Conversely can I use Bluetooth signal strength to find devices within my home ?
- ObsoleteNerd 7y agoFTA: > Using signal strength as a distance meter, I found the phone my fiancée misplaced before she went to work.
- ghaff 7y agoI played around with Bluetooth Low Energy beacons a couple years ago and it seemed really tricky to locate things. Reflections, walls, etc. just introduced too many random variables. I'd love it to be better. (And maybe newer versions of at least full Bluetooth are.) Something I imagine to be useful if it were sufficiently reliable is some sort of "digital tether" between an Apple Watch and iPhone that buzzes you if you get too far separated. (Obviously not something to use all the time but could be useful in some circumstances.)
- vorpalhex 7y agoThis is the idea of tile trackers, except they also emit noise so you can use that once you get pretty close. I'd imagine intentionally directional antennas would be helpful here, much like is used for ham radio foxhunts.
- ghaff 7y agoI keep thinking of trying a tile tracker except that seriously misplacing my keys or wallet is such an unusual event that it seems like sort of an expensive insurance policy given that (I think?) they all have a finite life with embedded battery.
- svachalek 7y agoThere are some with replaceable batteries now. In practice the batteries only last about 6 months though, in my experience.
- vorpalhex 7y agoThey do have a finite life, but it's about a year. There are tiles with replaceable batteries (finally) but they're a bit thicker. I usually buy packs when they go on sale.
