As probably you all know, the geofencing mode in the arlo pro system does not work well. So I was trying to set up ST to arm and disarm my arlo system using my mobile phone as presence sensor, but I have not been able to figure it out.
If you download life 36app and open an account you can link it with smartthings app in and use it as a presence
Once you have got life 360 go into ST app automations , click on smartapps on top right
Scroll down to the + add smart app , scrool down to more and then scroll to bottom and there is life 360 click add
