Hi @Tonyaliming,
Greetings from the Roku Community!
We understand you are having a problem setting up your Roku indoor camera since the QR code is not showing up. We're happy to assist you further. Please try to uninstall the Roku smart home app, and re-install back again.
If the problem persists, try using a different phone or tablet to see if that fixes it.
We hope this helps, and keep us posted on what you find out.
Best regards,
John
