If the installer fits a limit switch or reed switch and connects to the input on the intercom, you can use the check gate status button. This also sends a special command by sms and the intercom will reply to notify if the gate is open or closed.
The trigger gate button speed dials the gate intercom sim phone number for you. It is an easier way to open your gates than finding the number in your phone directory. If the installer had stored your phone number in the intercom memory for caller id access, then this will work.
All of these features need the default commands entered in the settings menu along with the intercom sim number before the app will work.
Note- If you are using your gates on step by step mode, and not using automatic closing mode, then the hold open and unhold buttons should not be used.
