Google Home: devices you map for Google Home are listed in the Google Home app with their room, and can be switched, dimmed, colored, set to a temperature or mode, locked, opened or set to a fan speed. Temperature, humidity, contact and motion sensors report their readings.
Google Home: every answer to Google reads the device's current value, and with state reporting turned on, changes are pushed to Google as they happen, at most once a second.
Voice assistants: HomeKit, Alexa and Google Home are now separate integrations. Install the one you use from the Extension Catalog.
Bug Fixes
