Google Meet is now available on the Nest Hub Max – with support for Google Assistant and voice commands – as part of a beta programme.
"Hey Google, join my meeting" will take you into the next meeting on your calendar, or you can enter a specific meeting code or initiate a new meeting. Organisations can apply to the Google Assistant beta programme, which also includes Assistant integration for Google Calendar and Gmail features.
Use your G Suite account to sign up for the beta here. Beta registrations not managed by Gecko. Acceptance into the programme by Google required to unlock Google Meet and Google Assistant features during beta phase.
