Fellow homebox user here. As an aside: I've got a storage room with a bunch of shelves and bins. For each bin, I've suck labels on them (using a label maker or sharpie + painters tape), and an NFC tag. Each box in Homebox has its own location, and each NFC tag is a direct link to its instance in Homebox.

It's much easier to categorize larger quantities of things that aren't as valuable as vintage media. Ie. hygiene products, off-season clothing, etc...
