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.
