Does the SONOFF SNZB-02DR2 work with HomeKit, Alexa, and Google Home?

Its 3.6 inch LCD shows temperature and humidity, and can also show the reading of another SONOFF sensor on the same gateway. It suits HomeKit users through an integration (a Matter bridge). Google Home, Alexa, SmartThings and Home Assistant users reach it through an integration (Zigbee).
