Why these: we have no US store link we can verify for this exact model. Each is a different product, certified by the CSA as the same device type, aggregator (Matter bridge), with a CSA certificate for its own model and a store link we checked. Models on the same network (Wi-Fi) come first; the order is not a ranking.

Is the Kasa Smart IoT Hub sold in the US?

MatterCatalog labels it as sold outside the US: UK version. We don't link a US store for this regional version. Its CSA Matter certificate, CSA244B2MAT43877-24, is dated Sep 3, 2024. Certification alone does not mean it is sold in the US.

What you can do

We link a US store only after its listing matches this exact model. We check only stores our rules let us read, so a store we could not check may still sell it.

The Kasa Smart IoT Hub (model KH100) is the hub that Kasa's KE100 smart radiator valves connect through. TP-Link says a firmware upgrade adds Matter: the hub's Bind to Matter setting gives the Matter setup code, and the radiator valves, sensors and other products on the hub are then shared with the Matter platform.
