You must first connect your phone to your Wi-Fi home network or gain internet access on the 3g/4g network. Once you are connected, you should have complete control over your garage doors or gates. Now, open the app, and on the main screen, you will be able to control each door that is connected to the iSmartgate device. If you have more than one door, scroll down to the specific door that you would like to open, and slide the padlock up or right to open your garage door.
If you want to close the door, simply follow the same method. However, this time you should slide the padlock icon down or left.
