Doesn't work properly. My Google battery doorbell keeps sending notifications with previews of people but it always says can't connect to stream. I've never been able to answer the doorbell from my phone and it rarely works on my Google hubs. I wish I'd gone with Ring. That works. When someone rings the doorbell, the notification is no different to a movement detection. Also, it struggles to scroll and always freezes when trying to scroll down more than 5 items.
