What lock actions does Matter support?

This article concerns:

With Matter, you can unlock and lock your door. Matter 1.2 also distinguishes between the actions ”Open door” and ”Unlock”.

Note:

Currently, the distinction between ”Unlock” and ”Open door” is only available with Home Assistant as a Matter Hub. But don't worry: All other hubs will perform the unlocking action you've configured in your Nuki app. This is how we make sure your door opens the right way. 

Why do I need the distinction between ”Unlock” and ”Open door”?

The Smart Lock is suitable for doors with handles as well as doors with knobs or bars on the outside. It can not only lock and unlock your door but also open it. When opening the door the key is turned until the latch is pulled, allowing the door to be pushed open easily.
This distinction between the actions ”Open door” and ”Unlock” is particularly important for European door locks. Therefore, we have actively worked within the Matter organizations to expand the Matter standard for European locks.
With success: While Matter 1.0 did not distinguish between the actions ”Open door” and ”Unlock”, both lock actions are implemented in the new Matter 1.2 standard.
