Features

• Live view — IMMI and RTSP streaming via ffmpeg with automatic keepalive (H.264 video, AAC-ELD audio on IMMI cameras)
• Security system — Arm/disarm per network, with optional manual arm switch
• Multi-network — Supports multiple sync modules, each with independent arm/disarm
• Motion detection — Configurable polling interval with debounce
• Motion enable/disable — Per-camera switch to turn motion detection on or off
• Snapshots — Periodic thumbnail refresh with caching and retry
• Battery — Battery level and low-battery alerts (Outdoor/Indoor models)
• Temperature — Ambient temperature sensor (Outdoor/Indoor models)
• Doorbell press — Push notifications on doorbell button press
• Privacy mode — Per-camera switch to suppress snapshots when disarmed
• Night vision — IR illuminator toggle (Outdoor/Indoor models)
• Clip recording — Trigger a clip recording via momentary switch
• Live View clip saving — Configurable per-network lv_save toggle to save or suppress Live View clips
• One-way audio — Listen-in on IMMI cameras (Mini, Mini 2, Outdoor/Indoor, Doorbell, Floodlight) transcoded to AAC-ELD for HomeKit
• OAuth 2.0 + PKCE — Token refresh and persistent sessions across restarts
• 2FA — One-time PIN verification for Blink's two-factor auth
• Snapshot fallback — Streams the last thumbnail when live view is unavailable
• Stale accessory cleanup — Removes devices no longer on your Blink account
• Retry with backoff — Automatic retry on network errors and rate limiting

Installation

Install Homebridge, add it to Apple Home, then install and configure Homebridge Blink Security.

Recommended

1. Open the Homebridge UI.

2. Open the Plugins tab, search for homebridge-blink-security, and install the plugin.

3. Configure your Blink credentials through the settings panel.

Manual

1. Install the plugin using NPM:

   npm i -g @jackietreeh0rn/homebridge-blink-security

2. Configure the BlinkSecurity platform in ~/.homebridge/config.json as shown in config.example.json.

3. Start Homebridge:

   homebridge -D

2FA Setup

Blink requires two-factor authentication on first login:

1. Configure your username and password and restart Homebridge
2. Blink will send a verification code to your email/phone
3. Add the code to the pin field in config and restart Homebridge
4. After successful verification, remove the pin field — the session is persisted

Development

Prerequisites

• Node.js 18.20.4+, 20.18.0+, 22.10.0+, or 24.0.0+
• Homebridge 1.8.0+ or 2.0.0-beta+

FFmpeg is bundled via the ffmpeg-for-homebridge dependency — no separate install is needed, and it ships with libfdk_aac enabled for AAC-ELD audio.

Setup

npm install
npm run build
npm link

Watch Mode

Automatically recompiles and restarts Homebridge on source changes:

npm run watch

This runs a local Homebridge instance in debug mode using the config at ./test/hbConfig/. Stop any other Homebridge instances first to avoid port conflicts. The watch behavior can be adjusted in nodemon.json.

Linting & Formatting

npm run lint        # check for lint errors
npm run lint:fix    # auto-fix lint errors
npm run prettier    # check formatting
npm run format      # auto-fix formatting

Commits must follow Conventional Commits — enforced by pre-commit hooks via commitlint and husky.

Troubleshooting

No Audio in Live View

One-way audio is supported on IMMI cameras (Mini, Mini 2, Outdoor/Indoor, Doorbell, Wired Floodlight). XT / XT2 cameras use RTSP and are video-only.

Audio is opt-in. To enable it:

1. Set enable-audio: true in plugin config
2. Open the Blink app → Device Settings → Privacy → enable Audio Streaming for each camera
3. Restart the child bridge

If Audio Streaming is disabled in the Blink app, the camera sends malformed audio metadata that stalls the stream. That is why audio defaults to off.

Live View shows "Not responding"

If Live View spins and eventually shows "Not responding" in the Home app, the most common cause is audio being enabled in plugin config while Audio Streaming is disabled in the Blink app for that camera. Either enable Audio Streaming in the Blink app, or set enable-audio: false in plugin config.

VPN Interference

Blink's authentication servers may reject login requests made through a VPN, returning HTTP 406 with no 2FA code sent. If you're unable to complete initial setup:

1. Disconnect your VPN
2. Restart the Homebridge child bridge
3. Complete 2FA verification
4. You can re-enable your VPN after authentication succeeds — sessions are persisted

General

If you run into issues, check the Homebridge troubleshooting wiki first. If the problem persists, open an issue with as much detail as possible.
