    The Homebridge SwitchBot plugin allows you to access your SwitchBot Device(s) from HomeKit with Homebridge.

    1. Search for "SwitchBot" on the plugin screen of Homebridge Config UI X
    2. Find: @switchbot/homebridge-switchbot
      • See noble prerequisites for your OS. (This is used for BLE connection.)
    3. Click Install

    You can now configure global OpenAPI polling and rate-limiting options directly from the Homebridge UI:

    • Go to the SwitchBot plugin settings in Homebridge Config UI X.
    • Scroll to the Advanced Settings section at the bottom of the page.
    • Adjust the following options as needed:
      • OpenAPI Polling Interval (seconds): How often to poll devices via OpenAPI for status. Default: 300 (5 min). Min: 30. Can be overridden per device.
      • Enable Batched OpenAPI Polling: Poll all OpenAPI devices in a single batch at the configured interval. Devices with per-device refreshRate are excluded from the batch.
      • OpenAPI Batch Polling Interval (seconds): Interval for batched OpenAPI polling. Falls back to OpenAPI Polling Interval if not set. Default: 300.
      • OpenAPI Daily Request Limit: Maximum OpenAPI requests per day allowed by the plugin. Default: 10000.
      • OpenAPI Reserve for Commands: Requests reserved for user actions. When remaining budget reaches this value, background polling pauses. Default: 1000.
      • Reset OpenAPI Counter at Local Midnight: If true, resets the daily OpenAPI request counter at local midnight. If false, resets at UTC midnight.
      • Only Allow Webhooks on Reserve: When remaining OpenAPI budget reaches the reserve, only webhooks and user commands are allowed. Background polling/discovery pauses.
      • OpenAPI Batch Concurrency: Maximum number of parallel OpenAPI status calls during a batch. Default: 5.
      • OpenAPI Batch Jitter (seconds): Random startup delay before the first batch to reduce synchronized spikes. Default: 0.

    Click Save Advanced Settings to apply changes. These settings match the options available in config.schema.json and can be overridden per device.

      6. Input your secret into the config parameter
      1. Download SwitchBot App on App Store or Google Play Store
      2. Register a SwitchBot account and log in into your account
      3. Click on Device wanting to connect too plugin
        • Click the Settings Gear
        • Click Device Info
        • Copy BLE Mac aka deviceId
      4. Input your deviceId into the Device Config

      1. bluetoothctl must be installed on the device, otherwise it cannot communicate via Bluetooth. Enable it with sudo bluetoothctl power on.

      2. If errors occur, while enabling it, restart the process:

        • rfkill block bluetooth
        • rfkill unblock bluetooth

      3. Also make sure, that the computer can discover the SwitchBot device:

        • sudo bluetoothctl
        • scan on

        This lists all discovered Bluetooth devices. The BLE address of the SwitchBot device should be included in this list, otherwise your computer does not discover it.

      1. Manually grant Bluetooth access in System Settings UI for Security & Privacy -> Privacy to the node executable, eg /usr/local/bin/node Security & Privacy -> Privacy (This is what is intended in documentation for the noble bluetooth package prerequisites by "Add terminal app", however for HomeBridge it is node that needs the permission granted, not terminal. Without this step, then you will receive the following error when the swichbot plugin launches, which will cause Homebridge or the child bridge process to restart:
      Error: Failed to initialize the Noble object: unauthorized

    Some SwitchBot devices (notably newer locks, curtains, and select sensors) require a BLE encryption key and keyId for secure Bluetooth communication. This plugin supports configuring these fields for each device.

    1. Open the SwitchBot App and select your device.
    2. Go to Device Settings (gear icon).
    3. Tap Device Info.
    4. If your device supports BLE encryption, you will see fields for Encryption Key and Key ID. (If not visible, your device may not require encryption or may need a firmware update.)
    5. Copy the Encryption Key and Key ID values.

    In the Homebridge UI, when adding or editing a SwitchBot device, enter the Encryption Key and Key ID in the provided fields. These values will be securely used for BLE communication with your device.

    Example device config excerpt:

    {
      "deviceId": "E7F8A1B2C3D4",
      "deviceName": "SwitchBot Lock",
      "enableBLE": true,
      "encryptionKey": "0123456789abcdef0123456789abcdef",
      "keyId": "01"
    }
    • SwitchBot Lock (and Lock Pro)
    • SwitchBot Curtain 3 (and some Curtain 2 with updated firmware)
    • Some sensors and new device models (see device info in app)

    If you are unsure, check your device's info in the SwitchBot app. If the fields are present, copy them into the plugin config.

    Note: If you enter an incorrect key or keyId, BLE communication will fail for that device. Double-check values if you encounter connection issues.

    By default, the Matter platform uses a single batched refresh to update device status. You can tune or override this behavior with the following options under options:

    • matterBatchEnabled (boolean, default true): enable/disable platform-level batched refresh. Devices with a per-device refreshRate still run their own timers.
    • matterBatchRefreshRate (number, seconds): batch interval (falls back to options.refreshRate, then 300 if not set).
    • matterBatchConcurrency (number): limit of parallel OpenAPI status calls during a batch (default 5).
    • matterBatchJitter (number, seconds): random startup delay before the first batch to reduce synchronized spikes.

    Device-level override:

    • If a device sets refreshRate in its config, it uses a per-device timer and is excluded from the platform batch.

    Reliability and rate-limiting:

    • Each device status call retries with exponential backoff on non-success responses.
    • After exhausting retries, the device enters a short cooldown before being retried; cooldowns are persisted across restarts.
    • The batch worklist is randomized every cycle to further distribute API load.

    These controls keep API usage smooth and predictable while preserving per-device control when needed.

    • Matter-first: when Homebridge Matter is available the plugin now prefers registering Matter accessories (with HAP fallback).

    • Hybrid client: the plugin uses node-switchbot@^4.0.0 with BLE + OpenAPI discovery and OpenAPI fallback.

    • OpenAPI credentials: cloud discovery and cloud fallback paths require both openApiToken and openApiSecret.

    • UI always served: the plugin UI is packaged into dist/homebridge-ui and is always served when Homebridge UI support is present; there is no platform-level opt-out.

    • OpenAPI hardening: OpenAPI calls have AbortController timeouts, jittered exponential backoff, per-device retry limits and cooldowns, and safe response parsing for resilient behavior.

    • v4 resilience enabled in discovery: plugin discovery enables retry, circuit-breaker, and connection-intelligence flags from node-switchbot v4.

    • Write coalescing (debounce): command writes to the same device are coalesced by default to avoid command floods. Configure with writeDebounceMs (milliseconds, default 100). Set to 0 to disable coalescing.

    See MIGRATION.md for migration notes and recommended upgrade steps.

    To prevent hitting SwitchBot’s daily OpenAPI limit, the plugin provides several platform-level options under options:

    • dailyApiLimit (number, default 10000): maximum OpenAPI requests per day that the plugin will allow.
    • dailyApiReserveForCommands (number, default 1000): requests reserved for user actions so background polling pauses before the hard limit.
    • webhookOnlyOnReserve (boolean, default false): when remaining budget reaches the reserve, pause background polling/discovery; webhooks and commands continue until the hard limit.
    • dailyApiResetLocalMidnight (boolean, default false): if true, resets the daily counter at local midnight; when false, resets at UTC midnight.

    Example (excerpt):

    {
      "options": {
        "dailyApiLimit": 10000,
        "dailyApiReserveForCommands": 1000,
        "webhookOnlyOnReserve": false,
        "dailyApiResetLocalMidnight": true
      }
    }

    • Run unit tests:

      npm run test

    • Notes:

      • Added Lock Ultra (Cloud + BLE) support with node-switchbot v4.
