As a hack, this is great. As a thing I would actually use? Very, very unlikely.
- I would never use a random QR code in public and I wouldn’t ask anyone else to.
- Pranking seems like an issue.
- If I know someone, they’ll text me they’ve arrived. If I don’t know someone, there are two main cases: delivery person, who is going to pound the door and leave immediately (and I’ll get a notification of delivery); and religious proselytizers, political door-knockers, and solar company sales people, none of whom I care remotely about talking to.
Again, as a project, this is delightful. But as a thing to incorporate into my home, I can’t see the use case.
EDIT: Also, criminals. They’re not going to use a QR code to see if I’m home.
