Best smart deadbolts with real Home Assistant support
Discover the best smart deadbolts that work directly with Home Assistant, offering local control and integration without cloud dependencies.

If you’re building a local-first smart home with Home Assistant at the center, a smart deadbolt is one of the highest-stakes devices to get right. A lock that depends on a vendor cloud can fail to respond exactly when you need it, and it leaks access data to servers you don’t control. This guide covers smart deadbolts that integrate with Home Assistant, and is blunt about how each one actually communicates — because “smart lock” covers everything from fully local Matter to cloud-only Wi-Fi.
Why local control matters for deadbolts
A deadbolt is a security boundary, not a light bulb. For a local-first setup you want the lock state and lock/unlock commands to travel over your own network. In practice the locks worth considering use one of three approaches:
- Matter over Thread — pairs to a Thread border router and Home Assistant’s Matter integration. Local and instant. This is the best current option.
- Z-Wave / Zigbee — pairs to a local controller (e.g. a Z-Wave stick with Z-Wave JS, or a Zigbee coordinator). Long-standing, fully local.
- Bluetooth (Yale Access) — local over BLE for some August/Yale models, but range-limited and often paired with a cloud bridge for anything remote.
Plain Wi-Fi locks that only talk to a vendor app are the ones to be wary of: they may have an HA integration, but it usually runs through the manufacturer’s cloud.
Top smart deadbolts with real Home Assistant support
1. Nuki Smart Lock Ultra (and Pro / Go)
The Nuki Smart Lock Ultra is a retrofit (it turns your existing deadbolt thumb-turn) and, importantly, it speaks Matter over Thread — not Z-Wave, and not “local via the Nuki Bridge over MQTT.” Nuki joined Works with Home Assistant in 2025, and the Ultra, Pro, and Go all pair to HA through a Thread border router and the Matter integration, with everything happening locally once joined. Nuki has stated it will keep Matter on Thread rather than Wi-Fi for battery reasons. A good choice in regions/door types where a thumb-turn retrofit makes sense.
2. A Z-Wave deadbolt (e.g. Yale Assure / Schlage BE469 with a Z-Wave module)
If you already run a Z-Wave network, a Z-Wave deadbolt is a proven, fully local path: it pairs to a Z-Wave controller (a Z-Wave stick running Z-Wave JS, or a controller like the Aeotec Smart Home Hub) and exposes lock/unlock plus PIN-code management to Home Assistant with no cloud at all. Z-Wave locks have been doing this reliably for years, and PIN management via the Keymaster custom integration is mature. The tradeoff is you’re committing to the Z-Wave ecosystem and a controller.
What about the Schlage Encode Plus?
The Encode Plus gets recommended constantly, and the hardware is good (BHMA-rated, slim, Apple Home Key over NFC). But it is not the clean local-first deadbolt people assume. It runs on Wi-Fi plus Thread, and crucially it is not a Matter device — its Thread radio is used to join Apple Home (over HomeKit-on-Thread with a HomePod or Apple TV as the Thread border router), not Matter. There is no native Home Assistant Matter path for it.
Your options with Home Assistant are therefore: the official Schlage cloud integration (works, but routes through Schlage’s servers and drains the battery noticeably), or the indirect HomeKit-bridge workaround — pair the lock to Apple Home, then expose it from Apple Home into HA via the HomeKit Controller / Actions route. The HomeKit-over-Thread path keeps the lock’s long battery life and Home Key intact, but it’s extra setup and HA can’t see things like battery level or jam state. Good lock; just don’t buy it expecting “pairs to HA over Matter.”
What about August?
August (now Yale-owned) Wi-Fi locks are cloud-dependent for their main integration: the august integration links your August/Yale account, so status and control route through the manufacturer’s cloud. The one local path is the Yale Access Bluetooth integration, which can control some August/Yale locks over BLE locally (using offline keys, often refreshed via the August integration). It works, but it’s BLE-range-limited and finicky to set up — so August is not the clean local-first choice the Matter or Z-Wave locks are. The August/Yale lock does not speak Z-Wave or Zigbee, and there’s no local MQTT path.
Additional considerations
Use a local controller for Z-Wave or Zigbee. A Z-Wave deadbolt needs a Z-Wave controller (Z-Wave JS via a Z-Wave stick, or a hub like the Aeotec Smart Home Hub). A Zigbee lock needs a Zigbee coordinator. There’s no MQTT shortcut around the radio — you need the matching coordinator.
Be skeptical of cloud-only Wi-Fi locks. An HA integration existing doesn’t mean it’s local. If the integration requires logging into the vendor’s account, assume commands travel through their cloud and will fail during an outage.
PIN-code management. If you hand out guest codes, check that your chosen lock supports adding/removing codes from HA. Z-Wave locks and several Matter locks do; the Keymaster integration helps automate this.
Quick verdict
- Best overall, fully local (Matter over Thread): Nuki Smart Lock Ultra — native HA Matter integration, no cloud account required once joined. Also the best retrofit if you want to keep your existing deadbolt thumb-turn.
- Already on Z-Wave: a Z-Wave deadbolt (e.g. Yale Assure with the Z-Wave module) on Z-Wave JS — proven and cloud-free.
- Good lock, but not a clean local pick: Schlage Encode Plus — Wi-Fi + Thread-for-Apple-Home, not Matter; HA access is cloud or a HomeKit-bridge workaround.
- Avoid as a local-first pick: August/Yale Wi-Fi locks — cloud-dependent, with only limited BLE-local control on some models.
The common thread (literally): for genuine local control, pick a lock that pairs over Matter/Thread or Z-Wave, and steer clear of anything that needs a vendor account to function.
