The user interface for a doorbell (smart or dumb) is a a single button that you press, with your finger. Compare that to take out my phone, find a way to scan a qr code, scan it, install an app (?!?!), press a single button with my finger, on the app.

This is even supposing that I want to do that to begin with (I know for sure delivery drivers are never doing it).

Good job on the project, I really mean it. It doesn't matter what you do, it matters that you've achieved it and for that, congrats. But as a practical semi-object, this has to be one of the worst ways possible to solve the problem.

That is a valid point. The visitor does not need to install the app, but it's still more complicated than pushing a button.

From the owner's perspective I imagine it's at least a little bit simpler to install an app and put up a QR code. Although if they have to print it out themselves I guess all bets are off.

Thank you, those are kind words. I doubt that this is the worst possible way in every context, but working towards better solutions is why we share stuff and ask/give feedback :)
