Re: Online only? That's the idea...
And isn't annoying when people turn up and use the knocker anyway?
Our Ring is just 'the doorbell' (plus a couple of Chimes - one upstairs, one downstairs). We don't have a knocker or any other non-IoT doorbell, but I reckon that about 80% of callers physically knock on the door instead of pressing the bloody bell-push. And it's not like you can miss a Ring doorbell - they're about the size of a Nokia 3310.
I know they're there because of the proximity warning. The problem is that the local cats can trigger an identical warning, though none of them have - as yet to my knowledge - mastered pressing the button. I just wish the postman could best the moggies and do so in order to differentiate himself.
