Support of door lock U200

[Darkdragon14]

Hi 👋

Following the request from @SanValerius, I’ve created this sub-issue to track the integration of the Aqara U200 Door Lock into the integration.

The goal is to support the device as cleanly as possible through the Aqara Cloud API, similarly to how other devices are currently handled.

Hi 👋

I’ve started looking into the U200 support and made some progress on my side.

However, I’m currently unable to find any reference to the U200 in the official Aqara API documentation I have access to. I searched by model name (including possible lumi. identifiers) but couldn’t find anything related to this device.

Could you please provide:

• The exact model identifier (usually something like lumi.xxxxx)
• Or any API payload / device info JSON from the Aqara developer console
• Or confirmation if it’s exposed through a specific hub (G3, M3, etc.)

Without documentation or a device to test with, it’s a bit difficult for me to properly implement support.

Thanks again for your request and your help 🙏

Hi @Darkdragon14 ,

I would like to assist you, I never connected to Developer console until now, so guide me if required ;-)

On the API doc at that moment I found an entry for U100 but not U200

Some deeper diag:
Here is a summary of what we discovered throughout this session:

• Correct Europe endpoint: https://open-ger.aqara.com/v3.0/open/api (not open-eur.aqara.com which was down)
• Signature method: MD5 of Accesstoken=x&Appid=x&Keyid=x&Nonce=x&Time=x + AppKey (all lowercase), without a separator before AppKey

Current findings:

• query.resource.info returns {} — the Matter model aqara.matter.4447_10242 has no declared resources in the Aqara API
• query.resource.value returns "all resource not open" — resources need to be subscribed first
• query.device.info returns data but needs to be expanded with ConvertTo-Json -Depth 10

So direct API to U200 not OK (Matter connexion).

then I went through the M3 Hub and got this but I believe they are the "M3" fields themselves and not the U200?

Via the M3 I got this so I'm not sure but feel that Aqara doesn't expose much U200 via API or ?

I found that for Matter devices you can get some info from the API Trait https://opendoc-test.aqara.cn/en/docs/developmanual/apiDocument/trait-codes.html , from that you can get the door status, battery percentage and issues commands to lock/unlock

U200 API trait.txt

what's a shame is that it will not add anything more that what We natively have via the Matter component:

Hi 👋

Thanks a lot for providing all this data — it's really helpful.

I’ll take some time to analyze everything and see if it can be integrated into the integration. I’ll come back to you once I’ve had the chance to properly review it.

Also, thank you for your investment and the time you took to gather and share all this information, it’s really appreciated. 👍
