Background

A 170-room Novotel hotel in France, spanning approximately 7,300 m², faced the challenge of modernizing aging building infrastructure in a fully operational environment. With legacy controllers in guest rooms, electric convectors in common areas, and multiple technical systems in place, the hotel required a modern Building Management System (BMS) to improve comfort, reduce energy consumption, and enable centralized control — all without disrupting daily operations or requiring costly renovations.

Challenges

Integration with Existing Infrastructure

Legacy controllers and third-party sensors made deployment more complex, limiting flexibility and increasing costs.

Non-Disruptive Deployment

The upgrade had to be completed quickly and discreetly, without disrupting daily operations or affecting guest experience.

Fragmented Building Systems

Different systems operated independently, limiting visibility and preventing centralized control.

Complex and Device-Heavy Deployment

Multiple devices were required per room for control, sensing, and communication, making deployment time-consuming and difficult to manage.

Solution

To address these challenges, a LoRaWAN®-based solution was deployed, combining Milesight IoT devices with the SCorp-io BMS platform. The platform enables centralized monitoring, control, and integration with hotel systems.

Guest Rooms — One Device Replacing an Entire Architecture

To upgrade the guest room HVAC systems without complex rewiring, the solution reuses existing wiring and replaces the original Siemens wall controllers with Milesight WT303 Smart Fan Coil Thermostats. By integrating temperature sensing, fan coil control, and wireless communication into a single device, it significantly reduces hardware requirements and deployment complexity.

To further minimize installation impact, no additional occupancy sensors were installed. Through its BMS platform, SCorp-io integrates PMS data with HVAC control, enabling contextual and automated management—without adding extra IoT devices in guest rooms.

Common Areas — One Thermostat Controlling Multiple Convectors

In shared spaces such as lobbies, restaurants, and meeting rooms, Milesight WT401 Wireless Smart Thermostats were deployed to control 3 to 5 electric convectors within the same zone, simplifying system architecture while reducing the number of required devices.

SCorp-io's BMS platform enables automated temperature adjustments based on usage scenarios, such as meeting schedules or operating hours, improving both energy efficiency and operational convenience.

Technical Systems — One Platform Unifying All Building Systems

Milesight TS302 LoRaWAN® Temperature Sensors were deployed to monitor domestic hot water supply and return temperatures, a critical parameter in hotel operations. In addition, all building systems—including HVAC, heat pumps, air handling units, and sub-metering—are integrated into the SCorp-io BMS platform, where it enables centralized monitoring, control, and system integration.

Supported by Milesight UG65 Semi-Industrial LoRaWAN® Gateways, the solution ensures reliable, long-range connectivity across the entire hotel, enabling seamless data transmission between field devices and the SCorp-io platform for centralized management.

Results

Minimal Renovation with Reduced Operational Disruption

By reusing existing wiring and infrastructure, the project avoided heavy construction work. With a single device per room and no additional occupancy sensors required, the deployment was completed faster and with minimal disruption to daily operations.

One Device Replacing an Entire Architecture

The use of integrated LoRaWAN® devices eliminates the need for multiple devices per room, reducing installation complexity while simplifying long-term operation and maintenance.

Unified Building Management System

By integrating PMS data with HVAC control, the system enables automated and centralized management across guest rooms, common areas, and technical systems, improving operational visibility and efficiency.
