Hotel BMS Integration

The problem

Hotel plant, lighting, lifts and guest-room systems come from different vendors, so engineering cannot link occupancy to HVAC or see faults before guests complain.

Solution overview

MILESGO gateways collect data from chillers, air handling units (AHU), guest room control units (RCU), KNX lighting actuators and panels, lift controllers, electricity meters over BACnet/IP / Modbus TCP / KNX / Modbus RTU, and deliver it to the BMS, WEB HMI panels, third-party platforms (HTTP API) as BACnet/IP / MQTT. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

chillers
air handling units (AHU)
guest room control units (RCU)
KNX lighting actuators and panels
lift controllers
electricity meters

Protocol path

BACnet/IP / Modbus TCP / KNX / Modbus RTU → BACnet/IP / MQTT

Implementation checklist for the project manager

Where equipment only offers a vendor API or cloud, confirm access rights, data rate and costs with the vendor before design.
Freeze the point list and protocol mapping with the client before ordering hardware.
Agree BACnet device instances, network numbers and BBMD with the BMS contractor to avoid conflicts.
Fire and life-safety systems are monitored read-only; control stays with the certified fire system.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
Hand over configuration backups, point table, IP plan and as-built drawings, with a short operator training.

System architecture

Field layer: chillers, air handling units (AHU), guest room control units (RCU), KNX lighting actuators and panels, lift controllers, electricity meters, connected over BACnet/IP / Modbus TCP / KNX / Modbus RTU. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the BMS, WEB HMI panels, third-party platforms (HTTP API), which receives the data as BACnet/IP / MQTT. Remote access for maintenance runs over VPN rather than open internet ports.

System composition

Delivery steps

1
Site survey and point list
Inventory devices, protocols, register maps, panel space, power and network paths.
2
Design and point table sign-off
Map every point to the target protocol and system; agree it with the client and the upper-system contractor.
3
Configuration and FAT
Build the gateway configuration off site, simulate it and test against the signed point table.
4
Installation and wiring
Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.
5
SAT and alarm tests
Verify values against local readings, test every alarm and command end to end.
6
Handover and support
Hand over configuration backups, point table and as-built documents; train operators.

Customer value

One view of all subsystems instead of separate vendor consoles
Consumption visible by area, system and time period
Alarms reach the right person by SMS, email or messaging apps
Open interfaces (BACnet, Modbus, OPC UA, MQTT, HTTP) avoid lock-in to one vendor
