I currently use Frigate as an NVR for my outside cameras. I would like something that integrates with that. I really just care that it is fully local. I don’t want a chance of someone on the internet being able to access a camera in my baby’s bedroom.
I too have a tp-link tapo indoor camera with said hacs component. I have set alerts for sound and movement, both work well, it need some tuning tough, like mic sensitivity…
For live video feed I use a webrtc camera from hacs as it has much better latency.
As a child monitor it works really well.
