Some flows are only activated if all members of the family are out.
For that, I use the geofencing functionality of the IFTTT app (it updates a variable)
To be honest, it is not always reliable.
With Homey, would it be possible to do geofencing with Bluetooth ?
Other potential solution : Do you know if a z-wave badge could be detected when it is at home?
I don’t want a badge that requires an action from the user.
