matter smart lock with Google Home App issue

[mt0msk]

Hi,

I test matter smart lock with Google Home App.

I got problem.

I unlocked the smart lock from Google Home App, then Google Home App shows error that looks like this.

"this function is not support".

And, matter smart lock published lock/unlock status.

The status of the smart lock is not reflected on the Google Home App screen.

When I reload the screen on Google Home App, the status of the smart lock is displayed.

My environment is as below.

Google Nest Hub 2nd
 System FW : 14.20230831.4.72
 Cast FW : 3.71.387262

Pixel 7 Pro
 Google Home App : 3.11.1.10
 Android : 14
 Build : UQ1A.240105.004

Matter SDK: v1.2.0.1

Thanks for bringing this up. In the current implementation remote unlock is disabled on all surfaces for Matter door locks in the Google ecosystem that don't mandate a PIN code. When fulfilling an unlock command, if requirePINForRemoteOperation is set to false, Google Home users receive a message saying that device cannot be unlocked remotely.

If requirePINForRemoteOperation  is set to true, it means that a PIN code is required for remote unlocking. In this case, you need to implement a PIN per Google Home requirements If you never setup PIN code through Google Home previously, there is usually a master PIN code set up on the lock. This master PIN code is typically established right before the Google Home setup. Users should use this master PIN code for remote unlocking through Google Home, and it should work as expected. It serves as a security measure to ensure that only authorized users can remotely unlock the device.

For the issue with updating the status for Lock in Google Home, can you please share the video of the issue?

Thank you for your reply.

I enabled requirePINForRemoteOperation.

How do I set up PIN code?

I set up the matter smart lock on Google Home, however, Google home did not ask for PIN code during set up.

When I try to lock/unlock the matter smart lock, Google Home requests PIN code.

And, I did not know master PIN code.

Therefore, I cannot lock/unlock the matter smart lock.

Regarding updating the status for lock, I will try to take a video.

Hi, I'm sorry for delaying.

Google Home App cannot set PIN code.

Therefore, I set PIN code from Apple Home App.

And, I take the video.

1. I controlled lock from Apple Home App.

Lock status on Google Home App was not changed.

Google Home App needs to reload.

Control from Apple Home

2. I controlled Lock from Google Home App.

Lock status on Apple Home App updated without reload.

I got the same problem. I cannot set up a PIN code in the Google Home App? Did you manage to fix this?

Google has resolved the issue. Finally, I can unlock my door (e.g. NUKI) without an error message.
