I built the "Harry Potter clock", a screen that shows the location of each family member. It's just and old monitor on the kitchen wall + raspberry pi + zigbee 220V plug to switch it off at night.
I worked beautifully for a few years displaying Apple's "Find My" via a Chromium browser in kiosk mode. However, Apple closed off web access to Find My, so I've now redone it via Google Maps. The Google Maps version doesn't work nearly as well and the maps are cluttered with lot's of stuff you don't want to see, so I'm currently looking at redoing it again by using the Home Assistant app and API.
I suppose the "Find My" app on the Mac could indeed provide the same result more easily, but then I would need to sacrifice a somewhat recent Mac to the project instead of a raspberry pi (... cost times 10)
