Nuki will inform you in several ways if the batteries of your Smart Lock are running low.
1. Nuki App
As soon as the battery status of your Nuki Smart Lock drops below 20%, you will receive a notification in the Nuki app. You can find the notification by tapping on the bell symbol at the top right.
2. A blinking Smart Lock
The battery level is not only shown in the Nuki app but also directly on the Smart Lock by a LED signalization on the rotating ring.
3. Push notification
You can additionally receive push notifications informing you when the battery level drops below 20%. In the Nuki app, you will find the option "Manage notifications" in the "Feature & Configuration" section. Here, you can log in with your Nuki Web account. This is essential, as notifications will then be transmitted through your Nuki Web account. You can activate Nuki Web in just a few steps.
4. Email notification
If you use a Nuki Web Account, there is also the possibility to get notified by email when the battery level of your Smart Lock has dropped to a critical level. To use this feature, simply log into your Nuki Web Account and activate the feature "Battery alerts via Email" in the administration of your Smart Lock. You will be notified by email when it is time to change your batteries.
