I searched "presence" on HPM and a ton of results came up. There seems to be ways to determine presence with "presence sensors" which I cannot find online for Z-Wave, only motion/light sensors. Theres ways to use your phone with a bluetooth gateway of some kind, GPS, apps.
I saw the Hubitat app on the Android Playstore has 2.5 stars and most complaints are about location/GPS not working correctly.
For a noob, what is the best way to determine presence right now? I would prefer to base it off my phone. What Hub app and Android app is everyone using for that?
