Does the WaterGuru SENSE S3 work with HomeKit, Alexa, and Google Home?

The WaterGuru SENSE S3 is a solar-powered pool and spa water tester that measures pH, free chlorine, total alkalinity, cyanuric acid and calcium hardness daily, plus pump flow and temperature.

It reports through the WaterGuru app on iOS and Android and works with Alexa and Siri, and WaterGuru says Google Home support has ended. It needs no app subscription. It suits Alexa users through an integration (the maker's cloud). It does not support Google Home.
