Notifications are not showing on the Kardena smartwatch

Are WhatsApp messages, texts, calls or other notifications not appearing on your Kardena smartwatch?
In most cases, this happens because of missing permissions or your smartphone’s power-saving settings.

1. Check the connection

First, open the app for your smartwatch and check whether the Kardena smartwatch is shown as connected.

2. Enable notifications in the app

In the app, open the notification settings and enable the desired apps. For example:

• WhatsApp
• SMS / Messages
• Phone
• Email
• Messenger

ℹ️ Note:
The smartwatch can only show notifications that are forwarded to it by the smartphone or the app.

3. Check your smartphone’s permissions

The app requires access to your smartphone’s notifications.
Open your smartphone’s settings and check that notification access is allowed for the app you are using.

4. Check power-saving features

Android smartphones in particular can automatically close apps running in the background.
Therefore, please check that:

• Background activity is allowed
• Battery optimisation is disabled
• Autostart is allowed, if available
• Bluetooth usage in the background is allowed

⚠️ Important for Android:
Names vary depending on the smartphone manufacturer. Samsung, Xiaomi, Huawei, Honor, Oppo, Apple and other manufacturers sometimes use their own power-saving features.

5. Restart your devices

Restart both your smartphone and your smartwatch, then check the connection again.

💡 Tip:
If call notifications work but WhatsApp doesn’t, the problem is most likely caused by notification permissions rather than the Bluetooth connection.
