## New Milesight WT102 Device: Self-Powered LoRaWAN Smart Thermostatic Valve

### Maintenance-free, durable, and designed to drastically reduce energy consumption

#### Smart Heat Management

Tired of the costs associated with replacing batteries in thermostatic valves, 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, ensuring long-term performance with zero maintenance. Thanks to this **thermal energy recovery** technology, the device operates autonomously, offering a completely **battery-free** user experience. By monitoring ambient temperature in real-time, the WT102 precisely and dynamically adjusts the valve opening. This ensures an extremely responsive system, capable of perfectly balancing **comfort,** **energy saving** 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 heating control 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 predefined period.
- Instant open window detection, so if the temperature drops sharply, the valve avoids opening completely, preventing unnecessary energy waste.
- Automatic anti-freeze protection: when the internal temperature drops towards 3°C, the valve automatically opens to keep the environment above the safety threshold, preventing pipe breakage and structural damage.
- **LoRaWAN Class B Technology**

- WT102 uses the LoRaWAN Class B protocol which ensures a response speed to remote commands 20 times faster than standard Class A. This allows immediate management via IoT platforms, ideal for rapid updates and real-time monitoring on a large scale.
- **Quick Installation and Remote Management**

- Remote batch management via FUOTA, which allows updating the firmware of the entire set of installed devices remotely, without having to physically intervene on each radiator.
- NFC "One-Touch" configuration that allows you to configure your devices in seconds via smartphone.
- **Smart Pairing**

- It pairs perfectly with the wireless thermostat [**WT401**](https://shop.marcomweb.it/it/shop-online/wt401-termostato-intelligente-wireless-lorawan-dettagli.html), allowing centralized and simultaneous management of multiple devices in the same environment and eliminating thermal discrepancies or access difficulties typical of corner installations. Furthermore, 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.

#### Robust and Intuitive Design

- **Maximum Robustness in Metal**

- Made with a robust metal casing to resist impacts and collisions, ideal for extending the device's lifespan in places like 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 childproof tamper lock and an anti-theft physical design, ensuring settings remain protected and the device stays securely in place.
