It might just be me, but I don't actually understand what the project is. The readme says since things about storage but I didn't get anything more.
The Project therefore is a simple tool to scan your products and keep a list of the things you have (with the amount). If you're on your way to the grocery store and you realise, that you don't really know if you need this or that product, you can simply VPN into your home network and check the stuff you have at home.
Did this make it any clearer ?

I like the project, don't get me wrong, but for me personally it would just add a layer of complexity.
