Matter smart locks in Home Assistant: what works and what to check
How Matter locks join Home Assistant, what you need, how PIN and user management works since 2026.4, and the limits reported against specific locks.

Each cell is a sourced record; requirements and limits per device are listed below the article. "Unknown" means no source we accept states it either way.
What you need
- Home Assistant OS with the Matter integration and the official Matter Server app. Home Assistant says this is the only supported installation type, and Thread devices need Home Assistant OS 10 or later.
- A Thread border router near the lock: Home Assistant names Nest Hub (2nd gen), Nest Wifi Pro, HomePod mini or 2nd gen, Apple TV 4K, or its own OpenThread Border Router app.
- IPv6 enabled on the Home Assistant host, and the lock, border router and Home Assistant on the same network segment.
- The phone app for commissioning, with Bluetooth on, and the lock's QR or numeric setup code.
A Matter lock joins Home Assistant like any other Matter device, and lock and unlock work. Codes are the part that varies. Since Home Assistant 2026.4 you can manage users and PIN codes from Home Assistant, but only on locks that expose Matter’s door-lock user-management features. Check that before you plan around it.
The route
- Commission the lock from the Home Assistant phone app (Settings › Devices › Add Matter device). If it is already in Apple Home or Google Home, choose “Yes. It’s already in use” and share it from that app. Matter allows several controllers per device.
- Home Assistant then exposes a lock entity: lock, unlock and state, plus battery and other sensors where the lock reports them.
- For codes, run Get lock info first. It reports whether the lock supports user management, how many users it holds and the allowed PIN length.
PINs and users since 2026.4
The 2026.4 release added a Manage lock dialog on the lock’s device page, plus actions for automations:
- Set lock user and Set lock credential. Creating a user does not let them unlock anything until you add a credential such as a PIN.
- Get lock users, Get lock credential status, and Clear lock user or Clear lock credential.
- User types include schedule-restricted, one-time (disposable), expiring and remote-only users.
Two documented limits:
- The lock never returns a stored PIN, so keep your own record of codes.
- Not every Matter lock implements user management. The action pages say to check the capability first.
Lock by lock
| Lock | Home Assistant route | Codes over Matter |
|---|---|---|
| Aqara U200 | Matter over Thread | Reported missing for at least one owner (see below) |
| Yale Smart Lock with Matter | Matter over Thread | Not documented by Yale. Check Get lock info |
| Schlage Sense Pro | Matter over Thread | Not documented by Schlage, which routes codes through the Schlage Home app |
A user report on the Home Assistant issue tracker (core#166896) describes an Aqara U200 shared into Home Assistant over Matter with no code management appearing. That is one owner’s report on one firmware, not a confirmed limitation of every U200. Run Get lock info on your own lock.
Practical limits
- Apple border routers block over-the-air firmware updates for Thread devices, according to Home Assistant’s Matter documentation. Use the maker’s app or a non-Apple border router for lock firmware.
- Home Assistant only supports the Matter Server on Home Assistant OS. A standalone container install is not supported.
- Hands-free and Home Key unlocking are Apple Wallet features. They keep working in Apple Home if you share the lock to both, but Home Assistant does not manage them. See Apple Home Key smart locks.
Other locks and platforms are in the smart lock compatibility matrix.
Known limitations
- Aqara Smart Lock U200: Platform support comes from Matter certification; Aqara does not publish a per-platform feature list for this model.
- Aqara Smart Lock U200: Keypad PIN management over Matter depends on the lock exposing Matter user-management features; check the Get lock info action before relying on it.
- Yale Smart Lock with Matter: A separate Yale product, not an Assure Lock 2 with a module.
- Yale Smart Lock with Matter: Listed by CSA as a Google Home Preferred Product.
- Schlage Sense Pro: Hands-free unlock needs a Thread-enabled Apple home hub, iPhone 11 or later (not SE 2/3 or 16e) on iOS 18.5+, or Apple Watch Series 6+ (not SE) on watchOS 11.5+.
- Schlage Sense Pro: Schlage: guest access codes, history, auto-lock and hands-free modes need the Schlage Home app.
External findings
- Home Assistant issue core#166896 (user report): An Aqara U200 owner reports that no lock-code management appeared after sharing the lock into Home Assistant over Matter. (checked 2026-11-08)
