Google Home does not currently support many sensors that Awair provides. For a list of supported devices types in Google Home, please visit this link.
Awair does currently provide a Google Home integration for Awair Glow's outlet and nightlight.
It is still possible to access Awair sensor readings and other information from your Awair. This can be achieved with the Google Assistant integration. For example, you can ask Google Assistant/Home (speaker): "Ok Google, ask Awair for the temperature."
