WHAT IS GRMS?
Guest Room Management Systems (GRMS) are hospitality-specific platforms that unify lighting, climate control, motorized shading, and guest services into a cohesive experience. Unlike generic building automation, GRMS is designed around the unique requirements of hotels — guest comfort, operational efficiency, and energy management.
Modern GRMS integrates with Property Management Systems (PMS), enabling automated welcome sequences on check-in, intelligent setback when rooms are unoccupied, and seamless coordination with housekeeping and maintenance operations.
PRIMARY FUNCTIONS
Welcome Sequence
Automatically activate preset lighting, climate, and shading when guest checks in
Occupancy Control
Detect room occupancy via key card and adjust systems for energy savings
Scene Control
Pre-programmed lighting scenes: Welcome, Relax, Work, Sleep, All Off
Climate Integration
Coordinate lighting with HVAC for unified comfort and efficiency
DND/Service
Do Not Disturb and Make Up Room indicators with housekeeping integration
Maintenance Alerts
Real-time diagnostics and automated maintenance notifications
TYPICAL SCENE CONFIGURATIONS
| Scene | Lighting | Temperature | Shades | Trigger |
|---|---|---|---|---|
| Welcome | 100% | 22°C | Open | On Entry |
| Relax | 40% | 23°C | Half | Manual |
| Work | 80% | 21°C | Open | Manual |
| Sleep | Off | 20°C | Closed | Manual |
| All Off | Off | Setback | Last | On Exit |
Scene configurations are customized per property to match brand standards and guest expectations.
ENERGY SAVINGS BY OCCUPANCY
Occupied Room
Guest-selected scenes
Unoccupied (Card Out)
Setback mode, lights off
Extended Absence
Deep setback, minimal systems
Check-out
Full power down except maintenance
Typical Hotel Energy Savings: GRMS implementations deliver 30-45% energy savings across the property through intelligent occupancy-based control and centralized scheduling.
INTEGRATION POINTS
CRITICAL PRINCIPLE
Never force GRMS to directly control individual lighting fixtures. Use proper gateway architecture (GRMS → DALI Gateway → Fixtures) to maintain system independence and reliability.
