Sounds like you’ve gone down all the paths I can help with lol. Mine streams just fine using Frigate in HAOS and using RTSP. The two way audio doesn’t work quite yet but I also haven’t tried too hard to diagnose since the audio otherwise functions, so I’m assuming it’s just a configuration issue.

I also 3D printed a mount I found on Thingiverse since the ones it came with didn’t angle it far enough for my needs.

I guess I should’ve said “on its own dedicated hardware” too but, still.

I think I remember reading somewhere about a firmware update that was pretty recent (8/2025) specifically for latency issues, you might want to check that out if you’ve had it awhile.

Have you thought about moving your HA off your server and onto a miniPC? I know you weren’t really looking for advice but that seems like the move to me tbh, doesn’t take long to migrate and it might clear up a lot of headaches.
