Background

Lječilište Veli Lošinj, a renowned health resort on the Croatian island of Lošinj, launched a wide-ranging energy management and digitalization project aimed at improving operational efficiency, guest comfort, and environmental performance. The initiative, aligned with the ISO 50001 standard and funded through the Croatian National Recovery and Resilience Plan, included multiple layers: energy and water consumption monitoring through an AMR system, air quality monitoring, intelligent HVAC control, and flood detection.

The solution was deployed across seven buildings within the resort complex, each with varying functions and technical conditions. Within this broader framework, Milesight's LoRaWAN®-based IoT solutions played a key role in enabling real-time environmental monitoring and automation—enhancing control, visibility, and responsiveness in areas critical to health and wellness.

Solution

Smart Monitoring for Comfort and Operations

AM103 and AM308 IAQ sensors, EM300-TH temperature & humidity sensors, and LoRaWAN®-enabled water and electricity meters collect environmental and utility data throughout the resort. The data is transmitted via the UG67 gateway to the AMR Emasys Monitoring App, supporting daily comfort management and providing actionable insights for operational optimization.

Real-Time Leak Detection

The WS303 Mini Leak Detection Sensor monitors water leaks and transmits real-time
alerts via the UG67 gateway to the Beaver IoT platform. This enables immediate
response and predictive maintenance to minimize downtime and prevent damage.

Smart HVAC Control Based on Window Status

The WS301 Magnetic Contact Switch detects whether windows in guest rooms are open or closed. This information is sent via the UG67 LoRaWAN® gateway to the Beaver IoT platform (hosted on the Emasys APP server). Once received, the platform analyzes the data then sends commands to the UC300 Controller and adjusts the HVAC system accordingly. This automated setup ensures real-time HVAC control based on actual room conditions, reducing energy waste and enhancing both system efficiency and guest comfort.
