I was looking for a way to connect the Home Assistant Shopping list to the Albert Heijn-app and yesterday I found a working repo written in GO. Together with Claude I converted the GO application to a custom Home Assistant-component.
With this component you can add a shopping list to Home Assistant and that list will automatically sync to the Appie-app. When you stripe an item trough in the Appie-app, this will sync back to the HA shopping list.
I also created two automations to automatically add dishwasher pods to the shopping list when they run on empty and add to the stock when you have bought them
By default the items are added just as text, but with automations you can also add productIds.
