet objects are created automatically as sensors join the network. No manual object configuration required for standard deployments.
COV Subscriptions
Support for Change of Value subscriptions enables event-driven data delivery, reducing network overhead and providing faster response to threshold events.
Custom Object Mapping
Remap object identifiers, names, and descriptions to match your BMS naming conventions. Export object lists for import into BMS configuration tools.
Engineering Units
Each object reports proper BACnet engineering units (kWh, kW, V, A, Hz) so your BMS displays values correctly without manual unit configuration.
Use Cases
Unified Building Management
Add granular energy sub-metering data to your existing BMS from Honeywell, Siemens, Schneider Electric, or Johnson Controls. View energy data alongside HVAC and lighting in a single pane of glass.
Energy Optimisation
Use real-time energy data within BMS control sequences to optimise HVAC schedules, identify equipment faults, and reduce peak demand through automated load shedding.
Green Building Certification
Provide the granular energy data required for LEED, BREEAM, and ISO 50001 certification. BACnet integration ensures data is available in the format auditors and building operators expect.
Getting Started
Enable the BACnet IP service on the ZGW-10 gateway through the web interface or the Core management platform. Assign a BACnet device instance number and ensure the gateway is on the same subnet as your BMS, or configure a BBMD (BACnet Broadcast Management Device) for cross-subnet communication. The gateway automatically creates BACnet objects for all connected sensors.
Once enabled, your BMS should discover the gateway within seconds via Who-Is broadcast. Add the discovered objects to your BMS points list and begin trending energy data immediately. For large deployments, export the object list as a CSV to bulk-import into your BMS configuration tool.
