Thanks Stefan,
There are 3 HomePods mini and an AppleTV as possible Thread Boarder Routers.
Is it possible to go back to Nuki Bridge as Remote Access Device if I install the 4.1.3 firmware and use Thread for Remote Access?
Is the paired Keypad still working as normal via Bluetooth ?
Will i am forced to pay the planned fee for thread remote access when the feature becomes official or can I return to Nuki bridge access then?
You can pair the Bridge again after the update and everything will work as before.
Keypad is not affected.
Since I have my new Smart Lock Pro (4) I have an instable WLAN connection to my Fritz Box 7590AX.
After 1 or 2 days the Smart Lock will lose the connection and I have to disconnect the batterie to get WLAN again. Reset the Router or only disable the WLAN of the Smart Lock will not help.
Support told me to try the Beta Firmware, but same problem here. Am I the only one with this Problem?
Original post has been updated with the additional information on using the compatible App beta versions:
Note:
Please use this firmware in combination with the most recent App beta versions:
Please install the App beta as well to get the full experience in utilizing the new remote access capabilities of your Smart Lock (4th Generation).
Since the current beta update the lock looses the WiFi connection. Even a restart of the lock does not help.
Only if I restart the fritzbox 7580 it connects to the WiFi.
I am trying to enable the debug mode on my SmartLock 4 Pro with door sensor. The lock is running Beta 4.1.3 and I am using TestFlight iOS app 2024.2.1 (2506), but when I click 6 times on the Functions and Configuration header it tells me I need to run the latest software on the SmartLock. What to do?
BTW the reason I need to run Debug mode is that I can use the lock with the front door in our small theater that has a “panic” handle on the inside that unlocks the door at all times, whereas the outer handle only opens the door when it is unlocked (either by key or by somebody using the inside handle before.), see Notification or Auto-Calication for cylinders with panic function
I was only able to activate remote access via Thread for one of my two Smart Lock 4.0 Pro. On the second device, “activating remote access…” spins for a few seconds, then disappears and the switch remains disabled.
Original post has been updated with release notes for the Smart Lock Beta 4.1.4 and Smart Lock Beta 4.1.5.
These Beta versions include several stability improvements for the remote access connection via Thread as well as for the WiFi connection.
We kindly ask all of you to update your Smart Locks manually with the Nuki App to version 4.1.4 and let the update to the version 4.1.5 then happen automatically over night.
As usual please provide your feedback via this channel - thank you!
With the new firmware the Smart Lock implements the ability to provide the full remote access capabilities via the Nuki app by using the Thread uplink from a Matter pairing if it is supported by your Matter hub*. There are several ways on how this feature can be enabled, depending on the Smart Lock variant and its surroundings:
If your Smart Lock is paired to a Nuki Bridge you can cut this connection by opening the Matter settings in the Nuki App and clicking onto the button Delete Bridge connection, after that the remote access via Matter is automatically established. If you have a non Pro Smart Lock a one-time payment is necessary to activate it.
If your Smart Lock is connected to WiFi it will automatically close this connection and establish the remote access connection via Thread. If the Thread network does not provide an internet connection or becomes unavailable it will continue to use WiFi.
If you want to change the remote access connection from Thread to WiFi you have to simply disable the Remote Access in the Matter settings. After that ensure that WiFi is correctly set up.
If you want to change the remote access connection from Thread to a Nuki Bridge you have to simply pair the Nuki Bridge using the Nuki app. This will automatically turn off the remote access via Thread
*Please keep in mind that the remote access via Thread is for now only supported by Apple devices (HomePod, HomePod Mini, Apple TV) and Home Assistant.
I still cannot enable debug mode after upgrading Smart Lock Pro 4 to 4.1.5, get the same message that I should upgrade it first.
Would it possibly be different when I try from an Android device instead of iOS?
Hi, with version 4.1.4 lock disconnects randomly from matter. HA matter addon shows:

After removing and inserting the batteries it connects again (done at 15:24h).
Randomly online stops working but it is available with matter.
Same here.
Thread remote connection is sometimes lost. Firmware 4,1.5. Reconnection only works by removing the Locks battery for some seconds.
Don’t know exactly if this would happen in FW 4.1.3 too…. as this version runs only for 3-4 days. But during this testing period it never happened in 4.1.3.
In 4.1.5 it happened 2 times in one day.
Original post has been updated with release notes for the Smart Lock Beta 4.1.6
This Beta improves the reconnect handling for WiFi connections as well as the performance of the Thread radio, therefore we are asking all of you suffering from a bad WiFi connection to install this build and to provide feedback on the overall connection stability with this Beta build.
Thank you! 
Now thread communication is very good with this version of firmware. Just turn on the Nuki application and you are connected.
Thanks Stefan!
No problems with thread connection but online is not very reliable, but not sure if the problem is with the nuki iself, HA matter addon or HA OpenThread Border Router addon…
Since the lattests beta updates I have the disconnect events (like other users) but I have experienced a couple of times that the unlach “open” but not releases and stay blocked until I press the button. Any body in the same case or its only my nuki device (I dont see this behaviour until the lattes beta firmwares)
Battery level still on 100 % bug.
Lock & go function sometimes is activated with just one click when nuki is configurated with 2.
