Google is reportedly launching an airtag competitor tomorrow. I'm interested to see the details. I have a pair of their headphones, and they don't broadcast when the case is close, which makes them easy to loose.
Wait, I can purchase $2-$4 "find hub" compatible beacons all day and have been for months. I have even made my own using a CR2032 + ESP32-C3 and they work fantastic with "find hub" - is this just an official version of that or something else entirely?
When I lost my phone I put in one earbud and walked around the area listening for the connection sound.
Turns out it wasn't useful because someone else had taken it to lost and found within a few minutes of me losing it, before I knew I'd lost it. But it was a good idea.
A few years back I was shoveling knee deep snow when I completely lost a white earbud. The app had a 'find my bud' feature, but when I activated it I couldn't hear anything. I pulled out the 2nd bud as a test, and it started chirping like a bird. Ironically, it was a beautiful day out so the sound just blended in with the other chirping birds all around. I ended up slapping my snow shovel on the ice a few times until one chirp remained!
If you have multiple fixed BLE receivers, you can do full trilateration. This project integrates into Home Assistant using HA proxy BLE receivers to track phones moving around in your house: https://github.com/agittins/bermuda
Weirdly Apple seems to have something like this built-in for finding an apple TV remote - but the same flow doesn't appear to be launchable for any other device
What an awful website for such a wonderful feature. I don’t expect to see this in the original Find My (Apple’s) as their implementation is fully custom and works altogether differently (and already had a protocol-level rewrite not too long ago), but this is still really cool. Of course needing to be in range of the device is always a problem; some ear buds will drop out altogether if you walk to the next room.
Maybe I'm misremembering, but for example my esphome proxies in HA will show nothing for ages at night while my phone isn't being interacted with.
If the phone is lost, it's probably not super awake lol

That's an entirely different technology, and if you look at it from an RF lens, a highly impressive one.
Make your phone alert when one walks into a room within several meters
