TP-LINK Kasa KE100 Smart Thermostatic Valve

The TP-LINK Kasa KE100 is a white smart radiator valve that cuts heating waste by letting you control each radiator from your phone—no more paying to heat empty rooms. Pair it with the Kasa Hub KH100 and you unlock scheduling, geofencing, and voice control via Alexa, Google Assistant, or Siri.

Heat on your terms, not the calendar

• Geofencing learns your routine: heating ramps up as you arrive home, shuts down when you leave
• Runs on 2 AA batteries for over a year, with no additional hub needed for basic scheduling
• Fits most radiators via M30×1.5 thread plus six included adapters (RA, RAV, RAVL, CAL, M28, GIA)
• Open window detection pairs with compatible door sensors to auto-disable heating and activate frost protection

Ideal for anyone paying for heat in rooms they don't use, or looking to trim energy bills without sacrificing comfort. Works best in homes with multiple radiators and a Kasa Hub.
