  • If you have an old bell built into the door you can hook the old button up to anything like an esp32, and if you don’t and therefore need to put a wireless button on the door (like a battery operated ring) you can do the same with an esp32 plus a battery.

    You could probably even buy any random old wireless doorbell and make it ‘smart’ by reading the output of the speaker unit.

    On top of that, putting a camera through the peephole if available is also much easier than one would guess.
