If you aren’t able to scan the QR code, you can still try these options with the new app:
- Use the S2 secure pairing method as described here with the Generic Z-Wave option, when it gets to the QR code, it’ll give you an option to enter the DSK key manually instead of scanning it (this is only available using the latest ST app and the Generic Z-Wave option).
- Use the Scan nearby option when adding a device in the ST app, this will pair using S0 (which shoudn’t matter for most devices but some devices like the Ring keypad are finicky about it)
