Tbh I am a messy person, I trained myself to be organized but I still struggle to not lose my keys and I want something like the apple tag but FOSS, I’ve thought of an ESP32 or ATTINY with a bluetooth module but I don’t think apple uses that? It has to be durable and friendly with LineageOS, samsung stock and my dad lol.
Strictly speaking, there isn’t one.
The tag tracking options on ios and android work because they rely on mesh networking with those devices.
Without a huge mesh network of billions of phones, computers and tablets, this technology doesn’t work.
Even if you only wanted it to work in your house, there isn’t something like that in the floss world.
A better option if you would prefer not to switch to ios or stock (?) android is the tile tags. They don’t have a huge network but if you need to figure out where your keys are in the house they work pretty good.
You gotta keep the batteries rotated though, but that’s part of the dad compatibility…
