The answer is yes. I have my mobile phone as a presence detector and my tablets are not.
You have to add the mobile phone as a presence sensor under “Connect New Device”
If both are there you need to delete one. One for most mobile devices presence is weird. I would never have it trigger my garage door. The delay can be pretty bad, my range is about 1 mile and sometimes it happens at the mile marker, and others closer to 2 minutes after I am in the house. A few times in the middle of the night it recognized that I came back home, but never left.
For garage doors I would recommend getting a zwave presence detector, it should trigger 20-50 feet from the house.
