What's the status of the Legrand lighting occupancy → BMS + HVAC flow today?

All flowing. HVAC follows lighting occupancy is live. No blockers flagged.

THE REALITY

Legrand is brilliant at what it does. Useless at everything else your data + AI needs to touch.

Legrand runs lighting and shading beautifully at each site, but the occupancy and daylight data never reaches HVAC or the energy model, and a failed driver is noticed only on a walk-round.

The integration tool you've already tried probably can't fix it.

What Zapier + iPaaS reach

SaaS-to-SaaS. Useful, until it isn't.

Connectors for Legrand, Slack + a thousand other SaaS apps. Cheap + fast for the easy half of integration. Where they hit a wall:

Energy + ESG platforms needing live lighting-load, demand and daylight-harvesting data
HVAC and BMS that should coordinate with lighting occupancy and daylight sensing
CMMS work-order systems that should raise a job when a lighting circuit or driver fails
Data warehouses and AI agents needing live lighting, shading and energy history

What Rayven reaches

Energy, metering, ERP, work orders + AI. One platform.

The integration platform built for what other tools can't (or won't) reach - plus an AI data fabric, MCP server + app builder layered on top.

Legrand + every energy/EMS, work-order (CMMS) and ERP system
BACnet, Modbus, LonWorks, KNX, MQTT + custom-built connectors.
Files, legacy SQL, FTP + custom-built connectors
Real-time bidirectional sync, tier-aware + rate-limit-safe
AI Data Fabric, MCP, automation + custom apps included

WHAT YOU CAN BUILD

Legrand + Rayven: AI, automation + tools that reach every system you run.

4 examples of what Rayven customers run on Legrand + integrated systems. Built in weeks, not months.

Legrand lighting occupancy → BMS + HVAC

HVAC follows lighting occupancy

Occupancy and daylight sensing from Legrand controls flow into your BMS so HVAC conditions only occupied zones. Where you scope it, supervised setpoints trim empty space while fire and life-safety stay untouched.

Lighting load to the energy model

Lighting load, dimming and daylight-harvesting data stream into your energy model in real-time. Energy teams see lighting as a live, tunable load across the estate.

Snapshot of activity in the last 24 hrs?

47 events processed. 0 errors, 2 retries, all current.

Legrand fault detection → CMMS

Driver faults become work orders

A failed DALI driver or lighting circuit raises a job in your CMMS automatically, with the fixture and location attached. Maintenance replaces it before the complaint arrives.

Status check - is everything in sync?

All current. Last sync 38 seconds ago, no backlog.

BEYOND INTEGRATION

Integration is the start with Rayven.
Here's what comes with it.

Rayven isn't just a Legrand connector. It's the operational software platform underneath - so once Legrand is connected, four more capabilities come online by default.

AI-ready data layer (AI Data Fabric)

Legrand data joined with ERP, IoT + legacy - contextualised, unified and structured so AI models, agents and tools can use it without ETL prep work.
Learn more →

Live AI access (Rayven MCP)

Claude, ChatGPT + Gemini get live, governed access to Legrand and every other connected system. Your AI stops guessing - cites real Legrand records + numbers.
Learn more →

Automation + AI agents

Workflows + AI agents act on Legrand data without human intervention - escalate at-risk accounts, trigger operational work, auto-update forecasts, draft customer comms.
Learn more →

Custom apps + portals

Unified customer portals, ops dashboards, mobile field apps, partner portals - built on top of integrated Legrand data. No separate BI tool, no separate dev stack.
Learn more →

All on top of your existing stack. No rip + replace. Legrand stays Legrand. Rayven works on what you've already built. Specifically tuned for Legrand DALI and KNX lighting occupancy joined to HVAC and energy.

What is Legrand building control integration?

Legrand building control integration is the practice of connecting Legrand's lighting, shading and energy controls to the rest of your estate stack - energy, HVAC, work orders and AI - so lighting data drives the whole building. Rayven delivers it as part of an Industrial AI Data Fabric.

How does Rayven connect Legrand building control systems to other systems?

Rayven connects over DALI, KNX and BACnet from Legrand, Vantage and Nuvo controllers for real-time bidirectional sync. Lighting scenes, dimming levels, occupancy and energy all flow as first-class integration events. See the Rayven Platform for how the layers fit together.

What systems can Rayven connect Legrand building control systems to?

Rayven connects Legrand to 1,228+ systems including energy platforms, CMMS, ERP, and sibling BMS brands like Lutron Quantum and EcoStruxure Building Operation. Custom controllers are part of done-for-you delivery.

Does Rayven control or replace Legrand building control systems?

No. Legrand keeps controlling lighting and shading. Rayven reads its data and, where you scope it, writes energy and comfort setpoints back under supervision. Rayven never writes to fire or life-safety systems and does not replace your controls - it adds a real-time data and AI layer. See how the platform works.

What are the most common Legrand building control integration use cases?

Top use cases are HVAC following lighting occupancy, lighting load to the energy model, driver faults to CMMS and estate-wide AI. See the automations above for specifics.

What are the technical specifics of Legrand building control systems integration with Rayven?

Rayven connects to Legrand Building Control Systems over DALI, KNX and BACnet from Legrand, Vantage and Nuvo controllers, through per-protocol gateways, for real-time bidirectional sync. Lighting scenes, dimming levels, shading positions, occupancy and metered energy are mapped field by field into energy, CMMS, HVAC and AI targets. Authentication uses gateway and device credentials at the edge. DALI and KNX address spaces differ from BACnet, so Rayven maps each to a stable estate point model. Rayven reads continuously and, where you scope it, writes energy and comfort setpoints back under supervision; it never writes to fire or life-safety systems and Legrand stays in control of lighting. Occupancy is per-fixture and energy depends on metered circuits, so both are configurable inputs. Multi-site estates reconcile to one model via edge collectors, running on-prem or sovereign-hosted. Validated against Legrand, Vantage and Nuvo controllers alongside other BMS brands.
