Why Hotels Choose INTEREL’s Guest Room Management System

For countless reasons, but if we had to pick just one, we would say: 

Because every integration is built with a deep understanding of hospitality operations and guest experience. This results in bidirectional integrations that exchange data points and events that make all the difference.

Faster Guest Service from Smarter Room Controls

  • Our GRMS integrates with your Workflow Systems, instantly updating the status of the rooms.

    When a guest taps on Privacy or Service, this information is immediately shared with your housekeeping staff, allowing them, for example, to prioritize empty rooms for cleaning.

    Optimize workflow, save time, and provide amazing service for your guests.

Door Lock Integrations and Virtual Infrastructure

  • We integrate with leading door lock brands to enhance security and convenience.

    With a single click, you can extend guest stays, change rooms, or deactivate lost staff cards.

    Receive proactive low-battery alerts and real-time audit logs.

    Leverage door events combined with our energy-saving algorithms, eliminating the need for door contacts. Embrace digital key solutions, enabling guests to access their rooms via smartphone.

IPTV Integration

  • Nowadays, large-screen TVs in hotel rooms consume more energy than the lights.

    Our GRMS uses occupancy detection to automatically turn off the TV in empty rooms, reducing energy consumption and promoting sustainability.

We Blend in Better Than Anyone Else.

our interface portfolio offers multiple design approaches to match every hospitality concept.
