Hello,

The ONVIF integration of Tapo cameras into a third party systems like Skrypted, Home Assistant and NVRs is one of the main features the product to be purchased. At least I have bought 7 cameras because of this. 
 

Tapo team is well aware there is a problem with the ONVIF motion detection after the latest firmware updates on almost all camera models. The problem is here for months. Some of the most skilled developers from Scrypted and Home Assistant communities are trying to find a workaround but it is impossible because the problem is buried too deep into the buggy firmware release.

I have spend hours to read the post in the community here, an I can see a lot of complaints. Regardless of the problem, the support is always pushing in the direction "disconnect the NVR, we don't support HA" kind of "solutions".
 

Tapo cameras  are listed as ONVIF compatible, but currently they are not! Take the problem seriously, as you have already lost the trust of the customers enough, and a lot of them are ready to switch to different manufacturers.
