Ahh! So it's not the ESP that has an extra connection, it's the relay breakout board.
That makes much more sense.
Yeah, I guess you would need to sound the doorbell every boot, and that might be inconvenient in places with a lot of power supply issues / loadshedding.
That said, that quick-boot-button link? That's some brilliant info right there.

Funny that the store bought wireless doorbell I have does exactly that. :D I guessed it does that to avoid/reduce returns from people who doesn't manage to pair it with the doorbell button and think that it is "not working". So pre-emptively they do a chime right after you plugged in to show that it is working.
