You can’t do anything there. **Developer response:** The system is based on geofencing so it knows you're not at home so there's no need for face detection. Not sure what seems to be the issue here, but support at alarmhandler dot com can help you get going :) ## Frequently asked questions about Alarmhandler Sensor ### How do I set up Alarmhandler Sensor with an old phone?
