Integrations

No new hardware. Connects to what you already have.

Voltpathio speaks BACnet/IP, Modbus TCP/RTU, and Project Haystack natively. Reads all six major US ISO/RTO market feeds at 1-second resolution. Writes demand and curtailment data back to your CMMS or BI tools via REST API. The protocol adapter runs in software — no on-site hardware, no BMS firmware updates.

BMS Protocols

Works with your existing BMS

No hardware replacement. Adapter layer connects to your current system and streams telemetry in real time.

BACnet/IP

Full BACnet/IP and BACnet MS/TP device discovery. Read/write object access via standard BACnet objects and properties.

Honeywell Niagara N4, Siemens Desigo PX, Johnson Controls NAE

Modbus TCP/RTU

Poll-based register reads for legacy equipment: chillers, boilers, VFDs, submeters, and energy meters without native BACnet.

Schneider Electric EcoStruxure, ABB, Eaton

Project Haystack

Semantic tagging aware — auto-maps Haystack-tagged points to Voltpathio's building model for immediate load-shaping enrollment.

Skyspark, WattNode, SkySpark Trio

Grid Market APIs

All six major ISO/RTO markets

REST API

Pull demand data into your BI stack or CMMS

The Voltpathio REST API exposes real-time demand readings, forecast data, curtailment event history, and savings calculations. Rate-limited at 60 requests/minute per building on Portfolio tier. Endpoints follow OpenAPI 3.0 spec — full documentation available in the platform dashboard.

JSON responses at 15-second and 1-minute interval granularity
Webhook push for demand events (configurable kW threshold trigger)
OAuth2 bearer token authentication per building scope
24-month historical interval data retention (Portfolio + Enterprise)

GET /v1/buildings/{id}/demand — JSON response
