Smart Lock 3.0 Beta 3.8.1

  • Bugfixes and stability improvements

Dear Stefan,
how can I install a beta version of the firmware (my NUKI smart lock does not work with home assistant via Matt any more (since 2 days)). Maybe the new firmware solve the issues.
Thank you in advance for your reply.
Best regards Walter (Austria)

Other 2 things (one good, one bad) about 3.8.1 Beta

  1. the automatic Battery detection type now works (wrt Power Pack of Nuki 3 Pro)

  2. create battery report now doesn’t work anymore (it remains on “create report” forever)

Can someone else confirm?


No, but it took a longer time than before to create the report and bring me to the assistant which ask for type of battery to confirm all is find.
Now it takes more than a minute to display next step when it was less than a minute before.

OK… I didn’t wait so long as before it was much faster…

Do you use the iOS or Android App?

I use the Android App.

It takes 75sec in my iOS App to get the battery report. Never tried it before so I can‘t compare to earlier than 3.8.1

Before it was few seconds to start
