Milesight WT101-868M is a smart LoRaWAN radiator thermostat designed for precise temperature control in individual rooms. The built-in NTC sensor measures temperature within a range of −20…+60°C, while the stepper motor automatically controls the radiator valve opening level.
The WT101 supports automatic temperature control, direct valve opening control, up to 16 heating plans, open-window detection, freeze protection, and Child Lock. Two replaceable Li-FeS₂ AA batteries provide approximately 8 years of operation at SF7/EU868 under the manufacturer's test conditions.

WT101 — Precise Control of Every Radiator
Milesight WT101 is a smart thermostatic radiator valve designed for automatic and remote temperature control in rooms equipped with water-based radiators.
The built-in temperature sensor, stepper motor, and LoRaWAN communication enable dynamic control of water flow through the radiator and the creation of independent heating zones in individual rooms throughout the building.
Individual Temperature Control and Lower Energy Consumption
Automatic Control
The WT101 automatically adjusts the valve position to keep the temperature as close as possible to the configured setpoint.
16 heating plans
Schedules make it possible to automatically change the temperature depending on the time of day and how the room is used.
Approximately 8 Years of Operation
Two replaceable Li-FeS₂ AA batteries provide many years of operation without the need to run power cables.
Where Can the WT101 Be Used?
Automatic Temperature Control or Direct Valve Opening
Automatic Temperature Control
The device automatically adjusts the valve position based on the temperature setpoint and the current room measurement.
Valve Opening Control
The valve opening level can also be controlled directly within a range of 0 to 100%.
Effective Stroke
The Effective Stroke function makes it possible to limit the maximum valve opening and better adapt thermostat operation to a specific installation.
Built-in NTC Sensor
Up to 16 Plans Adapted to Building Usage
The WT101 allows one calendar period and up to 16 individual heating plans to be configured.
This makes it possible to automatically lower the temperature at night or when users are absent and restore a comfortable setpoint before the room is occupied again.
Automatic Open-Window Detection
The Open-Window Detection function analyses the rate of temperature decrease in the room.
When a characteristic rapid temperature drop is detected, the WT101 can interrupt control and adjust the valve position accordingly, reducing unnecessary heating while the room is being ventilated.
Automatic Freeze Protection
Freeze Protection enables an automatic response when the temperature falls below the configured threshold.
The thermostat can open the valve accordingly, helping to reduce the risk of the installation freezing during prolonged absence or very low temperatures.
Child Lock, Tamper Alarm and Mechanical Protection
Child Lock
The control knob lock prevents users from changing the temperature setpoint themselves while the function is active.
Tamper Alarm
The built-in mechanism can indicate an attempt to tamper with or remove the device without authorisation.
Anti-theft
An optional metal security collar can make it more difficult to remove the thermostat from the valve.
Temperature Can Come from a Different Measurement Point
The temperature measured directly at the radiator may differ from the temperature in the central part of the room.
The WT101 supports External Sensor Mode, allowing it to use a temperature value supplied from an external source via the LoRaWAN system.
M30 × 1,5 mm and Optional Adapters
Valves other than the standard M30 × 1,5 mm require a suitable adapter. Milesight offers the TRA3015 adapter set, among others.
Control Knob and White LED Display
LED
The built-in white LED display presents the information needed during local device operation.
Control Knob
The user can locally change the temperature value or valve opening level depending on the active mode.
NFC
Device parameters can be quickly configured using the Milesight ToolBox app.
Up to Approximately 8 Years of Wireless Operation
The WT101 is powered by two replaceable 1,5 V Li-FeS₂ AA lithium batteries with a total capacity of 3000 mAh.
According to the current Milesight specification, battery life is approximately 8 years at SF7/EU868 and approximately 5 years at SF10/EU868 under the manufacturer's test conditions.
Communication, Power Supply and Design
* The manufacturer specifies approximately 8 years of operation at SF7 / EU868 and approximately 5 years at SF10 / EU868. Test conditions: 10-minute reporting interval, one adjustment during a 5-month heating season, and a temperature of 25°C. Actual battery life depends on configuration, radio conditions, temperature, and valve operating frequency.
WT101 in a Smart Heating System
Temperature, valve position, and setpoints can be transmitted via LoRaWAN to a central system, enabling remote heating management across multiple rooms.
