action.devices.traits.LockUnlock - Not executing

[Prithiviraj]

Hi, 

We have a door lock integrated with google home and it used to lock / unlock on commands like Hey Google, Lock front door, Lock all the locks.
Unlock front door, Unlock all the locks. Unlock is followed by asking PIN.
Now when i command unlock all the locks. It responds with I'm not sure which device to unlock. Previously It used to ask for pin and proceeds to unlock. Single device lock/unlock operations and "lock all the lock" operations are working.

I need assistance on resolving this issue. please let me know if you need any additional information.

Regards,
Prithiviraj

Thanks for reaching out. In instances where users request to unlock multiple locks concurrently, the system is designed to verify the specific lock to be actioned, a measure implemented for security.  This aligns with Google's ongoing efforts to refine natural language processing, enhance security protocols, and improve device integrations through regular updates.

Thank you for your response.

Thanks for the clarification regarding the current behavior of Google smart home when handling unlock commands for multiple locks.

However, I’d like to highlight that during our initial certification process, the command “unlock all the locks” was explicitly tested and verified to function correctly. It prompted for a PIN and successfully unlocked multiple devices in a single command. This was also documented in the certification feedback we received, where both “lock all the doors” and “unlock all the doors” were evaluated as expected behaviors.

Given this, could you please confirm whether the “unlock all the locks” command has been officially deprecated or restricted as part of a recent update? If so, is there any documentation or changelog that outlines this change in supported voice commands?

We got this error report during Google's certification last year.
