Does the SONOFF Hydro DUO work with HomeKit, Alexa, and Google Home?

The Hydro DUO is a two-channel Zigbee 3.0 water valve with a flow meter, an IP65 rating and a brass inlet.

It runs on four AA batteries or USB-C, and SONOFF lists a proximity mode that works without a 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).
