In order to decrease energy expenses and maintain a comfortable indoor climate for the occupants, the building owners required precise temperature data for each room across the 4,500 apartments equipped. A total of 7,800 MClimate HT Sensors LoRaWAN® were installed, enabling real-time tracking of the rooms’ temperature and humidity and collecting historical data. The sensors are integrated into the Kocliko software, allowing the individualization of heating costs and the reduction of energy consumption. To ensure the successful deployment of the solution, the 71 Wattsense Boxes enabled protocol conversion, facilitating communication through BACnet, KNX or Modbus, allowing the 7,800+ MClimate HT Sensors LoRaWAN® to be seamlessly integrated into the Kocliko platform.

The MClimate devices provided humidity data, thus helping track and prevent mold growth across the properties. Furthermore, the LoRaWAN® protocol ensures these smart devices’ operating life is up to 10 years while consuming as little energy as possible, making the solution sustainable over time.

Within the first three heating seasons, we observed a gradual decrease in average temperature across the buildings, moving slowly towards the 19°C recommended average temperature for occupied spaces in French buildings. For instance, in one of the buildings, between 2023/2024 and 2024/2025 heating seasons, the temperature decreased by 1°C. Between 2024/2025 and 2025/2026, it further decreased by 1.5°C. The building owners are aiming to continue this downward trend in order to reach the 19°C target.

The combination of MClimate smart devices integrated into Kocliko software via Wattsense gateways helped the building owners track temperature and the associated heating costs on a room-by-room basis, enabling them to improve energy efficiency and cut CO2 emissions over time.
