If the Tapo D210 detects people but your phone does not alert you, these checks come from Tapo’s notifications guide. The same doorbell is also sold as the Tapo TD21, so these steps work for both.

What This Problem Means

Events are recorded but the alerts are not reaching your phone, or arrive late.

Common Symptoms

• No alerts on your phone
• Alerts arrive minutes late
• Clips are in the app but you were not told

Safe Checks You Can Try

1. Turn notifications on in Tapo

Tapo’s notifications guide says to turn on notifications in the Tapo app and, while testing, set the Notification Schedule to Always.

2. On an iPhone

Go to Settings > Notifications > Tapo: allow notifications and set Show Previews to Always. Turn off Do Not Disturb or Focus.

3. On Android

Go to Settings > Notifications > App notifications and turn Tapo on. Turn off Do not disturb, and update the phone’s software and Google Play services.

4. Stop Android delaying them

Tapo says to allow Tapo to autostart, turn off battery optimisation for it and lock it in recent apps. On Samsung phones, add Tapo to Never sleeping apps.

5. Reboot the doorbell

Tapo suggests rebooting the doorbell if alerts are still delayed.

6. Know how ring calls work

Tapo says doorbell ring calls follow the same schedule as activity notifications.

When To Contact Support

If none of these checks fix it, contact Tapo support through TP-Link’s UK support site. Have the model and hardware version ready: Tapo says both are on the label on the doorbell.

Last resort: factory reset. Check the installation guide for where the Reset button is on the Tapo D210; Tapo’s reset guide covers its cameras. You will then need to set it up again in the Tapo app. Removing it in the app (long-press its card, or Camera Settings > Remove) also resets it; Tapo says a Tapo Care plan stays on your account.
