Hello,

Thank you for your detailed post, and welcome to the community.

First, we’d like to clarify an important point: there is no functional difference in how the Tapo C520WS V1 and V2 report events to Alexa. Under normal conditions, both hardware versions should expose event information to Alexa in a consistent manner.

To help us better understand the root cause, we kindly ask you to confirm and assist with the following:

1. Alexa routines and settings
Please provide the details of your routines and review the Alexa routines and notification settings associated with each camera. We’d like to confirm whether any routines may be overlapping or reacting to multiple event types, which could result in duplicate announcements.

2. Tapo app notification behavior
Could you please check whether the Tapo app itself only receives a single person‑detection notification for the same event? This will help determine whether the duplication originates from the camera/app side or specifically within Alexa’s handling

3.  If convenient, please help collect:

• The original person‑detection video clip as shown in the Tapo app
• A short video recording capturing the Alexa voice announcements occurring for that same event
  These materials will help us correlate the event timing and behavior. 

Once we have this information, we’ll be in a better position to evaluate whether this is related to a configuration interaction, an Alexa routine behavior,

Best Regards

Hi,

Thank you for your prompt response. Please find the requested information below:

1. Alexa Routines and Settings
I do have other routines configured (e.g., for switching on outdoor lights). However, for person detection, I am currently using the default Alexa notification method.
Screenshots of all relevant settings have been included in the attached ZIP file.

2. Tapo App Notification Behaviour
Upon reviewing the event logs in the Tapo app, only a single person detection event is recorded.

Screenshots of the events have been included in the attached ZIP file

3. Additional Information Provided
I have uploaded both audio clips to the ZIP file:

• V1 camera: two notifications
• V2 camera: one notification

It can also be noted that the duplicate notification from the V1 camera differs slightly in audio, indicating they are being triggered separately.

Findings
If the cameras are removed from the “Camera Events” settings page and only the “Person Detection Announcements” toggle is enabled (on the main page), the V1 cameras announce only once on Alexa. However, in this configuration, the V2 camera does not generate any announcements.

Removed the ZIP File - due to solution below

Hi,

I did some testing again and found a solution. Previously, I had tried unlinking Tapo and Alexa multiple times without success.

The only change I noticed was that I had added the C520WS V2 after initially installing the C520WS V1 cameras last year.

 

Here’s what worked: I completely removed a C520WS V1 camera from Alexa and then unlinked Tapo and Alexa. When Alexa re-discovered the C520WS V1 camera, it started behaving like the C520WS V2—announcing events only once. I repeated this process for all the V1 cameras, and now everything is working 100%.

 

I believe there were some changes late last year in how Alexa and Tapo exchange camera events, hence the additional "Camera Events" tab. For some reason, the V1 cameras didn’t accept these changes automatically—they had to be completely deleted and re-discovered.
