Fitting M30×1.5 radiator valves, the Kasa KE100 (EU) swaps in for the thermostatic head and runs on 2 AA batteries that TP-Link says last a whole heating season. Every smart feature needs the Kasa Hub KH100. Through it the valve works with Alexa and Google Assistant, and TP-Link says a firmware update added Matter for Apple Home, Google Home, Alexa and SmartThings.
