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

It reports temperature, humidity and air pressure, and runs for over 2 years on a CR2477 battery. It suits HomeKit users through an integration (a Matter bridge). Google Home, Alexa and Home Assistant users reach it through an integration (Zigbee).
