Lighting Data into Building Automation
Turn your Koolmesh lighting network into a practical source of room-level building data.
Room-Level Visibility for Your BMS
Many building-management platforms control plant, HVAC, schedules and alarms but have limited visibility of real-time conditions inside individual rooms.
Structured room-level information
What’s Actually Happening in the Room
- Occupancy and presence
- Daylight lux levels
- Lighting status
- Other sensor status
The challenge is not simply collecting more data. It is making useful room-level data available to the BMS in a structured, project-ready format.
Why Start with Lighting
Lighting infrastructure already reaches almost every room, zone and floor of a building—exactly where occupancy, daylight and space use occur.
That makes the lighting network a natural starting point for bringing real-world room-level data into wider building automation.
From Lighting to the BMS
Through HBGW04/R, selected occupancy, daylight, lighting, device-status and supported energy data can be made available to compatible building-management platforms via BACnet/IP, Modbus TCP/IP or MQTT.

What the Lighting Network Can Share
A connected lighting network can give the BMS a clearer view of connected spaces—from occupancy and daylight to lighting operation and supported device data.
Space Use
Occupancy and presence across rooms and zones.
Daylight
Daylight lux levels and ambient brightness through the space.
Lighting Operation
Lighting status, dimming levels and colour temperature where available.
Energy Use
Consumption and metering data from compatible devices.
Device Health
Device status and selected fault information.
Zones & Scenes
Information and control at room, zone, group or scene level.
From Room Data to Building Action
Each available room-level input can support a practical building-level outcome when used within the BMS control strategy.
Occupancy
Demand-Based HVAC
Adapt heating, cooling and ventilation to actual room use.
Occupancy over time
Space Utilisation
Understand when and how rooms and areas are being used.
Out-of-Hours Occupancy
Operational & Security Alerts
Flag unexpected activity outside normal schedules.
Room-Level InputOccupancy data provides a clearer view of how spaces are actually being used.
Supervisory UseSelected data can support dashboards, reporting, alerts and operational review.

Lighting Control / Writable Points
Whole-Building Automation
Coordinate lighting with HVAC, schedules, modes or other building systems.
Available data depends on the connected Koolmesh devices, gateway configuration, firmware version and agreed project scope. The BMS determines the final logic and response.
Where This Route Fits
Turn a lighting project into a practical building automation opportunity.
Upgrade Existing Lighting Infrastructure
Use a lighting refurbishment or retrofit as an opportunity to bring room-level data into the wider building automation system.
Bring More Data into an Existing BMS
Add occupancy, lighting and sensor data from the spaces the BMS may not currently see.
Connect Lighting from the Start
Make the lighting network part of the wider building automation strategy in new-build projects.
Extend Your Luminaire Offering Beyond Lighting
Use connected sensors and controls to make room-level data from your luminaires available to the wider BMS.
Connect the Lighting Network to the BMS
HBGW04/R provides the multi-protocol connection between the Koolmesh Bluetooth Mesh lighting network and compatible building-management or supervisory platforms.

Connects Koolmesh Bluetooth Mesh lighting systems with building-management and supervisory platforms.
BACnet/IP | Modbus TCP/IP | MQTTIntegration Questions
Every project has a different lighting installation, BMS, network and point requirement. These answers establish the starting point.
Can this be added to an existing Koolmesh lighting installation?
Yes, depending on the existing devices, gateway compatibility and project configuration. This makes it possible to extend an existing lighting installation into building automation without starting again from scratch.
Can it integrate with any BMS?
Integration is possible with BMS and supervisory platforms supporting BACnet/IP, Modbus TCP/IP or MQTT. The required points, mapping, network access and integration route should be confirmed for each project.
Where does the automation logic sit?
Koolmesh makes lighting and room-level data available to the BMS. The BMS remains the supervisory layer and determines how that data is used within the wider building automation strategy.
Can the BMS control the lighting system?
Selected commands and writable points may be supported where the connected device, gateway configuration, firmware and agreed project strategy allow. The final point list and control hierarchy must be confirmed during project review.
