Commission a Matter device into a home network using a mobile controller and Thread or Wi-Fi transport

Steps

1. Ensure the Matter controller app (e.g., Apple Home, Google Home, Samsung SmartThings) is up to date; for Thread devices, verify a Thread Border Router is present and connected to the same network as the controller
2. Locate the device's QR code or 11-digit manual setup code on the device packaging or label; the QR code encodes a discriminator and PASE passcode used to establish the initial secure channel
3. In the controller app, select 'Add device' and scan the QR code or enter the manual setup code; the controller opens a Bluetooth LE (BLE) channel to the device and runs PASE (Password-Authenticated Session Establishment) using the passcode
4. After PASE, the controller commissions the device by installing an operational certificate (NOC) signed by the controller's fabric CA and configures network credentials (Wi-Fi password or Thread network key) so the device can join the IP network
5. The device joins the IP network, completes operational discovery via mDNS or DNS-SD, and becomes accessible to the fabric; the controller can then add the device to rooms, assign automations, and share it with other fabrics via multi-admin
6. To add the device to a second fabric (e.g., both Apple Home and Google Home), use the controller's 'Share device' or 'Add to another platform' flow which opens a new commissioning window without removing the first fabric
