    Homebridge SimpliSafe 3

    Created by Niccolò Zapponi and Michael Shamoon.

    npm-version npm-downloads verified-by-homebridge

    An [unofficial] Homebridge plugin to integrate the SimpliSafe 3 home security system with HomeKit.



    Supercharge your SimpliSafe system and integrate with HomeKit the right way! This plugin supports:

    • Real time event streaming: get immediate notifications anytime the alarm is armed / disarmed / triggered.
    • Sensors: always be on top of your home with immediate access to the sensor status. Create smart automations directly from the Home app (e.g. when the front door is opened, turn the lights on).
    • Door locks: lock, unlock and monitor the battery status of your smart door locks.
    • Cameras: view your indoor or doorbell cameras directly from the Home app, receive doorbell notifications and motion snapshots.
    • Battery monitoring: the Home app will notify you if the battery level of one of your sensors is low.

    Here are some example screenshots:

    This plugin supports installation and changing settings (for config.js) via the popular Config UI X plugin which is recommended for easiest usage.

    Either install and configure using Config UI X or you can manually install the plugin by running:

    npm install -g --unsafe-perm homebridge-simplisafe3

    If installing manually, add the following configuration to the platforms array in your Homebridge config.json and then proceed with authentication.

        "platform": "homebridge-simplisafe3.SimpliSafe 3",
        "name": "Home Alarm"

    SimpliSafe Authentication

    1. Users of Config UI X (which is included in many Homebridge installations) can initiate this process from the plugin settings. A button will launch the authentication process and attempt to automatically obtain a token from SimpliSafe. During the process you will either have to verify via email or enter an SMS vertification code (same as logging into SimpliSafe website). Please check the homebridge logs if errors occur.

    2. Alternatively the plugin provides a command-line method for authenticating. The process works the same as above and can be run using homebridge-simplisafe3 login. If you are using a non-standard storage location for Homebridge pass the -d argument e.g. homebridge-simplisafe3 login -d /path/to/storage/.

    Authentication Failure Notifications

    The plugin is designed to persistently and proactively maintain authentication with SimpliSafe but obviously this is not perfect. When authentication with SimpliSafe fails, the plugin sets the Status Fault property of the Alarm to true. Though you are not able to see this property in the Home app, it can be viewed in other HomeKit apps and you can create automations based on this, for example to send you an email or notification when this happens using the excellent homebridge-messenger plugin. For more details on an example notification setup see this discussion.

    Optional Parameters

    cameras and cameraOptions

    These enable camera support. See Camera Support for more details.


    Type: boolean (default false)

    Switch this on to get more details about your sensors and plugin behavior in your Homebridge logs. This can be useful if you are having trouble or need to report an issue.

    subscriptionId (aka Account Number)

    Type: string

    Add this parameter in case you have multiple protected locations or accounts with SimpliSafe, this is your "account number" in Simplisafe. The best way to ensure you have the correct number is to check under the SimpliSafe web control panel > View Account and look for account # next to the correct plan. For most users this is the same as the serial number at the bottom of your base unit.


    Type: integer (default 15 seconds)

    The frequency with which the plugin will poll sensors (e.g. Entry sensors), since entry sensor changes (opening/closing) are not pushed from SimpliSafe. Warning: setting this value too low will likely lead to your IP address being (temporarily) blocked by SimpliSafe.


    Type: boolean (default true)

    By default, the plugin will persist accessories to avoid losing automations etc. Set this to false to remove old accessories that no longer exist in SimpliSafe from HomeKit.


    Type: array

    Accepts a list of SimpliSafe device serial numbers (which can be found in the SS app) and excludes these devices from HomeKit.

    Supported Devices

    Device Supported Notes
    Alarm Arming/disarming to home, away and off modes. Sets tamper property on power outage
    SimpliCam Audio, video, motion*, no microphone
    Doorbell Audio, video, motion, no microphone
    Outdoor Camera Not supported yet, see #240
    Smart lock Fully supports locking, unlocking
    Entry sensor Status not provided as 'push' by SS so is polled based on sensorRefresh
    Smoke detector Includes support for tamper & fault
    CO detector Includes support for tamper & fault
    Water sensor
    Freeze sensor Supports temperature readings, not sensor trigger
    Motion sensor Requires motion sensor set to "Secret Alert" or "Alarm" in SimpliSafe settings**
    Glassbreak sensor State not provided by SimpliSafe
    Keypad State not provided by SimpliSafe
    Panic button State not provided by SimpliSafe

    * SimpliCams provide motion notifications only if the privacy shutter is open.

    ** The default SimpliSafe settings for motion sensors are "Disabled" when alarm is "Off" or "Home", in which case motion events will not be accurate since they won't always trigger. For consistency of the Home app, motion sensors need to be switched to either "Secret Alert" or "Alarm" in every alarm mode for the sensors to appear in the app. For example, setting the motion sensor to Secret Alert in Off and Home mode and Alarm in Away mode will display it in the Home app, whereas setting it to Disabled in Off mode, Secret Alert in Home mode and Alarm in Away mode won't, since the sensor state and automations in the Home app would be inaccurate. Using the "Secret Alert" setting will allow for motion events at all times but note that this will also record a video clip when motion events are triggered.

    All devices also support low battery warnings.

    Camera Support

    To enable camera support, simply switch "cameras": true in your config.json (or set via Config UI X admin). Currently only the SimpliCam and Video Doorbell Pro are supported.

    Camera Options

    This plugin includes ffmpeg-for-homebridge to automatically include a compatible build of ffmpeg and thus the plugin works "out of the box" without requiring a custom ffmpeg build.

    For advanced scenarios including specifying a custom ffmpeg build or command line arguments, you can set them via plugin settings in Config UI X or manually in config.json*:

    "cameraOptions": {
        "ffmpegPath": "/path/to/custom/ffmpeg",
        "sourceOptions": "-format: flv ... (any other ffmpeg argument)",
        "videoOptions": "-vcodec h264_omx -tune false ... (any other ffmpeg argument)",
        "audioOptions": "-ar 256k ... (any other ffmpeg argument)"

    Any arguments provided in sourceOptions, videoOptions and audioOptions will be added to the list of arguments passed to ffmpeg, or will replace the default ones if these already exist. To add an argument that requires no additional parameter, e.g. -re, then add it as "-re". To remove a default argument, define it with false as its value, e.g. "-tune false".

    FFMPEG Hardware Acceleration

    The bundled build of ffmpeg includes hardware acceleration on supported Raspberry Pi models but in order to enable this you must check the setting Advanced Camera Settings > Enable Hardware Acceleration for Raspberry Pi (or set "enableHwaccelRpi" under "cameraOptions" to true in config.json).

    Note that enabling this option assumes you are using the bundled version of ffmpeg and thus may not work if you specify a custom one.

    Known Issues

    • If you are running Homebridge oznu/docker-homebridge camera streaming is limited to 720px wide.
    • Due to transcoding requirements, when using a Raspberry Pi 3b video feeds will disconnect after ~20 seconds. RPi 4 or newer is recommended. See issue #147
