• Dedicated Matter tab for discovering smart home devices with vendor lookup, device type, commissioning mode, and discriminator
• Dedicated Bluetooth tab scans for nearby Matter commissioning devices via BLE (service UUID 0xFFF6)
• Export discovered services as plain text or JSON for sharing and documentation
• Search across service names, types, and TXT record values to find what you're looking for instantly
