Z Wave or Zigbee Presence Bracelet?

So I’ve been looking for a few days, but can’t find anything. Does anybody know of a presence sensor in a bracelet form factor?

I don’t know of any using Z wave or zigbee, you have to use The key fob, although it can be worn as a pendant if that’s of any help.

There are I beacons which can be worn as bracelets. But they don’t talk to smartthings directly, so setting them up gets a little complicated. See the presence FAQ for more discussion:
