KNX for Hotels (GRMS)
KNX GRMS - Guest Room Management Without the Lock-In
Most GRMS platforms tie you to one manufacturer’s roadmap, pricing, and product cycle. KNX doesn’t work that way. As the world’s only open protocol for building automation, KNX lets you build a guest room system from the best available hardware, rather than whatever a single vendor happens to be selling this year.
At mySmart, we’re a foundation member of the KNX National Group and one of the few integrators in Australia running true multi-brand KNX GRMS deployments in hotels. That means your thermostat, your lighting actuator, and your door/window sensor don’t need to come from the same badge – they just need to talk KNX, and they always will.
Why KNX Makes Sense for Hotel Guest Rooms
Guest rooms are unforgiving environments – high churn, 24/7 operation, and guests who expect the room to work perfectly every time. KNX earns its place here for a few practical reasons:
- No vendor lock-in. If a manufacturer discontinues a product line, changes pricing, or gets acquired, your building isn’t held hostage. Swap in a certified alternative without ripping out the backbone.
- Proven reliability. KNX has been running hotel back-of-house and guest room systems for over 20 years, on a protocol regulated by the KNX Association and tested to strict international standards.
- Scales with the property. Works the same whether you’re fitting out a 40-room boutique hotel or a 400-room tower, and integrates cleanly with HVAC, lighting, blinds, and energy metering on one network.
- Future-proof by design. New KNX-certified products keep entering the market from an ecosystem of 500+ manufacturers, so the system keeps improving without a forklift upgrade.
Our KNX Brands In The GRMS Space
This is the part most hotel owners don’t realise until they ask: a KNX GRMS isn’t a product, it’s a standard. Once your building runs on the KNX bus, you have access to over 8,000 certified products from more than 500 manufacturers across 190 countries – all interoperable, all tested, all speaking the same language.
In practice, that means we design your guest room system around what actually suits the project – budget, aesthetic, room type, ordering lead times – rather than what one vendor’s catalogue happens to offer. It’s why we can bring you options like ABB, Eelectron, and GVS side by side, and mix components across them where it makes sense.
ABB is one of the most established names in KNX hardware, backed by the scale of a global industrial and building technology manufacturer. For hotel guest rooms, ABB brings robust, well-documented KNX room controllers with a long track record in commercial deployments – a safe, dependable choice where the priority is proven engineering and long-term parts availability.
GVS rounds out the lineup with a strong value-to-features balance, offering KNX-certified guest room thermostats and control components well suited to properties that want full GRMS functionality without over-specifying the hardware. A solid option for scaled rollouts across multiple room types.
Eelectron is a KNX specialist purpose-built for hospitality, and it shows – their guest room thermostats and controllers are designed specifically around the workflows hotels need: occupancy-based HVAC control, minibar and door contact integration, and clean in-room interfaces that guests actually understand. Where ABB brings general-purpose industrial pedigree, Eelectron brings hospitality-first design.

Frequently Asked Questions
Can I mix KNX products in the same hotel?
Yes. Because all KNX-certified, components from different brands communicate on the same bus without special drivers or workarounds. We often mix brands within a single project to match budget or lead-time constraints room by room.
Does a KNX GRMS cost more than a proprietary system?
Not necessarily – and over the life of the building, an open system typically costs less, since you’re not locked into one supplier’s pricing for spares and expansions.
Is KNX suitable for retrofits, or only new builds?
Yes. Because all KNX-certified, components from different brands communicate on the same bus without special drivers or workarounds. We often mix brands within a single project to match budget or lead-time constraints room by room.
