Does the SwitchBot mmWave Presence Sensor work with HomeKit, Alexa, and Google Home?

The mmWave Presence Sensor works without a hub and links locally to a SwitchBot Bot, Relay or Light.

A hub adds fuller automations and Matter. It runs on batteries. It suits Google Home, Alexa and SmartThings users through an integration (the maker's cloud). Home Assistant users reach it through an integration (Bluetooth).
