We’ve discussed Xandem in the community previously, including some input from their staff. It’s definitely cool Tech, but it remains to be seen how well it will work in a home environment rather than warehouses. For one thing, I’m pretty sure a dog is going to trigger it. And there are other issues about whether it will interfere with zigbee home automation devices. See the discussion thread:
It’s easy to have lights come on when you walk into a room with an ordinary motion sensor. The issue there is it doesn’t know the difference between you walking into a room and your wife walking into a room. The ability to do that is usually called “microlocation.”
(Xandem doesn’t do that, by the way – – it picks up any motion, not a particular person.)
Eventually most engineers think we will probably get this with a device that tracks heartbeats. But for now if you want to uniquely track two different people in one house, each has to carry a device with them. My personal hope is that eventually this will be able to be a smartwatch in th future, but for now it has to either be an iBeacon or a phone.
Estimote has location beacons which can map a room, but it requires 4 beacons per zone, and that gets pretty expensive.
You can find more discussion of micro location in the project reports on the quick browse lists in the community – created wiki. Just look for the “presence” list.
