Milesight WT102-868M is a self-powered smart LoRaWAN radiator thermostat that uses radiator heat energy to power its electronics and valve actuator. Thanks to energy harvesting technology, the device does not require periodic battery replacement or a permanent wired power source.
The WT102 measures temperature within a range of −20…+60°C, automatically controls the valve opening and allows the target temperature to be set within a range of 5…35°C. It supports up to 16 heating plans, open-window detection, freeze protection, storage for 1000 records, LoRaWAN Class B, NFC configuration, and an optional external NTC sensor connected via USB-C.

WT102 — Smart Heating Without Battery Replacement
Milesight WT102 is a smart LoRaWAN radiator thermostat designed for automatic room temperature control without the need for periodic battery replacement.
The device uses the temperature difference between the radiator and its surroundings to generate electrical energy. This significantly reduces maintenance requirements, particularly in large installations with dozens or hundreds of radiators.
Precise Control Without Battery Replacement Costs
Energy Harvesting
The WT102 uses energy generated by the temperature difference between the heating installation and its surroundings and does not require standard batteries.
5–35°C Control Range
Automatic valve control makes it possible to maintain the desired temperature independently in each room.
LoRaWAN Class B
Class B support enables faster reception of remote commands than in typical battery-powered devices operating only in Class A mode.
Where Can the WT102 Be Used?
Energy Harvested Directly from the Heating Installation
The WT102 uses the thermoelectric effect. The difference between ambient temperature and radiator temperature is converted into electrical energy and used to power the device.
The manufacturer indicates that when the water temperature exceeds approximately 45°C, the device can be effectively powered by energy harvested from the temperature difference.
USB-C for Start-Up or an Extended Heating Break
If the stored energy level is insufficient, the WT102 can be powered or charged via the 5 V USB Type-C port.
According to the manufacturer, approximately 30 minutes of charging provides around 20% energy level, while a full charge takes approximately 6 hours and 30 minutes.
Automatic Temperature and Valve Opening Control
Automatic Temperature Control
The thermostat automatically adjusts the valve opening to the desired room temperature.
Valve Opening Control
The valve opening level can also be controlled directly within a range of 0 to 100%.
Integrated Control
Integrated mode combines automatic temperature control with the ability to transmit valve opening commands.
Built-in NTC Sensor
More Accurate Measurement Away from the Radiator
Temperature measured directly at the radiator may differ from the temperature experienced in the central part of the room.
The WT102 can therefore work with an optional external NTC sensor connected to the USB-C port or with the wireless WT401 thermostat, which can provide temperature data from a more representative location in the room.
Up to 16 Individual Heating Plans
The WT102 supports one configurable calendar period and up to 16 heating plans.
This makes it possible to automatically lower or raise the temperature depending on the day, time, and actual use of the room.
Automatic Response to Changing Conditions
Open-Window Detection
A sudden temperature drop can be recognised as an open window. The thermostat can then close the valve and reduce unnecessary heating.
Freeze Protection
If the temperature becomes too low, the valve can be opened automatically, helping to protect the installation against freezing.
Effective Stroke
The Effective Stroke function makes it possible to adapt the actual actuator operating range to the valve and the way the installation operates.
Child Lock and Removal Protection
Child Lock
The local control lock prevents unauthorised temperature changes by users.
Metal Design
The aluminium-based enclosure increases the device's resistance to mechanical damage in public spaces.
Anti-Theft Protection
An optional mechanical security collar can make it more difficult to remove the thermostat from the valve without authorisation.
1000 Records and Retransmission
1000 Records
The built-in memory allows up to 1000 historical records to be stored locally.
Retransmission
Data stored during temporary communication loss can be transmitted after the LoRaWAN connection is restored.
Data Retrievability
Historical information can be retrieved again from the device memory.
M30 × 1,5 mm and a Wide Selection of Adapters
Communication, Power Supply and Design
WT102 in a Smart Heating System
Valve status, temperature, setpoints, and stored energy level can be transmitted via LoRaWAN to a central heating management system.
