Hi Simon.
I'm having trouble finding the Setup ID for my device. In the FAQ part "How do I find out the setup id of my HomeKit Accessory?" you write "Scan the QR code with a QR scanner of your choice.".

Which QR code do you mean?

In my case I have an "old" Fibaro single switch with a HomeKit setup code (8 digits). My QR scanner result is: x-hm://0086412S4 (only 9 characters)

This is my generate command: npx homekit-code qrcode --category=switch --pairingCode=XXXXXXXX --flag=4

Kind regards
Mathias
