Quick answer
Matter-over-Thread connects these locks through compatible infrastructure, but door format and ecosystem-specific access features still differ.
Research shortlist
Matter-over-Thread connects these locks through compatible infrastructure, but door format and ecosystem-specific access features still differ.
| Product | Research use case | Sourced features | Decision limit |
|---|---|---|---|
| Aqara Smart Lock U200 | Controller and border router | Matter: Yes; controller and Thread border router required; Thread: Yes; Apple Home: Yes; compatible Matter controller / Thread border router | Identify both roles; a Matter controller does not automatically provide the Thread radio path. |
| Level Lock Pro | Lock format | Matter: Yes; compatible Matter-over-Thread controller; Thread: Yes; Apple Home: Yes; home key and Matter | U200 is a retrofit actuator; Level Pro and eufy E31 are deadbolt replacements. |
| eufy Smart Lock E31 | Platform feature scope | Matter: Yes; Matter hub required; Thread: Yes; Matter over Thread; Apple Home: Yes; Matter. Apple home key explicitly not supported | Check which lock functions your selected ecosystem exposes rather than transferring vendor-app capabilities. |
What to check before buying
| Decision factor | What to establish |
|---|---|
| Controller and border router | Identify both roles; a Matter controller does not automatically provide the Thread radio path. |
| Lock format | U200 is a retrofit actuator; Level Pro and eufy E31 are deadbolt replacements. |
| Platform feature scope | Check which lock functions your selected ecosystem exposes rather than transferring vendor-app capabilities. |
| Home key | Level and U200 document home key; eufy E31 explicitly does not. Matter support does not imply that feature. |
Aqara Smart Lock U200
Why it belongs here: For controller and border router, the US / Europe / global record documents Matter: Yes; controller and Thread border router required; Thread: Yes; Apple Home: Yes; compatible Matter controller / Thread border router; NFC: Yes; Apple home key and Aqara NFC cards.
Who should consider it: Buyers assessing controller and border router who can meet the documented Aqara Smart Lock U200 installation and operating requirements.
Before choosing: Identify both roles; a Matter controller does not automatically provide the Thread radio path.
Evidence limit: Aqara Smart Lock U200 is assessed for controller and border router using manufacturer documentation; this does not establish a comparative security test result.

Why it belongs here: For lock format, the US record documents Matter: Yes; compatible Matter-over-Thread controller; Thread: Yes; Apple Home: Yes; home key and Matter; NFC: Yes; home key and included key fobs.
Who should consider it: Buyers assessing lock format who can meet the documented Level Lock Pro installation and operating requirements.
Before choosing: U200 is a retrofit actuator; Level Pro and eufy E31 are deadbolt replacements.
Evidence limit: Level Lock Pro is assessed for lock format using manufacturer documentation; this does not establish a comparative security test result.

Why it belongs here: For platform feature scope, the Australia record documents Matter: Yes; Matter hub required; Thread: Yes; Matter over Thread; Apple Home: Yes; Matter. Apple home key explicitly not supported.
Who should consider it: Buyers assessing platform feature scope who can meet the documented eufy Smart Lock E31 installation and operating requirements.
Before choosing: Check which lock functions your selected ecosystem exposes rather than transferring vendor-app capabilities.
Evidence limit: eufy Smart Lock E31 is assessed for platform feature scope using manufacturer documentation; this does not establish a comparative security test result.
Full sourced specification recordHow we chose
Selection centres on controller and border router, lock format, platform feature scope, home key. Matter-over-Thread connects these locks through compatible infrastructure, but door format and ecosystem-specific access features still differ. This is source-based research, not a hands-on test or star-rated ranking.
Read the complete methodologyCommon questions
Do I need a Thread border router?
For these Matter-over-Thread products, use a compatible controller and border router setup as required by the manufacturer.
Will every feature work through Matter?
No. Confirm supported commands and credential functions in the exact ecosystem; home key and app features are separate capabilities.
