Compatibility
| Ecosystem | Support | The catch |
|---|---|---|
| Amazon Alexa | WorksWorks with this ecosystem | Needs an Alexa device that is both a Matter controller and Thread border router (e.g., Echo 4th gen). |
| Google Home | WorksWorks with this ecosystem | Needs a Google Thread border router (e.g., Nest Hub 2nd gen, Nest Hub Max, Nest Wifi Pro). |
| Apple Home | WorksWorks with this ecosystem | Needs an Apple Home hub with Thread radio (HomePod mini, HomePod 2nd gen, or Apple TV 4K with Thread). |
| SmartThings | WorksWorks with this ecosystem | Needs a SmartThings hub that provides Thread border routing (e.g., Station, Hub v3/2018+, Aeotec). |
| Home Assistant | WorksWorks with this ecosystem | Via Home Assistant's official Matter integration; requires the Matter server add-on plus a Thread border router. |
Protocols: THREAD · MATTER · BLUETOOTH
Needs before it works: Matter controller + Thread border router (Aqara states a 'Matter Controller & Thread Border Router 2-in-1 is required' — e.g., HomePod mini/Apple TV 4K, Nest Hub 2nd gen, newer Echo devices, or Aqara Hub M3). No Zigbee or hub-free path exists.
Subscription reality
✓ Works without a subscription: Yes.
Maintenance reality
- Batteries: CR123A x1 (included)
- Cloud dependence: No — core function survives without the vendor's cloud
- Rated battery life NOT stated on Aqara's official product/spec pages (only 'infrequent replacements') — left unrecorded rather than estimated. Matter-over-Thread runs locally; no cloud dependency for core function.
The catch
It is Matter-over-Thread only — without a Thread border router plus Matter controller already in the home it does nothing, and Aqara's own listing notes the Aqara Home app is not currently supported for this device (planned via OTA), so Aqara-app-specific features are unavailable.
Who it's for
Suits households that already own a Thread border router (HomePod mini, Apple TV 4K, Nest Hub, newer Echo, or Aqara M3) and want a local, multi-ecosystem contact sensor without committing to an Aqara Zigbee hub.
