Want to share my Geolocation and Presence Detector scene i use in my Fibaro setup  In wife's and my own smartphone i use both geofency app and wifi presence to check if we are home. A VD runs scheduled and will update a global variable with value "0" or "1" depends if smartphone is active or not. Geofency app is the most reliable and correct app i use myself because the smartphones wifi turns into "sleep" mode often to save battery.. You could of course only run Geofency if you want.
