Your fridge must be a complex place to navigate. We have 70cm wide tall Siemens one and what we have vs what is missing is a question of maybe 10-15s check. This covers 4 people.

Chest freezers would be more tricky if full and could take maybe up to a minute but we don't have those. If you are bad at tracking, make a list.

No, we really don't need 'smart' fridges and people should vote with their wallets.
