Issues with wired 2k doorbell


I’ve installed a 2k wired eufy doorbell.

I’m having an issue getting an iPhone to connect to a google hub. When I setup the connection in Google home it says its connected but no entry shows up in Google home and the Google hub doesn’t recognise commands.

The other minor issue is when I press the doorbell I get a notification and sound on my android phone but on my mums iPhone it makes no sound only a notification.

Any advise is appreciated.
