Source: Nest - "400 Bad Request"

[Lockie85]

Hey,

I'm trying to get my nest camera working on Version: 1.9.1 via the following method:

streams:
  nest-doorbell: nest:?client_id=***&client_secret=***&refresh_token=***&project_id=***&device_id=***

However, I'm getting "400 Bad Request".

I've checked my:
client_id
client_secret
refresh_token
project_id
device_id

All are correct and I've confirmed this via commands like:

curl -X GET \
  'https://smartdevicemanagement.googleapis.com/v1/enterprises/YOUR_PROJECT_ID/devices/YOUR_DEVICE_ID' \
  -H 'Authorization: Bearer YOUR_ACCESS_TOKEN' \
  -H 'Content-Type: application/json'

Which provided a successful response. I'll keep checking as maybe I've made and missed a tiny mistake somewhere, but assuming I've not, any ideas what might be going on? Many Thanks.

Also worth noting that when I try entering details the camera via the "Add" > "Goggle Nest" UI, I get "no sources".

go2rtc v1.9.0 had a bug where consumer connections where not closed.
It drained my nest doorbell battery.
Have you checked it works on the Google Home app?
v1.9.1 solved it for me.

go2rtc v1.9.0 had a bug where consumer connections where not closed. It drained my nest doorbell battery. Have you checked it works on the Google Home app? v1.9.1 solved it for me.

On version 1.9.1, I still get "400 Bad Request". Is there a good method of debugging this problem?

I've set the log level to debug and here is what I'm seeing:

5/11/2024, 10:08:58 AM | debug | [webrtc] new consumer src=nest-doorbell
5/11/2024, 10:09:00 AM | debug | [mp4] add consumer error=streams: nest: wrong status: 400 Bad Request

Sorry for repeating myself but are you sure it works on the home app?

Is there a good method of debugging this problem?

I would try to make it work using Home Assistant first with the nest integration, then copy the exact credentials from ha (/config/.storage/core.config_entries if I remember correctly. Just search for the nest client id in the .storage folder and the relevant json will show up) including the exact same refresh token.

I don't have Nest cameras, so can't help with that

Ive got the same issue (nest doorbell wired), and I've triple checked my params:

• client_id
• client_secret
• refresh_token
• project_id
• device_id

Ive also made the API request to fetch the device with the access token and deviceId as per the original post here, and I get a good response back. Im using go2rtc 1.9.2 and Frigate (0.13.2-6476f8a)

        "sdm.devices.traits.CameraLiveStream": {
          "maxVideoResolution": {
            "width": 640,
            "height": 480
          },
          "videoCodecs": [
            "H264"
          ],
          "audioCodecs": [
            "AAC"
          ],
          "supportedProtocols": [
            "RTSP"
          ]
        },

But get this in Frigate go2rtc log

Eventually it gets throttled, HTTP 429.

I manage to get this working with HA Google Nest addon though.

I think maybe this is because Nest doorbell wired (legacy) only supports RTSP stream, and go2rtc only support Nest with webRTC stream?
