⚡ At a Glance
- • Heating Control: Geofencing, schedules and group control align room temperature with occupancy.
- • Best for: Households wanting room-by-room heating control and practical energy savings.
- • Not ideal for: Homes that require central boiler or whole-house thermostat control.
Supports geofencing, external sensors and open-window detection for targeted heating. Requires a Kasa Hub KH100 and controls radiator valves only.
Warm rooms on arrival – thanks to geofencing support
Geofencing uses your phone location alongside the Kasa Hub KH100 to detect when someone is approaching or leaving. The valve adjusts opening automatically according to those presence signals.
Arrive to a comfortable room without fiddling with controls and avoid heating empty rooms.
Simplified multi-radiator control – with in-app scheduling and grouping
Create heating schedules in the Kasa app and group several valves so a single command applies to every radiator in a room. Group control synchronises temperature changes across multiple valves with one tap.
Set daily routines and control several radiators at once to reduce wasted energy and hassle.
Frost and open-window protection – with external sensors and auto shut-off
Supports external temperature sensors (Tapo T310 or T315) for a more accurate room reading and reacts to a Tapo T110 window sensor by shutting the valve. A frost-protection mode keeps pipes safe when temperatures drop.
Prevent frozen pipes and stop heating while windows are open, keeping rooms stable and saving energy.

❓ Frequently Asked Questions
Q: Do I need any additional hardware to use the radiator valve?
A: Yes. The KE100 requires a Kasa Hub KH100 to work, as stated in the product information.
Q: Can the valve control my central heating boiler or whole-house thermostat?
A: No. The KE100 can only control radiator valves and cannot be used to control a central boiler or central thermostat.
Q: Does it work with Alexa, Google Assistant and Tapo sensors?
A: Voice control is supported with Alexa and Google Assistant. Product details also list support for Tapo external temperature sensors (T310/T315) and Tapo T110 for open-window detection, while a note in the app requirements says "Doesn't work with Tapo", so confirm compatibility on the official listing before buying.
🏆 Our Verdict
The Kasa Smart Thermostat Radiator Valve suits households that want precise, room-level heating control without replacing a central system. Geofencing, grouping and external-sensor support are the features that make targeted heating simple and practical. Requiring a Kasa Hub KH100 does add an extra step, but the potential long-term energy savings and convenience justify the setup for many homes.
