Traditional doorbell needs an electrically powered button on the exterior.
Phone needs visitor to have your private contact info or you would need to publicly add a note with that to your door.
- sam29681749 2y agoIf you don't want to use electricity, you can have a knock. What reason would you want to be notified of unknown visitors knocking on your doors when you're away? The only people I can see fitting this description are delivery drivers & salesmen? Further, what if you're home and your phone is in another room, is on silent, or is dead? What is you have a spouse or housemate? Do both of you get notified? And there's also a subset of people who get frustrated by having to use QR codes in restaurants, who I suspect would be equally frustrated by this.
- eesmith 2y agoThere are battery powered remote doorbell buttons. Eg, $29 at Ace Hardware, with a 100 foot range - https://www.acehardware.com/departments/hardware/safety-and-security/doorbell-and-accessories/3318276 https://www.acehardware.com/departments/hardware/safety-and-... . Also, a real traditional doorbell is mechanically coupled to the bell, with no electricity at all.
