Step by step

  1. 1 min

    Verify Thread-compatible hardware

    Ensure your intended Border Router is a Thread-certified device such as a HomePod, Apple TV 4K (Ethernet model), or a dedicated smart home hub. Confirm the device is powered on and connected to the same local network as your mobile control device.

    Note: Thread border routers require an active connection to your home router via Wi-Fi or Ethernet.

    Prepare the Home app

    Open the Home app on your iPhone or iPad. Ensure you are signed in with the same iCloud account intended for managing your smart home accessories to maintain network consistency.

    Note: Disable VPNs on your mobile device during the setup process to prevent discovery errors.

    Add the Border Router

    Tap the plus (+) icon in the top right corner of the Home app and select Add Accessory. Scan the setup code located on your Border Router device or enter the eight-digit code manually.

    Note: If adding a HomePod or Apple TV, it may be automatically detected if it is already associated with your Apple ID.

    Assign the device to a room

    Follow the on-screen prompts to name your Border Router and assign it to a specific room within the Home app. This organizational step helps the controller manage mesh routing paths more efficiently.

    Pair Thread-enabled accessories

    Initiate the pairing process for your Thread-capable smart accessory (such as a light bulb or sensor). The Border Router will automatically detect the device and negotiate a connection over the Thread network instead of Bluetooth or Wi-Fi.

    Note: Look for the Thread logo on the product packaging to confirm the device supports the protocol.

    Confirm connection status

    Navigate to the accessory settings in the Home app. Under the Status section, check that the connection type lists Thread. If the connection type is absent or shows Bluetooth, power cycle the accessory to force a renegotiation with the Border Router.

    Note: Thread networks self-heal; allow the network 60 seconds to stabilize after adding multiple devices.
