Built on the globally recognised KNX standard, Zennio enables hotel owners, operators, and consultants to enhance guest comfort while achieving proven energy savings of 50–60%.
From guest rooms to bars, restaurants, and shared spaces, Zennio provides seamless control, deep PMS and guest app integration, and intelligent back-of-house tools for maintenance and housekeeping. Centralised via ZBMS and compatible with leading access control manufacturers including SALTO, ASSA ABLOY, and DORMAKABA, Zennio is deployed in tens of thousands of guest rooms worldwide and is equally suited to new-build developments and live-hotel refurbishments, delivering resilience, flexibility, and long-term value without proprietary lock-in.
Zennio Hospitality Solutions: Intelligent Control, Exceptional Experiences, Measurable Energy Savings
As the hospitality sector enters 2026, operators, owners, and consultants face a familiar but increasingly complex challenge: how to enhance the guest experience while simultaneously reducing operational costs, improving sustainability performance, and future-proofing investments against rapid technological change. At Zennio, we believe these objectives should never be in conflict. When approached intelligently, they reinforce one another.
Zennio delivers an open, fully integrated hospitality control platform that is specified by consultants, trusted by integrators, and adopted by hotel owners and operators across both new-build and refurbishment projects. Built on the globally recognised KNX, Zennio protects long-term asset value by avoiding proprietary lock-in while remaining flexible enough to evolve alongside future hotel requirements.
A Complete GRMS for Modern Hotels
Zennio’s Guest Room Management System (GRMS) coordinates lighting, HVAC, shading, presence detection, DND/MUR status, and access control inputs into a single intelligent environment. Each room operates as a distributed, autonomous system, responding in real time to guest behaviour, booking status, and operational workflows.
For guests, the experience is intuitive and consistent: smooth lighting transitions, responsive temperature control, and interfaces that feel natural rather than technical. For operators, rooms become dynamic assets that automatically adapt to occupancy and usage patterns, reducing energy waste while maintaining comfort at all times.
By distributing intelligence at room level rather than relying on a single central server, Zennio improves system resilience, reduces network dependency, and enhances cybersecurity, an increasingly important consideration for modern hospitality developments.
Public Areas, Bars, and Restaurants: One Platform, One Experience
Guest experience extends far beyond the bedroom. Public areas, bars, restaurants, lounges, and meeting spaces are where brand identity is expressed most clearly, and where intelligent control delivers immediate impact.
Zennio enables lighting and HVAC control across all public areas using the same KNX-based infrastructure as guest rooms. Lighting scenes evolve throughout the day to support different operational modes, from breakfast and meetings to evening dining and late-night ambience. HVAC strategies adapt dynamically to occupancy and external conditions, ensuring comfort without unnecessary energy consumption.
The result is a cohesive guest journey, simplified system architecture, and consistent operational logic across the entire hotel.
Centralised Intelligence with ZBMS
For medium and large hospitality projects, centralised visibility is essential. Zennio delivers this through ZBMS, providing a unified overview of all guest rooms and public areas from a single platform.
Engineering and facilities teams can monitor room status, HVAC performance, alarms, and energy usage in real time, allowing issues to be identified proactively rather than reactively. For hotel groups and asset managers, ZBMS also supports benchmarking and performance analysis across multiple properties, enabling data-driven operational and investment decisions.
PMS, Guest App, and Back-of-House Integration
Operational efficiency is unlocked through integration. Zennio interfaces seamlessly with leading Property Management Systems (PMS), guest engagement platforms, and back-of-house applications.
Rooms automatically transition between occupied, vacant, and standby modes based on PMS status, ensuring energy is never wasted conditioning empty spaces. Guest apps enable personalised control of lighting and temperature, while back-of-house tools provide maintenance and housekeeping teams with accurate, real-time information, reducing unnecessary room entries and improving coordination between departments.
Integrated Access Control for a Seamless Journey
Zennio integrates with leading hospitality access control manufacturers, including SALTO, ASSA ABLOY and DORMAKABA.
Access events become active inputs into the GRMS logic, enabling secure, automated responses that enhance both guest experience and energy performance. Comfort, security, and efficiency operate as a single coordinated system rather than isolated technologies.
Sustainability That Delivers Real ROI
Zennio hospitality solutions routinely deliver 50–60% reductions in guest-room energy consumption, primarily through intelligent HVAC control, occupancy-based strategies, and centralised oversight.
Crucially, these savings are achieved without compromising guest comfort. In many cases, comfort is enhanced, supporting stronger guest satisfaction scores, improved ESG performance, and faster return on investment for owners and operators.
Built on Open Standards, Ready for the Future
Hotels are long-term assets, and technology decisions must endure beyond a single refurbishment cycle. By embracing KNX, Zennio ensures compatibility with multi-vendor ecosystems, adaptability to future requirements, and long-term supportability.
Zennio solutions are deployed in tens of thousands of guest rooms worldwide, across independent hotels and international brands, and are equally suited to new-build developments and phased refurbishments in live operational environments.
Setting the Standard for Hospitality Control in 2026 and Beyond
As hospitality professionals plan for 2026 and beyond, the question is no longer whether intelligent control is required, but how openly, resiliently, and sustainably it is delivered.
For those seeking a future-proof alternative to proprietary GRMS platforms, Zennio represents a proven, open, and intelligent approach to hospitality control, enhancing guest experience, empowering hotel teams, and delivering measurable energy and operational benefits over the long term
