Reolink Doorbell with two-way audio?! (no issue, just info request)

[pickonedev]

Hi!

Anyone have manage to achieve the two-way audio with a reolink doorbell without problems? If yes, can you please share the code of the card.

Thank you!

I would also be very interested... I tried several configs and didn't get it to work. On top I don't have any sound now from the stream -.- using this atm:

type: custom:webrtc-camera
ui: true
streams:
  - url: rtsp://USER:PW@IP:554/h264Preview_01_sub
    name: 😶
    background: false
    muted: false
    mic: false
    mode: webrtc
  - url: rtsp://USER:PW@IP:554/h264Preview_01_sub
    name: 🎙️
    background: false
    muted: false
    mic: true
    ### media: video,audio,microphone ### or do i need this line?
    mode: webrtc

[daxcore]

Yeah, i guess i got it.

type: custom:webrtc-camera
server: https://go2rtc.example.com/
streams:
  - url: reolink
    mode: webrtc
    media: video,audio
    name: 🔇
  - url: reolink
    mode: webrtc
    media: video,audio,microphone
    name: 🔈
ui: true
muted: false

go2rtc:

streams:
  reolink:
    - rtsp://admin:[email protected]:554/Preview_01_sub
    - "ffmpeg:reolink#audio=opus#audio=volume#async"

ffmpeg:
  bin: ffmpeg
  volume: "-af \"volume=25dB\""

reverse proxy (ofc don't forget the dns entry):

server {
    server_name go2rtc.example.com;

    listen 80;

    if ($scheme = http) {
        return 301 https://$server_name$request_uri;
    }

    ssl_session_timeout 1d;
    ssl_session_cache shared:MozSSL:10m;
    ssl_session_tickets off;
    ssl_certificate /ssl/fullchain.pem;
    ssl_certificate_key /ssl/privkey.pem;

    ssl_dhparam /data/dhparams.pem;

    listen 443 ssl http2;
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

    proxy_buffering off;

    location / {
        proxy_pass http://homeassistant.local:1984;
        proxy_set_header Host $host;
        proxy_redirect http:// https://;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}

@daxcore Hi! Can you please explain what you wrote there, like you would explain it to a noob? :-D I only understand the first code which represents a webrtc-camera card, but what about the next two codes? What are, how, where? :-)

Thank you in advance!

[can-I-do]

If everything else works for you you just need the first part:

type: custom:webrtc-camera
server: https://go2rtc.example.com/
streams:
  - url: reolink
    mode: webrtc
    media: video,audio
    name: 🔇
  - url: reolink
    mode: webrtc
    media: video,audio,microphone
    name: 🔈
ui: true
muted: false

This part should somehow similar already be in your go2rtc.yaml, but not needed if you add the url directly into the card, like I did in my previous post:

streams:
  reolink:
    - rtsp://admin:[email protected]:554/Preview_01_sub
    - "ffmpeg:reolink#audio=opus#audio=volume#async"

ffmpeg:
  bin: ffmpeg
  volume: "-af \"volume=25dB\""

So the trick seems to be this line media: video,audio,microphone, no need for mic: true. The mic is working, evertheless it seems that I don't have any sound coming back -.-

[pickonedev]

Thank you, I will try it today <3

Still... I am asking myself... for this Two-Way thing, why you need two streams? Ok, ok, I understand that one is with microphone and the other is not, but would not be easier if you use only one stream, but you have a button to turn on/off the microphone? Like the speaker... click Mute/click UnMute, could not this microphone have a similar usability?

@AlexxIT ? Is this not possible? Sorry if maybe I transform a "question" post into a "feature request", first I just ask to know more.

Thanks

Edit: Two streams are slower to load, this is why I ask... When you click to unmute the mic, the stream should load again and so on...

Edit2: @can-I-do wow, seems that there is no sound for me as well :)) More than that, the stream it is loading as paused, I need to press play to start, but it won't do nothing, the streams shows a static image from the last frame, but that's it...

[AlexxIT]

Two separate streams is good design because you take and release mic not only on browser, but also on camera

[daxcore]

lets have a look to the readme.md file:

Two-way audio

• Only for supported sources in go2rtc
• Only for Hass with HTTPS access, this limitation is from the browsers
• Only for WebRTC mode
• HTTPS is also important for Hass Mobile App!

You should add microphone to media param. You can use two streams: one with mic, second without:

type: 'custom:webrtc-camera'
streams:
  - url: go2rtc_stream
  - url: go2rtc_stream
    mode: webrtc
    media: video,audio,microphone

for 2-way audio, https is the key. that's why, i posted my nginx reverse proxy configuration. i guess, if the server: https://go2rtc.example.com/ in your card code will not refer to https url, it will not work!

This is what I try to use in my card

type: custom:webrtc-camera
ui: true
muted: false
streams:
  - url: rtsp://admin:[email protected]:554/h264Preview_01_sub
    mode: webrtc
    media: video,audio
    name: 🔇
  - url: rtsp://admin:[email protected]:554/h264Preview_01_sub
    mode: webrtc
    media: video,audio,microphone
    name: 🔈

HA it is configured to use HTTPS only from outside, when I access it from local, it is only with HTTP. I don't need the server line because I am using it from HA.

I use "NGINX Home Assistant SSL proxy" but no special config...

[can-I-do]

after I added this stuff after and before "-->" to my go2rtc.yaml sound seems to work now. Not actually sure if this is related or an accident :D

streams:
  reolink:
    - rtsp://admin:[email protected]:554/Preview_01_sub
    - "ffmpeg:reolink#audio=opus. --> #audio=volume#async" 

ffmpeg:
  bin: ffmpeg
  volume: "-af \"volume=25dB\""
<-- 

[pickonedev]

Where can I find this file go2rtc.yaml ? I don't have it in my HA

[can-I-do]

Where can I find this file go2rtc.yaml ? I don't have it in my HA

should be directly in your config folder, there is also your configuration.yaml and automations.yaml.

[pickonedev]

I search but nothing... There is no file like this

[can-I-do]

Ok, maybe we missed to ask at the very beginning if you have go2rtc installed in your HomeAssistent. If so, you can also create the file and paste the stuff above

[pickonedev]

I have just installed the WEBrtc Camera integration from HACS, nothing else. Should I install any ohter addons?
