I have since a half a year (due to the discontinuation of the Tado presence service) the following Android Geofencing apps running in my family: Macrodroid, Olisto and EgiGeozone.
They all do the trick, if you put some effort to remove the apps from battery optimisation grant the rights to access google location services). They all use the Get request command to send a message to Homey which you have to include in a webhook flow.
See Tado Thuis/Afwezig na update and the locative manual how to set this up.
