Hi! I figure there are a lot of smart folks here so thought I'd ask.. What I am looking for is something I can buy where there are two devices (No smartphones).. Basically you put this one tracker little device attached to your keys (device A) and the other to a bracelet that you always wear (device B) So you're travelling and you leave your keys at a restaurant and when you walk out, the device B on your bracelet beeps. I am even ok with if the devices "ping" each other every day 5 min and get a beep after 5 min.. The point is, especially when you are travelling and moving from places to places a lot, you just want to be warned if you left things behind in a short time/distance from when you left it.. I am not looking to "Find" things.. So all these Tiles and TrackR and PebbleBees and Proximo Trackers seem to be tag to phone (and phone to tag).. Am I explaining it right? I will make sure I wear the bracelet.. I just want the device on bracelet to beep if the device on the keychain or wallet gets too far (or can't ping ) from the device on the bracelet.. Help Pwlease!
