Guest Room Automation Integration

The problem

Room control units manage lights, curtains and fan coils, but the front office and engineering cannot see room status or set unsold rooms to energy-saving mode.

Solution overview

MILESGO gateways collect data from guest room control units (RCU), fan coil units (FCU), KNX lighting actuators and panels, door contacts, occupancy and people-counting sensors over KNX / Modbus RTU / Modbus TCP, and deliver it to the BMS, third-party platforms (HTTP API), WEB HMI panels as BACnet/IP / MQTT / KNX. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

guest room control units (RCU)
fan coil units (FCU)
KNX lighting actuators and panels
door contacts
occupancy and people-counting sensors

Protocol path

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

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.
Write the control sequence (start/stop order, interlocks, set-points, fallback on communication loss) and have it approved before programming.
Commission in read-only mode first; enable write / control points only after the client approves each one.
Standardise one configuration template per equipment type so further sites are copied, not rebuilt.
Fix a site / asset naming convention before the first site so data from all sites can be compared.
Build and simulate the configuration off site (FAT) before installation to shorten time on site.

System architecture

Field layer: guest room control units (RCU), fan coil units (FCU), KNX lighting actuators and panels, door contacts, occupancy and people-counting sensors, connected over KNX / Modbus RTU / Modbus TCP. 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, third-party platforms (HTTP API), WEB HMI panels, which receives the data as BACnet/IP / MQTT / KNX. Remote access for maintenance runs over VPN rather than open internet ports.

System composition

Field devices: guest room control units (RCU), fan coil units (FCU), KNX lighting actuators and panels, door contacts, occupancy and people-counting sensors
Edge / integration: MILESGO protocol gateways and edge controllers
Upper systems: the BMS, third-party platforms (HTTP API), WEB HMI panels (BACnet/IP / MQTT / KNX)
Tools and commissioning: Web-based configuration, point table import/export (Excel), off-site simulation and on-site diagnostic tools

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

Consumption visible by area, system and time period
One view of all subsystems instead of separate vendor consoles
Configuration templates reused across sites
New equipment integrated by configuration, not custom driver development
