Troubleshooting Tapo D210/TD21 Won't Wake Up Unless Watching Liveview in the Tapo App
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.

@JayTipper @Kazbop @MrChuter Mine has now gone back under RMA. Still don't think it is a hardware issue (unless it is a batch problem) but will keep you all posted what happens next...

As mentioned in this thread, if your doorbell behaves normally during the detection range test, then Contact Technical Support for further assistance.

Just had my replacement come back from TP Link.
Tech Support have been great at organising this, although it did take over 2 weeks to turnaround.
So far no issues and the product works properly this time, even when the app is backgrounded. I have yet to do any firmware updates - and probably wont do!
