Does the Shelly 1PM Gen3 work with HomeKit, Alexa, and Google Home?

The Shelly 1PM Gen3 gets Matter over Wi-Fi after a firmware update.

It is a one-channel in-wall relay that measures power and has Bluetooth. It suits Google Home, Alexa and SmartThings users through an integration (the maker's cloud). Home Assistant users reach it through an integration (local Wi-Fi control).
