Aosu - V8S

I have an Aosu V8S doorbell and it shows as a camera and I can't use voice announcements

I second this. Had it since last summer and no complaints. Just get a micro sd card for saving.

i guess its model specific. Here is an Aosu video doorbell camera. In google home it just shows as a camera, can't even see the feed although I used to be able to. No option for visitor announcements. I've also had some customers with tuya based china doorbells, same issue. The point of proving was because my experience was opposite to yours, as seen from my screenshot contradicting yours. So it seems not "any" doorbell that integrates with google home can produce visitor annoucements. However I stand corrected as you have shown that yours do, so I guess some models do allow for visitor annoucements. https://preview.redd.it/ebren6veyp8e1.jpeg?width=904&format=pjpg&auto=webp&s=3886b4e8f28a9021eba6cb36ef50e88f8d620118

All Google Assistant doorbells do this. Open Google Home app, go to live view for the doorbell, ‘…’ icon top right, Settings, then turn on Voice Announcements. It explains exactly what what this option does on that page, which is produce visitor announcements on GA speakers which of course includes the Google Home Mini. Not really sure what the point of “proving” this is but here are some screenshots of this setting for the Reolink doorbell. It works exactly as OP wants, ie chime on a Google Home Mini when the doorbell button is pressed. https://preview.redd.it/ljjk8i5ddp8e1.jpeg?width=2358&format=pjpg&auto=webp&s=7adfd732599ad20e40fb70566a177af3b821aac0 I also have Arlo and Aosu doorbells on other properties which work in exactly the same way, also chiming to one or more Google Home Minis. This has worked for many years.

I have the aosu one from Amazon, it's pretty good and not subscription based

aosu works pretty well for me
