The Shelly 2PM Gen4 comes set up for Matter.

It is a two-channel in-wall relay that measures power and runs two switches or one shutter or blind. It has Wi-Fi 6, Bluetooth and Zigbee. It suits HomeKit users, with native support through Matter over Wi-Fi. Home Assistant users get native support through Zigbee. Google Home, Alexa and SmartThings users reach it through an integration (the maker's cloud).
