GRMS Integrations for Smart Hotels
Control lighting, climate, and room automation through a single guest interface. Hoteza integrates with leading GRMS platforms to deliver seamless in-room experiences and measurable energy savings.
GRMS
A Guest Room Management System (GRMS) is the core technology behind smart hotel rooms
It connects lighting, HVAC, curtains, occupancy sensors, and guest controls into a unified system. When integrated with Hoteza, GRMS becomes part of the digital guest journey, allowing guests to control their room directly from the TV, tablet, or mobile app without relying on physical switches.
Hotels implementing GRMS integrations benefit from:
- Reduced energy consumption (up to 30%)
- Improved guest satisfaction through personalization
- Automated room behavior based on occupancy and check-in status
Whether you're operating a luxury hotel, boutique property, or planning a new build, GRMS integration enables a more efficient and elevated guest experience.

Quick setup
How GRMS integration with Hoteza works
Hoteza connects to GRMS platforms through a middleware layer using REST API, BACnet, or vendor SDKs. This enables real-time synchronization between room hardware and guest-facing interfaces for a smooth and responsive guest experience.
For certified integrations, no custom development is needed, and setup usually takes 1 to 5 days when the hardware is already installed.
