The Google Duo Video Call App can now be used with your Google Home Hub ($ 1
The only catch is that there will be no video. If you would like to make a call with Duo, it is nice to know that you can use your device as needed.
How to Make a Call
To make a call, you only need to say "OK, google, call a duo call". Google Assistant asks who you want to call. After answering the call, the call is connected. To hang up, say "OK, google, hang up."
If you use a hub, you can use the touch screen to choose who to call and hang up.
Calling Other Devices
You can also call other Google devices in your home. If you're asked for a name by Google Assistant, use the name of the other device instead of a person's name.
