Even though I live in a studio apartment, when my doorbell goes off (dumb doorbell with a tiny mic next to it) I have HA set the alarm volume to max on both my phone and tablet and send an alarm trigger. It sounds like a bunch of sirens going off whenever someone rings the doorbell. But it’s not entirely pointless, because I wear noise-cancelling headphones all the time whenever I’m home, so there’s always a chance I won’t hear the doorbell going off.
