For Auto Open setup, first check your phone settings:
Android location setting:
Privacy and safety -> Location -> Location method -> GPS, Wi-Fi, and Mobile networks. If it's GPS only then it will not work.
Enable Motion and Fitness in your phone settings.
Setup Auto Open in Nexx Garage App:
1. Menu (3 little bars at top left)>Settings>Auto Open [Enable Auto Open Door], [Enable Active Period and set enabled time].
2. When you are at home, from the App, go to menu>configure device, tap "Update Device Location".
3. Log out and then log back in.
4. Drive test: drive 1 mile away from home and then come back. Have your phone in the open (not in your pocket/purse/enclosed compartment) when you are going towards your garage.
5. Garage door should automatically open.
