Smart G4 Hotel GRMS: The Only System with 11 Series — Wired, Wireless & Retrofit for Every Star Rating

The World's Most Complete Hotel GRMS — And It's Not Even Close

When hotel owners, consultants, and procurement teams evaluate Guest Room Management Systems, they face a frustrating reality: most vendors offer one or two product lines, forcing hotels to compromise on either budget, aesthetics, or capability. You either overpay for a luxury system in a budget property, or you settle for a basic system in a five-star hotel.

Smart G4 solves this completely. With 11 distinct product series spanning wired, wireless, and retrofit technologies, Smart G4 is the only GRMS manufacturer in the world that can equip every room in every hotel — from a 1-star roadside inn to a 7-star palace resort — with the exact right system at the exact right price point.

And the market has noticed. Smart G4 is a multi-award-winning company recognized across four continents, with its flagship Insignia Series alone deployed in over 40,000 hotel rooms globally. That is not a marketing claim — it is a track record built over two decades of hospitality innovation.

---

Why 11 Series? Because No Two Hotels Are the Same

Most GRMS companies offer a single product line and ask hotels to adapt. Smart G4 took the opposite approach: build a series for every real-world scenario.

Here is what that looks like in practice:

Series	Technology	Star Rating	Starting Cost
Easy GRMS	Wired	1–2 star, budget	From $75/room
Simple Slave	Wired economy	Budget, hostels	From $75/room
Standard GRMS	Wired	3–4 star	From $98/room
Insignia	Wired premium	4–5 star	Mid-range
Sophi Retrofit	Powerline/Zigbee/BLE/RF	Existing hotels	Retrofit pricing
Professional GRMS	Wired advanced	5-star boutique	Custom quote
G-Platter	Wired high-end	5–6 star	Premium
Mil Luxury	Wired luxury	6–7 star	Premium
Q-Metalica Extreme	Wired ultra-luxury	6–7 star	Premium
BioHotel	Biometric + access	All star ratings	Add-on module
HornetX HX	100% Wireless	Retrofit, all ratings	From $98/room

No other company in the hospitality automation industry offers this breadth. Not Siemens. Not Honeywell. Not INTEREL. Not ABB. Only Smart G4.

HornetX HX Wireless Series: Full GRMS Without a Single New Wire

The HornetX HX Series is a revolution for existing hotels. It delivers 100% full GRMS functionality without any new wiring — using a proprietary wireless mesh protocol that penetrates walls, floors, and ceilings.

This is not a stripped-down wireless system. HornetX HX includes:

• HornetX main panel — the wireless hub for the entire room

Sophi Retrofit Series: Powerline, Zigbee, BLE & RF — Four Protocols, One System

The Sophi Retrofit Series takes a different approach to existing hotel upgrades. Rather than wireless mesh, Sophi uses the existing electrical wiring as a communication backbone (Powerline technology), supplemented by Zigbee, BLE, and RF protocols.

• 3-button and 4-button panels — drop-in replacements for existing switches
• 6-button panel — full scene control in a standard switch footprint
• Wireless thermostat — Zigbee/BLE connected
• Multi-combination illustrated panels — custom configurations per room type

Sophi is ideal for heritage buildings, listed properties, and hotels where wireless signal penetration is a concern.

---

BioHotel Series: Biometric Access Across the Entire Property

The BioHotel Series extends Smart G4's intelligence beyond the guest room to every access point in the hotel. This is where Smart G4 truly separates itself from every competitor:

Elevator Floor Control Access

Smart G4 integrates directly with elevator control systems to enforce floor-by-floor access control:

• Guests can only access their assigned floor — no unauthorized movement between floors
• VIP floors, executive levels, and staff-only zones enforced automatically
• PMS integration assigns access rights at check-in — no manual configuration
• Real-time elevator status, call logs, and fault alerts on the BMS dashboard

No other GRMS vendor offers this level of elevator integration as a standard product.

Parking Space Management

Smart G4's parking management is fully integrated with the hotel PMS:

• Smart Pay-to-Park — guest vehicle registered at check-in, charges added to room bill automatically
• Real-time bay occupancy sensors — visible on lobby display and hotel app
• ANPR (Automatic Number Plate Recognition) — cameras control entry/exit barriers for registered guests and staff
• EV charging station control — billing integration for electric vehicles

Gym & Pool Access Control

Smart G4 manages access to all hotel amenity areas through the same unified platform:

• Gym access — controlled by guest card, time schedule, or membership level
• Pool access — restricted by booking, guest category, or time of day
• Spa and wellness areas — VIP access tiers enforced automatically
• Housekeeping access — staff access controlled and logged for security

The BioHotel Series also includes full PWD (Persons with Disabilities) accessibility compliance — automatic door openers, accessible elevator controls, and emergency call integration.

Wireless Curtain Motors, Thermostats & Magnetic Contacts: The Energy Saving Trinity

One of Smart G4's most distinctive capabilities is its ecosystem of wireless comfort and energy-saving devices that work seamlessly with every series:

Wireless Curtain Motors

• Battery-powered wireless curtain motor — installs in minutes, no electrician required
• Solar-powered wireless curtain motor — self-sustaining, zero running cost
• Integrates with room scenes: "Good Morning" opens curtains automatically
• Closes curtains when room is vacant to reduce solar heat gain and HVAC load
• Works with wired and wireless GRMS series alike

Wireless Thermostats

Smart G4's wireless thermostats communicate via Zigbee, BLE, or the HX proprietary protocol:

• Precision ±0.5°C temperature control
• Setback mode when room is vacant — saves up to 40% on HVAC energy
• Integrates with the hotel BMS for central monitoring and override
• Available in designs matching every series from Sophi to Mil Luxury

Door & Window Magnetic Contacts

This is one of Smart G4's most impactful energy-saving innovations:

• Wireless magnetic contact on balcony/terrace door detects when it is opened
• HVAC automatically suspends when the door is open — no energy wasted cooling the outdoors
• Alert sent to BMS if door remains open for more than a configurable time period
• Works in both wired and wireless GRMS configurations
• Payback period measured in weeks, not years

In a 200-room hotel, this single feature alone can save tens of thousands of dollars annually in HVAC energy costs.

PMS Integration: API, DDL, XML & Direct Modules

Smart G4 integrates with every major Property Management System on the market through multiple integration pathways — giving hotels the flexibility to connect regardless of their existing infrastructure:

REST API Integration

Smart G4's open REST API allows real-time bidirectional communication with PMS platforms:

• Check-in/check-out events trigger room automation scenes automatically
• Guest preferences (temperature, lighting, language) loaded from PMS profile
• Room status (occupied, vacant, cleaning, maintenance) synchronized in real time
• Energy consumption data pushed to PMS for billing and reporting

DDL (Direct Database Link) Integration

For PMS platforms that support direct database connectivity:

• Smart G4 reads and writes directly to the PMS database
• No middleware required — lowest latency, highest reliability
• Supports Oracle, SQL Server, MySQL, and PostgreSQL backends
• Ideal for large hotel groups with custom PMS deployments

XML Integration

Industry-standard XML messaging for PMS platforms including:

• Opera (Oracle Hospitality) — the world's most widely deployed hotel PMS
• Protel — popular in European hotel groups
• Fidelio — legacy and modern versions
• Micros — F&B and front-of-house integration
• IDS Next — Asia-Pacific hotel groups
• Hoist Group — Scandinavian and European properties

Direct Integration Modules

Smart G4 also offers hardware-level direct integration modules for PMS systems that do not support API or XML:

• RS-232 and RS-485 serial communication modules
• Relay-based trigger interfaces for legacy PMS systems
• OSDP and Wiegand interfaces for access control integration
• KNX bridge for properties already running KNX infrastructure

This multi-pathway approach means Smart G4 can integrate with any PMS, anywhere in the world — a claim that no single-protocol competitor can make.

Energy Saving: The Numbers That Matter

Smart G4's energy management is not a feature — it is a core engineering philosophy embedded in every series:

Guaranteed 80% reduction in energy wastage through:

• Smart Occupancy Technology (SOT) — multi-sensor presence detection combining door contacts, motion, heartbeat/breathing sensors, and utility usage analysis
• Room Utilities Usage Analysis (RUA) — per-room energy metering with hourly, daily, and per-stay reporting
• Water Wastage and Budgeting Technology — water budget per guest, automatic shutoff in vacant rooms
• HVAC setback — automatic temperature adjustment when room is vacant or guest is sleeping
• Lighting scene management — daylight harvesting, occupancy-based dimming, and scheduled scenes
• Balcony door HVAC suspension — via wireless magnetic contacts
• Curtain automation — solar heat gain management through automated blind control

The Health Conservation System (HCS) — patented by Smart G4 — goes further still: when a guest activates sleep mode, the system gradually raises room temperature by 1°C every 1.5 hours, matching the human body's natural temperature drop during sleep. Over an 8-hour sleep cycle, the room moves from 19°C to 24°C automatically — improving sleep quality while reducing overnight HVAC load.

The Complete Hotel Ecosystem: Beyond the Guest Room

What truly makes Smart G4 unique is that the GRMS is just the beginning. The same platform extends to every system in the hotel:

Building Management System (BMS) Integration

Smart G4's BMS layer monitors and controls:

• HVAC plant rooms — chillers, AHUs, FCUs, and VRF systems
• Electrical distribution — main switchboards, sub-meters, and power quality monitoring
• Lighting control — common areas, corridors, lobbies, and facades
• Fire alarm integration — automatic room evacuation scenes
• Security systems — CCTV, access control, and intrusion detection

Hotel Advertisement & Digital Signage

Smart G4 integrates with in-room and public-area digital signage:

• Welcome messages personalized to guest name and language
• Promotional content managed centrally from the BMS
• Emergency notifications pushed to all displays simultaneously

KNX Bridge Integration

For properties already running KNX infrastructure, Smart G4's KNX Bridge provides seamless bidirectional integration — allowing Smart G4 GRMS panels to control KNX devices and vice versa. This protects existing KNX investments while adding Smart G4's hospitality-specific capabilities.

---
