2-way audio with POE Reolink Doorbell

Hello everyone

I apologize, I know this topic has already been discussed several times.

I use the D340 POE doorbell from Reolink. I was able to successfully integrate with the Reolink and the Onvif integration in to HA. Unfortunately it does not work with the 2 way audio.

My configuration.yml:

# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder

My go2rtc.yml:

streams:
  camera.reolink_doorbell_1:
  - rtsp://USER:[email protected]/Preview_01_main
  - ffmpeg:192.168.9.11#audio=opus#audio=copy

My lovelace card:

type: custom:webrtc-camera
streams:
  - entity: camera.reolink_doorbell_1_profile000_mainstream
    mode: webrtc
    media: audio,video,microphone

I use NGINX as a reverse proxy and there I forward https://homeassistant.MY-DOMAIN to http://IP:8123.

It is strange that the option “video+audio+microphone” is not active under WebRTC Magic.

I am also a bit confused, the first stream comes from the go2rtc configuration and the second from the lovelace card.

I tested it on my notebook (Chrome and Edge browser) and also on my Google Pixel with the HA app. I can hear what someone says through the camera. But unfortunately my answer doesn’t come back.

Can anyone tell me what I am doing wrong?

Thanks and best regards
Buhli
