Presence detection (Mobile) and timing of actual mode change

[JDRoberts]

This is how I’m using two devices together to verify occupancy:

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…

BTW, as it happens, a friend of mine is helping me this coming week with an experiment where we are going to use an Ibeacon as a second device for the occupancy scenario. He’s got several that he’s bringing over and we’re using ifttt as a “man in the middle” to flip a SmartThings virtual switch. Although we’re also going to experiment with the app from Beacon sandwich.

Anyway, if this works, it won’t need a contact or motion sensor.
