My nest doorbell will only work with one of my Google hub screens they are all on the same Wi-Fi network and same account seems to be nearly impossible to get everything talking to each other I would think it would be the basics to have the nest doorbell announcements on all Google devices in the house how is this done please
Are all of your Nest Hubs in the same Google Nest "home/structure" as your Nest doorbell and is "Do not disturb" turned off on all of them? If so, you should get "visitor announcements" on all of them. In fact, one of the complaints from some customers is that they don't want to get "visitor announcements" on ALL speakers.
You should also be able to view or stream your Nest doorbell to all of your Nest Hubs if they are in the same "home/structure".
