Step by step

  1. 2 min

    Perform a local network scan

    Download a network utility application to identify every active IP address on your local network. Run a scan to reveal hardware names, manufacturers, and MAC addresses associated with your IoT devices.

    Note: Filter results by device type to isolate smart home hardware from personal computers and phones.
  2. 3 min

    Define your inventory schema

    Create a spreadsheet with columns for Device Name, Room Location, Manufacturer, Model Number, IP Address, and MAC Address. Add a column for the associated bridge or hub to identify dependency chains.

    Note: Use consistent naming conventions like Room-DeviceType-Manufacturer to ensure easy searching.

    Catalog physical devices

    Physically walk through each room and record the serial number and model information from the device chassis. Cross-reference these details with the entries captured in your network scan.

    Note: If a device is inaccessible, use the manufacturer app's device settings page to retrieve the serial number.

    Log ecosystem dependencies

    Identify which platform each device is integrated into, such as Apple Home, Amazon Alexa, or Google Home. Record the primary management app used for initial setup and firmware updates for every device.

    Note: Maintain a secure list of login credentials separately from this inventory spreadsheet.
  5. 5 min

    Record static IP assignments

    Navigate to your router's administrative dashboard via a web browser using the default gateway IP. Identify any devices currently assigned a static IP or DHCP reservation and update your inventory sheet accordingly.

    Note: Static IPs are critical for hubs and bridges to prevent connection drops after power cycles.

    Archive the master inventory

    Export the spreadsheet to an encrypted cloud storage service or a local hardware wallet. Ensure you have a read-only offline copy stored in a secure physical location.

    Note: Update this document whenever you add or remove a device to maintain total network awareness.
