Freezer contents 🥶🗓️👨🏼‍🍳🍽️

Objective

Food gets put in the freezer and often forgotten about. Now I have a solid meal planner solution running over at https://github.com/jcallaghan/The-Cookbook/projects/10 with lots of automation like calendar integration etc. I'd like to incorporate a way to capture and display what's in the freezer. What I'm looking for is an easy way to add/remove items from some kind of list, with a way to have visibility of this over in cookbook repo and to be able to show it

Consideration	Notes
Paper	This worked when I tried before but it's not very 21st century.
To Do	When I tried this it fell out-of-date very quickly so I sacked it off.
OneNote	Similarly to To Do this very quickly became out-of-date.
Grocy	I always feel I would massively benefit from running Grocy, particularly with my love of food, tracking my pantry ingredients, managing chores and maintaining a family and household wiki. It might be time to give it a go.
Home Assistant Shopping List integration	This feels like it is the closet to what I am looking for to maintain this list locally, the problem with the Shopping List is it is just that, a shopping list. I'd love to see a spin off where it can support multiple lists and the Lovelace card could then show all items or items just from one or many lists. I may even have a go at making this myself. The benefit with the Shopping List is that it writes the list to a json file I believe which could then be accessed and potentially I could automating syncing this with my cookbook repo. It also means that I could show it on the Home Assistant tablet we have in our kitchen.
eInk display	Placing an eInk close to the freezer would help with visibility and to promote updating the list as things are added or removed.

eInk display

I have just brought a ‎4.2inch NFC-Powered e-Paper Display to test. The reason for going for this model is that is comes with a case where as most others don't. Seeing as I don't have time or a working 3D printer this will help me maintain my rule about not have exposed solutions or projects on display.

I'm hoping I can use the SPI interface on an ESP32 running ESPHome to and connect to the display and remove the need to use NFC to update the displays contents.

The kind of remind me of the eInk displays use to show the price in European supermarkets. I always admired them when travelling and questioned why they never caught on in UK supermarkets.

These are pictures after using the app to write text, which is then saved as an image and then sent to the screen via NFC.
