Smart Lock 4th gen problems with iOS 17.4 Matter integration (missing notifications and slow state updates)

beta

@SAli

I am experiencing exactly same issue with matter and homepod mini ios17.4. Loosing remote connection and even bluetooth does not work properly! So my nuki 4 becomes unusable!
I disconnected my nuki from matter and now connected via wifi. Will this help and solve the issues?
I am not a beta tester so cannot download homepod os 17.5. Any other solution?

Hi,
17.5 beta not fix the problem with Matter .
The matter issue not just from Apple !also with nuki smart lock 4 .
The only solution is to connect via Wi-Fi ( The Wi-Fi connection is also currently unstable ) But it is the best solution until a new update is released from nuki

Hi,

Facing same issues that notifications not popup from HomeKit only from
Nuki app not responding was solved after update HomePod mini to 17.5 but about the notifications from HomeKit

[Gamliel_Alon]

Hi @Juergen

The notifications from HomeKit should be fixed from Nuki side or Apple also the delays from
Nuki

17.5 beta?

[Gamliel_Alon]

Hi @Juergen Yes it’s final beta status on home is ok after the upgrade notifications still have some delays less delay but still delays notifications from
HomeKit still not working

@Gamliel_Alon

notifications still have some delays less delay but still delays notifications from
HomeKit still not working

What do you mean by that? Is it that Nuki notifications are working but Apple Home notifications not?

[Gamliel_Alon]

Hi @Juergen

Yes Nuki app notifications are working with small delay but notifications from HomeKit completely not working when you open from Nuki app.

Usually the notifications was from both with no relation from where you do operations like locking unlocking.

Also noticed that on HomeKit the device firmware is not updated for example I’m using 4.3.4 and if I go to properties from HomeKit for the device firmware is 4.1.0 I have also Nuki 3 that works perfect just as fyi. And firmware is also correct.

I tried also reset the Nuki reads to home still firmware is not correct and not only on my device also my friend device

I have just updated my Apple TV 4k (which is acting as border router) to tvOS 17.5 final, and now its status does not get updated at all in the Home app (with tvOS 17.4.1, status updating was simply slow). It constantly reports “No response”. Tested from iOS 17.5, iPad OS 17.5 and macOS 14.5.

Also, the Home app continues reporting that the SL4P firmware version is 4.1.0 (actually, it is running 4.2.8). This was also happening with tvOS 17.4.1.

My S4LP connection status (on the Nuki app) shows that everything is fine. It is not using Wi-Fi; only Thread (with remote access) and Bluetooth.

I installed tvOS 17.5 and the state is working normal. Maybe you can restart Nuki and aTV? I hope that it works for you too…

[jmalcaide (Jose M. Alcaide)]

I just restarted the Apple TV and now the status of my SL4P gets updated correctly in the Home app. I did not tried that before, because the Apple TV is automatically restarted as part of the tvOS updating process. Still reporting 4.1.0 firmware, however.

Thank you very much for your advice!

Hello, iOS 17.5 is installed but I still don’t get any notification from HomeKit when my smart lock 4 pro is locked or unlocked, either through Siri or by pushing the button directly.

Should I set something up on nuki side ? In HomeKit notification is set. Thanks for your help.

My nuki firmware is up to date. My nuki and Apple devices have been restarted.

[schmidt787 (Florian Schmidt)]

With 17.5. all works great with HomeKit → Can you restart your matter border router (HomePod oder AppleTV) and the Nuki lock? Does it help?

[alext77 (Alex)]

Hello, Thanks.

I have restarted my appleTV and the nuki (by removing the battery) but the result is the same. I own HomePod as well, I can try to force them to become the matter bridge, I will try.

[Tom_Muckert (Tom Mückert)]

Same here. Everything updated to 17.5.1 or latest available version . restarted everything. no messages from the smart lock via apple HomeKit .

[Alex_Astap]

I don’t have any notifications either. The status is correct.

[ShadShad (Shadi ElSawaf)]

Hello, the Homekit notifications are not working for me also. I have the latest Nuki firmware and latest iOS, HomeOS, TVOS.

I have restarted the Apple TV and HomePod and the Nuki smart lock. I have even removed the Nuki lock from the Nuki app and the Apple Home and re-added it.

What I noticed is that notifications work when I trigger the action through Siri, the Home app or the Eve Home app. the notifications don’t trigger when an action is done on the Lock manually or automatically (Auto lock and unlock)

[alext77 (Alex)]

Hello. Thank you. It is exactly the same as you. Very frustrating. I’m pretty sure the issue is on nuki side.

[Francisco_Hernandez]

Hello!
I have the same issue. No notification in Homekit.
IOS 17.6 /17.6.1
Nuki 4.31

[ShadShad (Shadi ElSawaf)]

Any updates from Nuki? I guess there are enough people with the issue to point it’s not an Apple issue. Also, there have many multiple iOS updates and the issue is still there.
@Juergen can you update us please. Thanks

• The issue still exists within iOS18/tvOS18.
• It does also exist with other Matter locks and is not Nuki related.
• We’ve reported it to Apple.
