This Article Applies To
Tapo D210(US/EU/JP/KP) V1.0
TD21(US/UK) V1.0
Description
Recently, you might have noticed that the Tapo D210 V1 or TD21 V1 doorbell has stopped detecting motion or recording events, except when you are watching the live stream in the Tapo app, where detection and recording work normally.
Troubleshooting Guide
Set the doorbell's detection sensitivity to the maximum level, then run the detection-range test on your doorbell. *We recommend conducting multiple tests to avoid coincidental or inconsistent results. How to test the detection range of Tapo battery camera
If the doorbell cannot detect anything during testing, or if the detection range is noticeably limited—for example, within just 1–2 meters, the issue is likely hardware‑related, specifically with the PIR sensor. In this case, a replacement will be needed. To proceed with the warranty, please contact the retailer or local TP-Link support. Contact Technical Support
For other cases, please contact technical support for further investigation.

@Wayne-TP I have been having these issues and now contacted support for a warranty claim. Do you know the turn around time on responses currently? Also if the TD21 is broken, will they issue a different device in replacement? Many thanks

They really need to issue a response about this issue and mention if they are looking into a fix or something.
