Let's hope they get to it, otherwise these are not worth buying or suggesting to other people to buy.

  @algorythm have you tried adding tags to this post? It may help with visibility. Specifically the OVINF/RTSP tag

Hello, dear TP-Link Support Team

I would also really appreciate it if you would re-enable the ONVIF/RTSP function on the Tapo C425. I recently purchased a kit with four Tapo C425 cameras and subsequently discovered that the ONVIF/RTSP function is not supported at all, and I cannot integrate and use these cameras in HA as desired. This is very frustrating, and I will opt for a different competitor product in the future.
I hope this function will be re-enabled in a future firmware update, so that the end user can decide for themselves whether they want to use this function or not due to the power consumption and the need to charge the cameras more frequently.
Thank you for your understanding and for considering the many users who want this function enabled...
Kind regards,
voesi
