3D location?

[JDRoberts]

I would agree that Ibeacons are likely the most practical way to implement this at the present time. It’s still a 360° signal, but with the more expensive beacons you can vary the transmission strength to reduce the range significantly. I have mine set up so that I’m not detected as “home” until I reach the wheelchair ramp at my front door. The whole detection area is only about 3 m.

A dual device approach to geopresence for smaller areas (sequential detection)

Continuing the discussion from Smart Presence Sensor randomly "leaving" and "returning": Battery life is fine on my presence fob, but I still get random drop-offs with both the fob and the phone presence. Using an idea from @DigitalM0nkey , I am changing over the way I use presence sensing for all activities. I’m now using dual devices at the geo-fence barrier, as well as a virtual presence sensor for better continuous occupancy indication. Basically I’m trying both reduce the range and improve reliability by using two devices that will be recognized in sequence rather than both at the same time. So this is how it will work at my house now: Smartthings recognizes that my phone or the fob, mainly the fob , has entered the Geo fenced area. but nothing else happens yet. I do not tri…
