I would love to be able to create a wireless presence sensor that works over a few miles but unsure if this is even possible. as using geofence is useless in the scenario i am after, I’ve tried but it never triggers.
What I want to do is have an announcement for the wife and kids if I am flying over our house. But with a cruise speed of 85 knots, as I said mobile presence doesn’t trigger in time and I am in and out of the geofence area before the mobile phone realises its there…unless I load up the ST app or life360 app manually when I am above the house…but TBH It’s not something I should be doing as my house in the region of some big hills…i don’t want to hit some cumulus granitus due to lack of care and attention 
My zigbee presence sensor unsurprisingly doesn’t work either. Any ideas of what wireless technology (if any) could achieve this? Unless of course I could get some kit to pick up my planes transponder… .but I imagine that would be far too expensive
