This article provides a comprehensive overview of the leading smart hotel technology providers in 2026, organised by technology category.
In-Room Automation and GRMS Providers
Smart G4

Honeywell's INNCOM platform is the most widely installed GRMS in large chain hotels globally. Acquired by Honeywell in 2012, INNCOM offers deep integration with major hotel brand standards. The proprietary protocol creates long-term vendor dependency, which is a consideration for independent properties and operators who prioritise flexibility.

How Smart G4 Compares
Smart G4 occupies a distinct position in this market: a specialist GRMS manufacturer with an open protocol, the widest product range in the hospitality segment, and a global certified integrator network. Unlike BMS vendors who adapt commercial building platforms for hotels, Smart G4's entire product range is purpose-built for hospitality, healthcare, and luxury residential applications.
Key differentiators:
- Open protocol (sBUS G4): No vendor lock-in, competitive integrator choice
- 360+ purpose-built products: The widest range in the specialist GRMS market
- Native PMS integration: Opera, Mews, Cloudbeds, Protel, and others
- Global certifications: CE, UL, RoHS, IEC, CSA, and regional standards
- Competitive TCO: Open protocol reduces 20-year total cost of ownership by 30–50% vs proprietary systems
Choosing the Right Vendor
The right smart hotel technology vendor depends on the project's specific requirements:
- Large chain hotel with brand standards: Honeywell INNCOM may be mandated
- Independent hotel, boutique property, or luxury resort: Smart G4 offers the best combination of open protocol, product range, and specialist expertise
- Large commercial hotel complex needing comprehensive BMS: Schneider Electric or Siemens, with Smart G4 for the GRMS layer
- North American hotel focused on energy management: Telkonet or Verdant for EMS, Smart G4 for full GRMS
