I installed them and didn’t notice any errors or interruptions.
Just to add another data point: no issues here with 5.6.4 so far.
I have since lately when I go to work and come back 8 hours later, the door no longer opens automatically.
If I leave home, I will see geofance abandoned.
This is what I always see when I get home.
You have already communicated with one of the founders of Nuki…
Your problem is most likely not related to beta firmware and therefore it is a bit offtopic here.
Nevertheless, please try the following:
- Remove the batteries from the lock
- Remove the lock from the door/mounting plate
- Insert the batteries into the lock. The motor will start and continuously run for ~20s.
- After the motor stopped, take out the batteries and perform step (3) two more times so that the motor did spin in total for ~1min
- Take out the batteries again, put the lock back on the mounting plate, insert the batteries and wait until the lock performed the position run.
Please observe if this did improve the behavior you described and report back your findings.
Batteries do not directly allow to measure their remaining capacity, therefore it can only be measured indirectly by the voltage they have. Not all batteries have the same voltage levels (that’s most likely why your eneloops are not shown as 100%). In addition a defective battery or cold temperatures can lead to situations where the voltage level looks fine, but the batteries still do not perform under load. In general we recommend to use Eneloops or the Nuki Powerpack for highest reliability of the Smart Lock Go (and all older generation models).
Well, I have Nuki Power Pack (Nuki 3 Pro) and have to say it’s really reliable… I have it from about 2 years now… and apart of some isolated issue with “fake” recharge status (which I have reported witout getting any answer/feedback, which is bad) I would reccomend it.

Sweet! Now I can start to play with the Aliro features…
I have just installed the latest Beta Firmware 5.6.5 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.
However, there is one thing I would like to mention. 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?
Today after 9 months my lock died, it looks something inside goes wrong because it doesnt stop rotating… like a broken key but it isn’t. Verry disapointed in this product, im using nuki since nuki 2.0 never had issues like this.
