Release Notes: Nuki Smart Lock 5.9.4

We are excited to announce the latest firmware update for the Smart Lock Pro, Ultra and Go. Here's what you'll find in this release:

  • To ensure the long-term health of the battery in your Smart Lock Pro (5th Gen.) and Ultra, we have added a charge limit. By default, your device will charge up to 80 %. You can adjust this setting by tapping the Smart Lock's “Settings“ → “Features & Configuration“ → “Battery“. 
  • Minor changes and improvements in the background ensure that the Smart Lock runs even more smoothly.

Enjoy using your Smart Lock with the improved firmware.
