Description

The Milesight WT102 is a groundbreaking Self-Powered LoRaWAN Radiator Thermostat designed for sustainable, large-scale building automation. By utilizing advanced thermal energy harvesting, the WT102 converts the temperature difference between the radiator and the ambient air into electrical power, effectively eliminating the cost and labor associated with battery maintenance. It features a high-precision NTC sensor for local detection, with the option to link to the WT401 wireless thermostat for enhanced room-wide accuracy. With support for Milesight D2D, the WT102 enables instant local synchronization with window sensors to pause heating when a leak of thermal energy is detected, ensuring maximum efficiency without gateway intervention.

Maintenance-Free Thermal Control

Zero-Battery Operation Harvests heat energy directly from the radiator valve. A USB Type-C port is also provided for initial charging or auxiliary power if needed.
Milesight D2D Controller & Agent Operates as both a D2D agent for external commands and a controller for local scenes, ensuring heating response times under 1 second.

Professional Heating Scenarios

• Public Buildings: Deploy maintenance-free heating in schools and hospitals where battery swaps are impractical.
• Smart Campus: Centrally manage thousands of radiators with 16 daily heating plans to align with classroom schedules.
• Historic Retrofitting: Add wireless smart control to legacy radiator systems without the need for any wiring or power infra.
