Absolutely! CP:R ihas always been a huge interest of mine, I also have 2020 and many supplements but never had a chance to dive in.

I have a very similar situation: a cat with a severe kidney disability, meds 5 times a day with at least 2h between each. We’ve been using a whiteboard but I am currently setting a smarter solution. My WIP setup is a raspberry pi with a static IP on my local network and a FastAPI app. This way I can also do a household to-do lists (did anybody watered plants recently?) and add connection to local smart lights (effects if meds could not be given with 2h interval before our usual go-to-bed time), etc.

It would only work for us since it is a household only solution. Our cats do not travel anywhere and I do not currently need to check for these todos when not at home. It may be different for you. Good luck OP, hope you will find something that suits you.
