My friend, have you heard of Hollow Knight?

2 in the cootie, 1 in the booty

I haven’t finished setting it up yet, so I can’t offer an opinion yet, but the way I’ve gone is a doorbell with electric lock control- mine does 2 locks, and you can set the 2nd lock to be a doorbell instead. The ‘doorbell’ output is a contact closure, which I just wired to a standard doorbell chime. Network down means I still have a doorbell.

I hate how fragmented they are. I’ve given up on various guides out there for ‘setting up the arr stack’ because of getting bogged down in since miniature detail that, IMHO, shouldn’t even be a thing. I get that hosting seperate services has advantages. But the disadvantage of giving up on the whole thing because you have to sort out networking and file permission issues between the service that downloads video files over an hour long and the service that downloads video files under an hour outweighs those advantages.
