The Matter certified dimmer half of the Kasa in-wall line, for dimmable LED and incandescent loads. Dims locally from Home Assistant with no hub in the path.

Roles it can fill
Neutral required, single pole only, 2.4GHz Wi-Fi, commissioned either into the Matter integration with the printed code or into the tplink integration for local polling. Check the dimmable LED load rating on the datasheet before speccing it for a large downlight bank, and confirm the fixtures are dimmable at all: a non dimmable LED on a dimmer flickers and fails early. Three way runs need the KS230 KIT instead, since the KS225 cannot pair with a traditional companion switch.
