I lost a bunch of keys today. It sucks and it’s gonna cost me a lot of money to replace the locks. I want to to add an airtag-like device to my key ring in the future. However I don’t know of any device that works in a similar fashion, either through bluetooth or GPS, that works with Graphene and doesn’t require some kind of privacy invading online subscription.
Do you have any advice on privacy respecting alternatives to airtags?


Seeed meshtastic tracker card. The general purpose version uses more battery than I’d like but you can get one that only does tracking or turn off most of features to get more than a few days of life.
It only works if you have some other meshtastic nodes around, but it doesn’t need to be a lot and it’s getting to be more popular.
