Does the WeatherFlow Tempest Weather Station work with HomeKit, Alexa, and Google Home?

The Tempest Weather Station is a home weather station with no moving parts that measures wind, rain, lightning, temperature, humidity, pressure, UV and solar radiation.

It sends its readings to a Tempest WiFi Hub on 2.4 GHz Wi-Fi, works with Alexa through a Tempest skill and has Home Assistant integrations. It suits Alexa users through an integration (the maker's cloud). Home Assistant users reach it through an integration (local Wi-Fi control).
