Does the SONOFF SNZB-02UL work with HomeKit, Alexa, and Google Home?

The SNZB-02UL (AirGuard E-Ink) needs a Zigbee 3.0 hub or coordinator.

It has a 2.9 inch E-Ink screen that shows temperature and humidity, and also the time, date and weather once it is connected to a gateway. It suits HomeKit users through an integration (a Matter bridge). Google Home, Alexa and Home Assistant users reach it through an integration (Zigbee).
