Does the HomeWizard Watermeter work with HomeKit, Alexa, and Google Home?

The HomeWizard Watermeter clips onto an analog water meter and reports water use over Wi-Fi.

It runs on USB-C for live readings or on two CR123A batteries, which update the app four times a day. It suits Home Assistant users through an integration (local Wi-Fi control).
