Verified July 2026
Budget Matter-over-Thread lock that fits euro profile and UK oval cylinders (emergency function required) — a rare genuinely UK-door-friendly cheap option. Pure local control via the HA Matter integration, but you need a Thread border router and there's no fingerprint keypad at this price.

| Control | Type | What it does |
|---|---|---|
| Lock | Lock / Unlock | Standard lock control |
| Battery | Sensor (%) | Battery level — firmware v65+ only |
| Firmware update | Update entity | Notifies and installs new firmware |
HA's native Matter integration only creates three entities here — lock, firmware update, and battery (and battery only after firmware v65+) — with no jam status, tamper state, or PIN/event-log data exposed at all. Manual key unlocking isn't always picked up correctly unless the lock's motor reaches its exact calibrated position, so enabling auto-relock (repositioning the motor after any manual turn) is the practical fix. Because jam/failure states aren't visible to HA, a useful watchdog is alerting if the lock entity hasn't changed state within a few minutes of a door sensor detecting arrival.
