How tablet can find out that one or more phones aren't home
Posted: 28 Apr 2017 12:07
My tablet (sm-t111, Android 4.4, Automagic) is a smart remote. I use it to remote my lighting system (Philips Hue). Everything is ok.
But I want to use my smartphone (S5, Android 7.1.2, Automagic)) as "a key" and S3 (Android 5, Automagic)
When I come home I want my tablet to "catch" my smartphone to turn lights. And when I left my home I want my tablet to "catch" this state and turn off the lights.
Problems:
There are two people with smartphones.
When we left home we don't internet accsses so I need in order to my tablet find out that nobody is home and turn off the lights.
Bluetooth?
Wifi?
