Storing Smart Home Codes

I store a lot in 1password to keep everything together.

I am starting to get into Smart Home and devices.

Most come with a code or a QR Code. Depending on where you put the device,
It may not be convenient to access the code if I need to re-pair the device.

Does anyone have a suggestion to add the QR codes, the text codes and identifiable information like a location into 1password? 

The only option I see is to create a(or multiple) secure note and add a photo of the QR code and type in other relavent information.

Once I start to get dozens or even hundreds of individual devices, this could get unweildy to manage or use effectively.

Would like to see 1password add a new catagory for adding Smart Home codes and device information.
I think there is an IOS app called Homebase for Homekit that does this, but don't want yet another subscription or tool to manage my information.

Brett
