Nuki Fob 2: "Unknown error 0xFE" in Activity Log after opening door

Hello. I am a new Smart Lock 4 Pro user (so far, so good :slightly_smiling_face:). I also bought one Fob 2, and whenever it is used for opening (unlock+unlatch) the door, an error message is logged (the door gets opened):

As it can be seen, locking the door with the same fob does not log any error.

The Smart Lock 4 Pro is using firmware 4.2.8, and the fob was automatically updated to 4.10.1 upon pairing.

Any ideas? Should I ignore that error?

Same error here.
Not always, but very often.
Smartlock is brand new.

Firmware Smartlock (4 pro) is 4.2.8 too.
Firmware Fob was 1.8.1, change to 1.10.1 did not solve the issue
Firmware Keypad is 2.2.1

There is no obvious mechanical issue. Everything runs smoothly.

Communication with integrated WLAN and bluetooth is sometimes very laggy.
Takes much longer than with V1 Nuki with Bridge.
Using old bridge with Nuki 4 pro is also very laggy.

Hope this info helps to identify the issue.

Me too! Brand new Nuki Smartlock 4 Pro.

Hello @jmalcaide, hello @gruru ,
thanks for your feedback on that behavior. We will look into that topic.
You can follow the Smart Lock (4th generation) Beta channel. If we can reproduce the problem and have a solution, the solution will be rolled out there.

Best regards
Okko

Same issue here. Nuki 4 Pro.

Any news on this?

Having this issue with the keypad 2.0 and lock 4 pro upon locking with the keypads back button. Everything running smoothly besides that.

It’s exactly the same for me.

Here too … brand new lock. Really annoying.

Same problem here! Nuki 4 Pro + Keypad 2 - brand new.
Problem comes while opening and closing.

The same error too


The same, and the worst is that the door is actually unlocked but the log is showing this incorrect statis

I bought my brand new Nuki 4.0 Pro and a door sensor yesterday.
After get all installed I am receiving the same message in the log: Error desconocido (0xFE), along with three high-pitched beeps. The lock opens and closes seemingly well.
The conection status appears in green, in fact, the Nuki is only 5 meters from the router.
