There is a unofficial API for “ICA” ( Grocery store ) that would allow you to add to s a shopping list.
This is shopping list is then synced with the hand scanners in the stores so you can see what you added to your list.
I know this is just like the shopping list in Home-Assistant today but with out the sync fetcher to the hand scanners, it would just be so simple and awesome to be able to add it in Home-Assistant and get it right there in the scanner in the store.
I am however not a good coder so if anyone has a appetite for this it would be awesome!

I am more than willing to help QA this as well if wanted or needed.
