New Milesight WT102 Device: Self-Powered Smart Radiator Thermostat LoRaWAN

Maintenance-free, Durable and engineered to drastically reduce energy consumption

Smart Heat Control

Tired of the costs associated with replacing thermostat batteries, especially in buildings with many rooms or hard-to-reach locations?                                                                  The WT102 model is designed for smart and automated heating control: it recovers energy from the temperature difference between the hot water in the radiator and the surrounding environment, guaranteeing long-term performance with zero maintenance. Thanks to this thermal energy recovery technology, the device operates autonomously, offering a totally battery-free user experience. By monitoring the ambient temperature in real time, the WT102 regulates the valve opening with dynamic precision. This ensures an extremely responsive system, capable of perfectly balancing comfort, energy savings, and significantly reduced maintenance costs.

Unlike traditional systems, where the lack of control over valves leads to overheating and continuous thermal fluctuations, the WT102 offers greater control over heating based on real-time temperature variations, also limiting the maximum valve opening to control heat dissipation and prevent overheating.

              

Advanced Programming and Connectivity

  • Zero-waste strategies
    • WT102 allows local programming of up to 16 heating schedules within a preset period.
    • Instant open window detection: therefore, if the temperature drops sharply, the valve avoids opening completely, preventing unnecessary energy waste.
    • Automatic anti-frost protection: when the indoor temperature drops towards 3°C, the valve opens automatically to keep the environment above the safety threshold, preventing pipe bursts and structural damage.
  • LoRaWAN Class B Technology
    • WT102 uses the LoRaWAN Class B protocol, which guarantees a response speed to remote commands 20 times faster than the standard Class A. This allows for immediate management via IoT platforms, ideal for rapid updates and large-scale real-time monitoring.
  • Rapid installation and remote management
    • Remote batch management via FUOTA, which allows updating the firmware of the entire fleet remotely, without having to physically intervene on each radiator.
    • NFC "One-Touch" configuration, which allows you to configure your devices in a few seconds via smartphone.
  • Smart Pairing
    • It pairs perfectly with the WT401 wireless thermostat, allowing centralized and simultaneous management of multiple devices in the same room and eliminating thermal discrepancies or access difficulties typical of corner installations. Additionally, the system synchronizes perfectly with the entire LoRaWAN® ecosystem (including gateways, PIR sensors, door sensors, and temperature and humidity sensors) to create dynamic and continuous environment management.

Intuitive and Robust Design

  • Maximum Metal Robustness
    • Made with a robust metal casing to withstand impacts and collisions, ideal for extending the device's lifespan in places such as schools and public spaces.
  • Intuitive Use and Total Protection
    • The minimalist interface ensures simple and immediate interaction, making device control accessible to everyone.
    • The device includes a tamper-proof child lock and a physical anti-theft design, ensuring that settings remain protected and the device stays securely in place.
