Smart lock that works with Home Assistant and doesnit require internet

Hello! I’ve been looking around and reading various posts people have about smart locks but I haven’t seen any that have answered a few questions I have.

I have HASS set up on a server of mine and I have a UDM SE with a G4 Doorbell Pro. I’ve been trying to see if I can find a smart lock that can work with HASS, even if I don’t have internet where I can use the fingerprint reader on my doorbell (using a local webhook), or an NFC card on it. etc. I’d love it if the lock itself didn’t do much, but I recognize that most of them will have a keypad that I could just not use.

Something else I’d like is, due to living in a rental, I want to re-use my own key. I can always give the landlord a code or something, but ideally I could just reuse the key I have so as to not cause any further conversations with my landlord.

I don’t currently have any Z-wave or Zigbee products, so if I needed to buy something like that I can, but I definitely don’t want something that requires the internet to access or a separate app to configure.

If that’s all too much to ask for, then I can settle for one or two of those requirements, but I’d be greatly appreciative if I could find something that I can maybe just use an app to connect to wifi, but a HASS integration could then control it so I could avoid using internet entirely.

Thanks in advance!

I’m unsure of exactly what you’re after because you mention landlord, rental situation but from what I can see you have Unifi network with a G4 doorbell in place. If you want a smart lock that is rental-friendly go with the Level Bolt. This device will fit into your existing lock hardware without outward-facing hassle. Your G4 probably exposes an entity for fingerprint sensor that you can use to trigger the lock as needed and existing keys will still work.

I make my recommendation hesitantly because Level (the company) is slow-rolling support for matter into their existing hardware lineup. I have a Level Bolt that they recently upgraded to Matter (this is awesome!) but have refused to do so with a later-generation Level Touch which is hardware compatible but they want me to buy a new lock to get that functionality. Don’t expect more than what is currently advertised for the product you buy.

Nuki has an ESPHome integration that lets it seamlessly connect to HA.

You are correct in that I’ve got a little Unifi setup and that I’m renting. I don’t mind making changes, but they need to have a key to get in.

The G4 does expose a few things for the reader, so I already have it set up to send a webhook to HA and then ping my phone for testing, but I want to make sure that I can control it locally with HA addons.

If the Level Bolt works without changing my key, and it can be pinged from my HA instance without needing internet, then I think that might be the route to go.
