FAQ

Q: Why is there no audio?

A: Audio is not supported at this time. For more info, please read this issue.

Q: The video thumbnail is not updating.

A: This is a HomeKit issue and not a Homebridge issue. Rebooting your phone usually fixes it.

Installation

1. Install ffmpeg
2. Install this plugin using: npm install -g homebridge-nest-cam2
3. Add google authentication to config.json
4. Run Homebridge
5. Add extra camera accessories in Home app using the same setup code as Homebridge

On Raspberry Pi you might want to use OMX for transcoding as CPU on the board is too slow. In that case, make sure the ffmpeg you installed has h264_omx support and set ffmpegCodec above to h264_omx. There are pre-compiled deb online if you don't want to compile one yourself.

On MacOS you might want to use VideoToolbox hardware acceleration for transcoding. In that case, make sure the ffmpeg you installed has videotoolbox support and set ffmpegCodec to h264_videotoolbox.

Setting up the Config.json

Setting up a Google Account with homebridge-nest is a pain, but only needs to be done once, as long as you don't log out of your Google Account.

Google Accounts are configured using the "googleAuth" object in config.json, which contains three fields, "issueToken", "cookies" and "apiKey", and looks like this:

{
    "platform": "Nest-cam",
    "ffmpegCodec": "libx264",
    "googleAuth": {
        "issueToken": "https://accounts.google.com/o/oauth2/iframerpc?action=issueToken...",
        "cookies": "SMSV=ADHTe...",
        "apiKey": "AIzaS..."
    }
}

The values of "issueToken", "cookies" and "apiKey" are specific to your Google Account. To get them, follow these steps (only needs to be done once, as long as you stay logged into your Google Account).

1. Open a Chrome browser tab in Incognito Mode (or clear your cache).
2. Open Developer Tools (View/Developer/Developer Tools).
3. Click on 'Network' tab. Make sure 'Preserve Log' is checked.
4. In the 'Filter' box, enter issueToken
5. Go to home.nest.com, and click 'Sign in with Google'. Log into your account.
6. One network call (beginning with iframerpc) will appear in the Dev Tools window. Click on it.
7. In the Headers tab, under General, copy the entire Request URL (beginning with https://accounts.google.com, ending with nest.com). This is your "issueToken" in config.json.
8. In the 'Filter' box, enter oauth2/iframe
9. Several network calls will appear in the Dev Tools window. Click on the last iframe call.
10. In the Headers tab, under Request Headers, copy the entire cookie (beginning SMSV=... - include the whole string which is several lines long and has many field/value pairs - do not include the cookie: name). This is your "cookies" in config.json.
11. In the 'Filter' box, enter issue_jwt
12. Click on the last issue_jwt call.
13. In the Headers tab, under Request Headers, copy the entire x-goog-api-key (do not include the x-goog-api-key: name). This is your "apiKey" in config.json.

Run Homebridge using Docker

If you are having issues with this plugin, you may want to try running Homebridge inside a docker container. This ensures that you are using the most up-to-date resources and that no external programs are interfering with the plugin. Just follow the instructions here to install homebridge using docker and add PACKAGES=ffmpeg to the environment section.
