The TP-Link Kasa Smart KE100 is a Thermostatic Radiator Valve designed to control the radiator valve. The device communicates wirelessly with a Kasa Smart Hub (required for operation, sold separately or in a kit with the Hub). The user can control the valve and temperature using the Kasa Smart mobile application (available for Android / iOS) from anywhere and at any time. The thermostat is compatible with voice assistants such as Google Assistant and Alexa, allowing control via voice commands. The mobile application allows for creating personalized thermostat schedules and introducing simple automation rules. The set includes mounting adapters, ensuring compatibility with most standard radiator valves on the market.
Precise Temperature Control
The offered product allows precise control of the room temperature. From the moment of activation, the thermostat controls the radiator valve to maintain the indicated temperature. Its operation is highly precise, meeting the expectations of even the most demanding users.

Comfort and Energy Savings
The thermostatic valve will ensure comfort in your home by maintaining an optimal temperature.
Additionally, you can save up to 30%1 of energy consumed, lowering maintenance costs.

Measurement Accuracy up to 0.1?
A built-in high-precision sensor detects even the smallest temperature fluctuations.
Fast Response at 2 Seconds
The device quickly responds to temperature changes and remote commands. Its intelligent algorithm guarantees comfort and prevents energy waste.


Thrust Force up to 10kg
The thermostatic valve has a powerful motor that will open and close most radiator valves without the slightest difficulty. Smoothly control your radiators to achieve the perfect temperature in seconds.
Automatic Room Heating
Set a heating schedule for each room based on your daily routine, saving on energy bills.


Warmth Upon Return
Thanks to the Geofencing function, your home will heat up when you are returning to it. Set the desired range from 100 meters to 2 kilometers, and you can always enter a cozy home.
Control from Anywhere
Manage the radiators in your home using your phone. No more guessing whether you left the radiator on in an empty room.


Convenient Voice Control
Ask Alexa or Google Assistant to change the temperature in your home. Forget about having to get up from the couch and manually adjusting the radiators.
Heating Tailored to Individual Needs
With the ability to customize each room and synchronize controlled devices, the KE100 provides versatility and ease of use.

Comfort in Every Room
Lower Heating Costs
Set the perfect temperature individually for each room and define the heating area of your home. Wasting energy on empty rooms will become a thing of the past.
Group Device Control
Comfort at Your Fingertips
Add several smart radiator valves to a group and control them with one click. This is an ideal solution for large rooms with more than 1 radiator, ensuring a stable temperature in the home.

Improved Functionality with Tapo Sensors
Connect smart sensors to the Kasa Smart Hub in the Kasa Smart app to enhance smart heating capabilities. No additional apps or hubs are required.

External Temperature Sensor
Support for external temperature sensors such as Tapo T310 and Tapo T315 allows for precise temperature control in any part of the room, by automatically adjusting the thermostatic valve based on readings from these sensors - not just near the radiator.
Open Window Detection
The thermostat automatically turns off heating and activates Frost Protection when a connected magnetic sensor (Tapo T110) is triggered. This solution saves energy and maintains home safety.
