Firmware 5.7.1 is on my Nuki Pro. So far, I haven’t noticed any negative issues. I will keep an eye on it and report back if I encounter any problems.

I’m bringing up the problem from version 5.6.X again, which still persists. I would still appreciate feedback or even a fix.

Since the Matter improvement introduced with version 5.5.4 (“All Smart Lock state changes are now consistently indicated”), I’ve noticed the following behavior: when I activate the Lock’n’Go function (in my case by pressing twice the button on the lock manually), I immediately receive an Apple Home notification saying “The lock XYZ was unlocked.” Then, when the door closes and Lock’n’Go locks it, I get another message saying “The lock XYZ was locked.”

What I mean is that since version 5.5.4, two notifications are sent via Apple Home when using Lock’n’Go — “unlocked” (which doesn’t make sense in this context) and “locked,” which is correct. Before version 5.5.4, only the correct “locked” notification appeared after locking, not already when the button was pressed.

Could this be fixed again in a future version, please?

Still Problems that the Pro stands in Unlatch Position
